Description

[0001] The present invention relates to an operating device with a touch-sensitive screen for a floor cleaning machine and a system comprising a floor cleaning machine and an operating device.

[0002] Such control devices are used to operate floor cleaning machines. This allows large floor areas, for example, in public buildings or supermarkets, to be cleaned, with the control device allowing the machine's settings to be adjusted.

[0003] Control devices known from the prior art are designed to display specific information to an operator of the floor cleaning machine. Furthermore, such control devices allow the operator to enter inputs for operating the floor cleaning machine on a control device.

[0004] US 2017 / 0 201 617 A1 and EP 2 980 670 A2 each disclose a mobile terminal with which a corresponding cleaning robot can be operated.

[0005] When operating floor cleaning machines, it is desirable for the operator to be able to enter certain commands, such as specifications regarding the speed and steering angle of the floor cleaning machine, into the floor cleaning machine as simply and user-friendly as possible. Furthermore, with autonomous floor cleaning machines, it may be necessary to enter additional parameters in addition to speed and steering angle, or to move the machine back to a preset working path.

[0006] It is therefore an object of the present invention to provide an operating device as described above in such a way that operator commands can be entered in a simple and user-friendly manner.

[0007] The object is achieved by an operating device with a touch-sensitive screen for a floor cleaning machine, wherein the touch-sensitive screen is designed to display a zero point, wherein the operating device is designed such that by touching the touch-sensitive screen a touch point that can be moved along the touch-sensitive screen is defined, wherein the touch-sensitive screen is designed to display the touch point, wherein the operating device is designed to determine a vector between the zero point and the touch point by an operator operating the touch-sensitive screen,wherein a projection of the vector onto a straight line running along the touch-sensitive screen defines a steering angle of the floor cleaning machine and / or a further projection of the vector onto a further straight line running along the touch-sensitive screen defines a speed of the floor cleaning machine, and wherein the operating device is configured to output control signals to the floor cleaning machine corresponding to the defined steering angle and / or the defined speed.

[0008] This provides an operating device that enables simple and user-friendly operation of a floor cleaning machine.

[0009] By using a touch-sensitive screen, in particular a touchscreen, one and the same device can be used to provide information and enter instructions. The display of the zero point allows the operator to identify the starting point of the vector at any time on the touch-sensitive screen. Using the movable touch point, the operator can determine the length of the vector, i.e., the magnitude of the vector, as well as the orientation of the vector. By projecting the vector onto the straight line or onto the further straight line, the vector is broken down into its components. This allows the steering angle of the floor cleaning machine or the speed of the floor cleaning machine to be defined in a way that is intuitive for the operator.

[0010] In one embodiment, the zero point, in particular the position of the zero point on the touch-sensitive screen, can be determined by the operator operating the touch-sensitive screen, in particular by a finger of the operator, for example by the operator's thumb. This allows the operator to determine different starting points of the vector. This allows the operator to operate the machine according to their preferences, for example with their thumb or another finger. The flexible positioning of the zero point allows adaptation to the hand or hand size of the operator. This further increases user-friendliness and flexibility during operation.

[0011] In a further embodiment, the vector can be determined by moving the touch point along the touch-sensitive screen. This allows the operator to determine the vector, and in particular the direction and magnitude of the vector, using a familiar sliding or swiping motion. This further increases user-friendliness.

[0012] In one embodiment, the touch-sensitive screen is designed to display a further zero point, wherein the operating device is designed such that by touching the touch-sensitive screen, a further touch point that can be moved along the touch-sensitive screen is defined, wherein the touch-sensitive screen is designed to display the further touch point, wherein the operating device is designed to determine a further vector between the further zero point and the further touch point by the operator operating the touch-sensitive screen, wherein a third projection of the further vector onto a third straight line running along the touch-sensitive screen defines the steering angle of the floor cleaning machine or the speed of the floor cleaning machine, and wherein the operating device is designedTo output control signals to the floor cleaning machine according to the defined steering angle or the defined speed.

[0013] By providing an additional zero point, a contact point, and a vector, the operator can determine the steering angle and speed of the floor cleaning machine with two independent movements. This further increases the flexibility of the floor cleaning machine's operation and user-friendliness.

[0014] In a further embodiment, the further zero point, in particular the position of the further zero point on the touch-sensitive screen, can be determined by the operator operating the touch-sensitive screen, in particular by a finger of the operator, for example by the operator's thumb. This enables the operator to determine different starting points of the further vector. The operator can therefore operate the machine according to their preferences, for example with their thumb or another finger. The flexible positioning of the further zero point allows adaptation to the hand or hand size of the operator. This further increases user-friendliness. Alternatively, it is provided that the further zero point, in particular the position of the further zero point on the touch-sensitive screen, is fixedly defined or predetermined.Preferably, the further contact point can be moved on a fixed axis and thus determine the magnitude of the further vector for the steering angle or the rotation of the floor cleaning machine or the speed of the floor cleaning machine.

[0015] In a preferred embodiment, the further vector can be determined by moving the further touch point along the touch-sensitive screen.

[0016] This allows the operator to determine the vector, and in particular the direction and magnitude of the vector, using a familiar sliding or swiping motion. This further increases user-friendliness.

[0017] In a further embodiment, either the straight line and the further straight line or the straight line and the third straight line extend perpendicular to one another. As a result, the vector is split into two components that run orthogonally to one another, or the straight line and the further straight line or the straight line and the third straight line are arranged orthogonally to one another, so that operation of the floor cleaning machine is particularly intuitive for the operator, since the steering angle can be determined via one component and the speed via a further component that runs perpendicular to this. Preferably, the vector is broken down into two straight lines, wherein the forward speed and the rotational speed or the steering angle can be determined via the two straight lines.

[0018] In a further embodiment or a further independently inventive aspect of the present invention, the touch-sensitive screen is configured to display a predetermined route for the floor cleaning machine within an overall area and a current position of the floor cleaning machine within the overall area. This allows the operator to use the touch-sensitive screen to determine the progress of a journey, in particular a cleaning journey, of the floor cleaning machine along the predetermined route.In addition, the operator can easily determine whether the floor cleaning machine is on the predetermined route while the floor cleaning machine is traveling along the predetermined route and, if the floor cleaning machine is not on the predetermined route, can intervene in the further movement of the floor cleaning machine, for example by stopping the floor cleaning machine or moving it back to the route.

[0019] Here, the overall area is an area in which one or more floor surfaces to be cleaned are located. Within this overall area, the floor cleaning machine can move along a transport path to a floor surface that is dirty and therefore needs to be cleaned, or move between several such floor surfaces to be cleaned. The floor cleaning machine often includes a cleaning element that can be activated to intervene in a floor surface. While the floor cleaning machine is moving along a transport path, the cleaning element is deactivated so that the floor cleaning machine can quickly approach different floor surfaces to be cleaned. The floor surface or surfaces to be cleaned, also called work areas, can be cleaned by the floor cleaning machine along predetermined routes or freely definable work paths.During movement of the floor cleaning machine along the predetermined route or a working path, the cleaning element is activated at least along sections of the predetermined route or the working path so that the floor area to be cleaned can be cleaned.

[0020] In one embodiment, the touch-sensitive screen is configured to display a starting area within the overall area. This allows the operator to use the touch-sensitive screen to determine an area within the overall area in or near which route guidance can begin.

[0021] In a further embodiment, the touch-sensitive screen is configured to display the starting area when an autonomous process of the floor cleaning machine is interrupted. This allows the operator to determine an area within the overall area to which the floor cleaning machine must be moved, for example, to restart or continue the autonomous process.

[0022] In one embodiment, the touch-sensitive screen is configured to display the starting area as long as the floor cleaning machine has not reached the starting area. This allows the operator to have the starting area displayed in a first form as long as the floor cleaning machine is moved toward the starting area. Preferably, the touch-sensitive screen is configured to display the starting area in a second form that differs from the first, or to no longer display it once the floor cleaning machine has reached the starting area. This provides a simple signal to the operator that the floor cleaning machine has reached the starting area.

[0023] In one embodiment, the touch-sensitive screen is designed such that the starting area is displayed in a first form as long as the floor cleaning machine has not reached a predetermined orientation in the overall area. This makes it easy for the operator to recognize when an optimal orientation of the floor cleaning machine for starting or continuing a cleaning process has been reached. Preferably, the touch-sensitive screen is designed such that the starting area is displayed in a second form that differs from the first, or is no longer displayed when the floor cleaning machine has reached the predetermined orientation in the overall area. This easily signals to the operator that the floor cleaning machine has reached the predetermined orientation.

[0024] In a further embodiment, the operating device is designed such that, if an autonomous process of the floor cleaning machine is interrupted at an interruption point, a transport path is determined, wherein the transport path extends between the interruption point and another current position of the floor cleaning machine. This makes it easy for the operator of the floor cleaning machine to move the floor cleaning machine back to the interruption point using the transport path. Furthermore, it is possible to start another autonomous process of the floor cleaning machine, with the aid of which the floor cleaning machine travels along the transport path and thus returns to the interruption point. While the floor cleaning machine is moving along the transport path, the cleaning element of the floor cleaning machine is deactivated so that the floor cleaning machine can quickly return to the predetermined route.Preferably, the transport path is temporarily recorded, for example in the operating device, and is, if necessary, automatically followed by the floor cleaning machine “backwards”, ie in the direction of the specified route, preferably from the end of the interruption (of the autonomous process).

[0025] In one embodiment, the touch-sensitive screen is designed to display a control element. The control element is preferably a brush ejection button, an on / off switch for a work light, a horn button, a chemical dosing switch, a button for activating a suction foot / handheld vacuum tool, a brush drive button, a speed reduction button, a travel direction selector switch, a button for autonomous functions of the floor cleaning machine, such as a start / stop button, a button for loading routes, or a record button for recording routes. In one embodiment, the touch-sensitive screen is designed to display an information element. The information element is preferably an illuminated display, for example for showing operating hours, odometer, current speed, battery capacity, etc.Battery status and / or current water capacity, or a warning device for forward travel of the floor cleaning machine, which signals to the operator that the floor cleaning machine is in forward travel mode. In one embodiment, the touch-sensitive screen is designed to display an error element. The error element is preferably an illuminated display or an indicator, for example, that a spare part needs to be replaced or cleaning fluid needs to be refilled, or that there is an error in the floor cleaning machine or robot, such as a sensor defect, in particular a camera defect, incorrect localization of the floor cleaning machine, and / or an error in the drive system.

[0026] A further subject of the present invention is a system comprising a floor cleaning machine and an operating device according to the invention. The advantages of the operating device according to the invention also apply to the system.

[0027] In one embodiment, the floor cleaning machine and the operating device are detachably connected to one another. Preferably, the floor cleaning machine and the operating device are connected to one another in a form-fitting and / or force-fitting manner. The detachable connection enables the operator, on the one hand, to operate the floor cleaning machine with the operating device attached to the floor cleaning machine, and, on the other hand, to operate the floor cleaning machine with an operating device not attached to the floor cleaning machine, so to speak, remotely. For example, when the floor cleaning machine is not in operation, it is advantageous if the operating device is attached to the floor cleaning machine in order to enable, for example, the assignment of the operating device and the floor cleaning machine in a storage area in which several floor cleaning machines are parked.When the floor cleaning machine is in operation, it is advantageous if the control device is not attached to the floor cleaning machine and the control device and the floor cleaning machine can be operated in a remote mode.

[0028] In one embodiment, the system comprises data transmission means for wireless data transmission between the floor cleaning machine and the operating device. This allows data to be transmitted from the floor cleaning machine to the operating device and from the operating device to the floor cleaning machine without complex wiring. This is advantageous, for example, in remote mode. Preferably, the floor cleaning machine and the operating device each comprise a transmitter and a receiver.

[0029] In one embodiment, the system comprises a holder or a mounting, wherein both the floor cleaning machine and the holder or mounting, as well as the operating device and the holder or mounting, are each detachably connected to one another, in particular by form-fitting and / or force-fitting. This makes it easy for the operator to attach the operating device to the floor cleaning machine. The holder is preferably a tablet holder. This makes it possible for the operator to use a tablet as the operating device. The operating device is preferably a tablet or a smartphone. The operating device is preferably designed for operation via an app.

[0030] In one embodiment, the system comprises a supply device. In one embodiment, the supply device comprises a charging station.

Preferably, the supply device comprises a device for cleaning a tank of the floor cleaning machine. Preferably, the supply device comprises a waste container for the floor cleaning machine, in particular for a sweeper.Preferably, sweepings from the sweeper can be automatically unloaded into the waste container. This allows the floor cleaning machine to be provided with various supply devices throughout the area. The floor cleaning machine and / or the operating device can be supplied or charged using the supply device or the charging station. The supply device preferably comprises a battery charging station for charging a battery of the floor cleaning machine and / or for charging a battery of the operating device. The system is preferably designed such that the operating device can be supplied, in particular charged, wirelessly by the supply device. For example, the system is designed such that any tablet and smartphone can be charged wirelessly by the supply device. The floor cleaning machine and the supply device are preferably detachably connected to one another.The floor cleaning machine and the supply device are preferably connected to one another in a form-fitting and / or force-fitting manner. With the aid of the supply device or charging station which is detachably connected to the floor cleaning machine, the operating device can be supplied with power or charged, for example, when the operating device is arranged in the immediate vicinity of the floor cleaning machine, for example when the operating device is placed on the floor cleaning machine. The floor cleaning machine and the supply device are preferably arranged at a distance from one another. The supply device is preferably arranged in a stationary manner within the overall area. With the aid of the supply device or charging station which is arranged at a distance from the floor cleaning machine, preferably in a stationary manner within the overall area, the floor cleaning machine or the operating device can be supplied with power or charged, for example.be charged when the floor cleaning machine or the operating device is moved to the supply device or charging station. The supply or charging functionality can thus preferably be available both directly on the floor cleaning machine and at the separate charging station. The floor cleaning machine preferably comprises a shelf for depositing the operating device. The system is preferably designed such that by placing the operating device or the tablet or the smartphone on the shelf, the operating device or the tablet or the smartphone is wirelessly charged via the supply device. In this way, commercially available devices can be used as the operating device and the operator can use his own device as the operating device.

[0031] In one embodiment, the system is configured to reduce the speed of the floor cleaning machine in curved areas of the predetermined route and / or transport path. In another embodiment, the system is configured to reduce the speed of the floor cleaning machine when the distance between the floor cleaning machine and an obstacle in the overall area falls below a threshold value.

[0032] In the following, exemplary embodiments of the operating device according to the invention are described with reference to merely exemplary schematic drawings, in which Fig. 1 shows a schematic drawing of a display on the screen of a first embodiment of an operating device according to the invention, Fig. 2 shows a schematic drawing of a display on the screen of a second embodiment of an operating device according to the invention, Fig. 3 shows a schematic drawing of a display on the screen of a third embodiment of an operating device according to the invention, Fig. 4 shows a schematic drawing of a first representation on the screen of a fourth embodiment of an operating device according to the invention, Fig. 5 shows a schematic drawing of a second representation on the screen of a fourth embodiment of an operating device according to the invention and Fig. 6 shows a schematic drawing of a third representation on the screen of a fourth embodiment of an operating device according to the invention.

[0033] Fig. 1 shows a schematic drawing of a display on the screen of a first embodiment of the operating device 1 according to the invention. The operating device 1 is provided for a floor cleaning machine. The operating device 1 comprises a touch-sensitive screen 2. As shown in Fig. 1, the touch-sensitive screen 2 displays a zero point 3 and a touch point 5. Alternatively, it is provided that the touch-sensitive screen 2 only displays the touch point 5 and does not display the zero point 3. By touching the touch-sensitive screen 2, the zero point 3 and the movable touch point 5 are defined. The movable touch point 5 can be moved along the touch-sensitive screen 2 by an operator of the operating device 1. Fig. The contact point 5 shown in Figure 1 can also be referred to as a freely positionable or active joystick.

[0034] The zero point 3 is in Fig. 1 is shown as a circle. However, any other representation of the zero point 3 is also possible. The contact point 5 is in Fig. 1 is shown as a filled circle. However, any other representation of the contact point 5 is also possible.

[0035] Furthermore, Fig. 1 a vector 7 represented as an arrow, which is preferably not displayed by the operating device 1. The vector 7 extends between the center of the zero point 3 and the center of the contact point 5. The arrow representation of the vector 7 symbolizes a possible wiping direction of a wiping movement of the operator, with which the operator has determined the current contact point 5 starting from the zero point 3.

[0036] Furthermore, Fig. 1 a projection 8 of the vector 7. The projection 8 is a projection onto a straight line 9 running along the touch-sensitive screen 2, which is also in Fig. 1, but preferably, just like projection 8, is not displayed by operating device 1. Projection 8, in particular the magnitude of projection 8, defines a steering angle of the floor cleaning machine. Preferably, the steering angle of the floor cleaning machine is an angle between a current orientation of the floor cleaning machine in an overall area and a position of the front or rear tires of the floor cleaning machine.

[0037] Fig. 1 further shows a further projection 10 of the vector 7 onto a further straight line 11 running along the touch-sensitive screen 2. Preferably, neither the further projection 10 nor the further straight line 11 is displayed by the operating device 1. In the Fig. In the embodiment shown in Figure 2, the straight line 9 and the further straight line 11 extend perpendicular to each other. The further projection 10 defines, particularly through its magnitude, the speed of the floor cleaning machine.

[0038] The Fig. The zero point 3 shown in Figure 1 can be determined by the operator of the touch-sensitive screen 2. This is possible, for example, by the operator touching the touch-sensitive screen, for example with the operator's finger. Touching the touch-sensitive screen also defines the movable touch point 5, which can be moved along the touch-sensitive screen 2. Thus, by moving the touch point 5 along the touch-sensitive screen, the operator can determine the vector 7 and thus the steering angle and speed of the floor cleaning machine. The operating device 1 determines the lengths of the projections 8, 10 and generates a control signal for the floor cleaning machine from this.

[0039] Fig. 1 also shows three control elements 29, 29', 29", which are displayed by the touch-sensitive screen 2. The control elements 29, 29', 29" are, for example, control buttons. Preferably, one of the control elements 29, 29', 29" is a brush release button, an on / off switch for a work light, a horn button, a chemical dosing switch, a button for activating a suction foot / handheld vacuum tool, a brush drive button, a speed reduction button, a travel direction selector switch, a button for autonomous functions of the floor cleaning machine, such as a start / stop button, a button for loading routes, or a record button for recording routes. Furthermore, Fig. 1 two information elements 31, 31', which are, for example, two information displays. Preferably, one of the information elements 31, 31' is an illuminated display, for example, for displaying operating hours, odometer, current speed, battery capacity or battery status and / or current water capacity, or a forward travel warning device, which signals to the operator that the floor cleaning machine is in forward travel mode. In addition, Fig. 1 two error elements 33, 33', which are designed, for example, as error indicators. Preferably, one of the error elements 33, 33' is an illuminated display or an indicator, for example, that a spare part needs to be replaced or cleaning fluid needs to be refilled, or that there is an error in the floor cleaning machine or robot, such as a sensor defect, in particular a camera defect, incorrect localization of the floor cleaning machine, and / or an error in the drive system.

[0040] Fig. 2 shows a schematic drawing of a representation on the screen of a second embodiment of the operating device 1. In this embodiment, the projection 8 of the vector 7 onto the straight line 9 running along the touch-sensitive screen 2 defines the steering angle or the rotation angle of the floor cleaning machine, as already described in connection with Fig. 1. Preferably, with the joystick 3, 5, 7, 8 used here, only the direction of rotation or the steering angle or the angle of rotation is evaluated, i.e. the horizontal displacement of the contact point 5 relative to the zero point 3.

[0041] Additionally, Fig. 2, a further zero point 3', a further contact point 5', and a further vector 7' represented as an arrow. Preferably, the further zero point 3' and the further vector 7' are not permanently displayed by the touch-sensitive screen 2, but only when the contact point coincides with the zero point or no contact point has yet been determined. Alternatively, the further zero point 3' and / or the further vector 7' can be displayed by the touch-sensitive screen 2. Preferably, the further vector 7' is not displayed by the touch-sensitive screen 2.

[0042] If the touch-sensitive screen 2 is not touched by the operator, the further touch point 5' is preferably arranged such that the center of the further touch point 5' and the further zero point 3' are arranged congruently, i.e. the magnitude of the further vector 7' extending between the center of the further touch point 5' and the further zero point 3' is zero. It is preferably provided that if the further touch point 5' has been moved out of a starting position congruent with the further zero point 3' and the touch-sensitive screen 2 is subsequently no longer touched by the operator, the further touch point 5' is preferably arranged at the point of the last touch of the touch-sensitive screen 2 by the operator.In other words, the additional contact point 5' is preferably moved into position once and remains in position until it is moved to another position, i.e. the additional contact point 5' can be or is determined by user input. The additional contact point 5' in . Fig. 2 is designed as a slider of a slider controller or as a preselection slider and is displayed by the touch-sensitive screen 2. This slider can be moved by the operator along a third straight line 13, which runs along the touch-sensitive screen 2. As a result, the further vector 7' is determined by the operator. Preferably, the touch-sensitive screen 2 is designed to display a scale, wherein the scale preferably specifies the steps in which the further contact point 5' or the slider can be moved. In the Fig. In the embodiment shown in Figure 2, the straight line 9 and the third straight line 13 extend perpendicular to each other.

[0043] One in Fig. 2, but not displayed by the touch-sensitive screen 2, defines the third projection 12 of the further vector 7' onto the third straight line 13, in particular by its magnitude, the speed of the floor cleaning machine. In Fig. 2, the further vector 7' corresponds to the third projection 12 of the further vector 7', since the further vector 7' and the third straight line 13 have the same orientation. For example, if the further origin 3' and the further tangency point 5' are like the one in Fig. 1 shown zero point 3 and the one in Fig. 1 and the operator does not move the further contact point 5' along the third straight line 13, the projection 12 would not correspond to the vector 7' and the speed of the floor cleaning machine would be determined by the component of the further vector 7' along the third straight line 13, i.e. the projection 12, by generating corresponding signals from the operating device. Preferably, the further touch point 5' is movable along the touch-sensitive screen 2 between a predetermined position 4 and a predetermined further position 6. Alternatively, the further touch point 5' is movable along the touch-sensitive screen 2 beyond position 4 and beyond the further position 6. This allows a higher speed to be determined. The scale preferably extends between the predetermined position 4 and the further predetermined position 6.

[0044] The Fig. The additional zero point 3' shown in Figure 2 cannot be determined by the operator of the touch-sensitive screen 2. In other words, the additional zero point 3' has a predetermined position within the touch-sensitive screen 2. By touching the touch-sensitive screen, for example with the operator's finger, the movable additional touch point 5' is defined, which can be moved along the touch-sensitive screen 2. Thus, by moving the additional touch point 5' along the touch-sensitive screen 2, the operator can determine the additional vector 7' and thus the speed of the floor cleaning machine. Moving the additional touch point 5' is possible starting from the additional zero point 3' or by touching the touch-sensitive screen 2 for the first time above or below the additional zero point 3'.Preferably, the operating device 1 is designed such that touching the contact point 5 releases the floor cleaning machine to move.

[0045] Fig. 2 also shows the already in Fig. 1 and in the description in connection with Fig. 1 described three control elements 29, 29', 29", two information elements 31, 31' and two error elements 33, 33'.

[0046] Fig. 3 shows a schematic drawing of a representation on the screen of a third embodiment of the operating device 1 according to the invention. The further zero point 3', the further contact point 5', the further vector 7', the third projection 12 and the third straight line 13 as well as their functionality in Fig. 3 correspond to the respective components from Fig. 2.

[0047] In the Fig. In the third exemplary embodiment shown in Figure 3, the zero point 3 and the vector 7 are preferably not displayed permanently by the touch-sensitive screen 2, but only when the touch point coincides with the zero point or no touch point has yet been defined. Alternatively, the zero point 3 and / or the vector 7 can be displayed by the touch-sensitive screen 2. When the touch-sensitive screen 2 is not touched by the operator, the touch point 5 is arranged such that the center of the touch point 5 and the zero point 3 are congruent, so that the magnitude of the vector 7 extending between the center of the touch point 5 and the zero point 3 is zero. This corresponds to the Fig. 3 shown arrangement.

[0048] The contact point 5 in Fig. 3 is designed as a slider of a slider controller or as a sideways slider and is displayed by the touch-sensitive screen 2. This slider can be moved along the straight line 9 by the operator along the touch-sensitive screen 2. In the Fig. 3, the straight line 9 and the third straight line 13 extend perpendicular to each other. By shifting the contact point 5 to the left starting from the Fig. The steering angle of the floor cleaning machine to the left is defined in the position shown in Figure 3. By moving the contact point 5 to the right from the position shown in Fig. 3, the steering angle of the floor cleaning machine to the right is defined. This defines vector 7, which is shown in Fig. 3 has the absolute value zero. The projection 8 of the vector 7 is in the Fig. 3 is also zero and therefore not shown. The projection 8 defines, in particular by its magnitude, the steering angle of the floor cleaning machine. In the configuration shown in Fig. In the configuration shown in Figure 3, the steering angle is zero. If the operator moves the contact point 5 from its zero position to the left or right along the straight line 9, this results in a corresponding steering angle of the floor cleaning machine to the left or right, respectively, with the control device generating the corresponding signals to the floor cleaning machine.

[0049] The Fig. The zero point 3 shown in Figure 3 cannot be determined by the operator of the touch-sensitive screen 2. In other words, the Fig. 3, the zero point 3 within the touch-sensitive screen 2 has a predetermined position. By touching the touch-sensitive screen, for example with a finger of the operator, the movable touch point 5, in particular its position along the straight line 9, is defined. Thus, by moving the touch point 5 along the touch-sensitive screen 2, the operator can determine the vector 7 and thus the steering angle of the floor cleaning machine. Preferably, the touch-sensitive screen 2 is configured to display a further scale, wherein the further scale preferably specifies the steps in which the touch point 5 or the slider can be moved. Preferably, the touch point 5 is movable along the touch-sensitive screen 2 between a predetermined third position 4' and a predetermined fourth position 6'.Alternatively, the contact point 5 can be moved along the touch-sensitive screen 2 beyond the third position 4' and beyond the fourth position 6'. This allows a higher steering angle to be determined. Preferably, the further scale extends between the predefined third position 4' and the predefined fourth position 6'. Fig. 3 also shows the already in Fig. 1 and in the description in connection with Fig. 1 described three control elements 29, 29', 29", two information elements 31, 31' and two error elements 33, 33'.

[0050] Fig. 4 shows a schematic drawing of a first representation on the screen of a fourth embodiment of the operating device according to the invention. Fig. 4 shows a predetermined route 15 for the floor cleaning machine in a total area 17 as well as a current position 19 of the floor cleaning machine in the total area 17. In addition, Fig. 4 shows a starting area 21 within the overall area 17. Here, the starting area 21 is depicted as a trapezoid. However, any other shape of the starting area 21 is also possible. The predetermined route 15, the overall area 17, the current position 19, and the starting area 21 are displayed on the touch-sensitive screen 2. Fig. 4 also shows the already in Fig. 1 and in the description in connection with Fig. 1 described three control elements 29, 29', 29", two information elements 31, 31' and two error elements 33, 33'.

[0051] The predetermined route 15 is determined, for example, by teaching, wherein the teaching comprises driving the floor cleaning machine along the predetermined route 15. For example, the operator moves the floor cleaning machine along the route 15, and the corresponding sequence of positions in the overall area 17 is recorded by the floor cleaning machine or the operating device. This makes it possible to determine the predetermined route 15 by driving the floor cleaning machine along the predetermined route 15 without importing an environmental model into the floor cleaning machine. Alternatively, it is also possible to determine the predetermined route 15, for example, by entering spatial coordinates into the operating device, wherein the spatial coordinates again define different points along the predetermined route 15.For example, the spatial coordinates are entered by the operator using a stylus to draw or paint the predetermined route 15 into the overall area 17 displayed by the touch-sensitive screen 2. Furthermore, the predetermined route 15 can be determined depending on the actual spatial conditions and obstacles present. Furthermore, by entering the predetermined route 15 via the interface, it is possible to determine the predetermined route 15 in a particularly user-friendly manner.

[0052] In particular, the Fig. The embodiment shown in Figure 4 is compatible with the first embodiment or comprises the elements of the first embodiment, but preferably without the, in particular active, joystick.

[0053] Fig. Figure 5 shows a schematic drawing of a second representation on the screen of a fourth embodiment of an operating device according to the invention. Fig. 5 shows a predetermined route 15, the total area 17, a current position of the floor cleaning machine 19, and a starting area 21. Here, the starting area 21 is shown as a trapezoid. However, any other shape of the starting area 21 is also possible. Fig. 5 a break point 23, a transport path 25, and a further current position 27. The predetermined route 15, the total area 17, the current position 19, the starting area 21, the break point 23, the transport path 25 and the further current position 27 are displayed by the touch-sensitive screen 2 as in Fig. 5 shown.

[0054] The predetermined route 15 is determined, for example, by teaching, wherein the teaching comprises driving the floor cleaning machine along the predetermined route 15. For example, the operator moves the floor cleaning machine along the route 15, and the corresponding sequence of positions in the overall area 17 is recorded by the floor cleaning machine or the operating device. This makes it possible to determine the predetermined route 15 by driving the floor cleaning machine along the predetermined route 15 without importing an environmental model into the floor cleaning machine. Alternatively, it is also possible to determine the predetermined route 15, for example, by entering spatial coordinates into the operating device, wherein the spatial coordinates again define different points along the predetermined route 15.For example, the spatial coordinates are entered by the operator using a stylus to draw or paint the predetermined route 15 into the overall area 17 displayed by the touch-sensitive screen 2. Furthermore, the predetermined route 15 can be determined depending on the actual spatial conditions and obstacles present. Furthermore, by entering the predetermined route 15 via the interface, it is possible to determine the predetermined route 15 in a particularly user-friendly manner.

[0055] In the Fig. In the embodiment shown in Figure 5, the starting area 21 is displayed when an autonomous process of the floor cleaning machine is interrupted. The starting area 21 is displayed as long as the floor cleaning machine has not reached the starting area 21. This is helpful, for example, if the operator moves the floor cleaning machine toward the starting area 21. Preferably, the starting area 21 is displayed as long as the floor cleaning machine has not reached a predetermined orientation in the overall area 17, preferably in the starting area 21.

[0056] The Fig. The predetermined route 15 shown in Figure 5 is provided, for example, for an autonomous process of the floor cleaning machine. During the autonomous process, the floor cleaning machine travels along the predetermined route 15. For example, if an obstacle is located on the predetermined route 15, the floor cleaning machine may leave the predetermined route 15 and interrupt the autonomous process. Alternatively, the operator can also interrupt the autonomous process. At the point on the predetermined route 15 at which the floor cleaning machine leaves the predetermined route 15, an interruption point 23 is defined and stored, for example, in the operating device 1 using spatial coordinates. In other words, the autonomous process of the floor cleaning machine along the predetermined route 15 is interrupted at the interruption point 23.If the autonomous process has been interrupted, the floor cleaning machine is no longer at a point along the predetermined route 15, but at another current position 27, as shown in . Fig. 5 shows an example of where the floor cleaning machine has, for example, interrupted its movement along the entire area or the operator has ended the interruption of the autonomous process. Fig. The operating device 1 shown in Figure 5 is designed in such a way that when the autonomous process of the floor cleaning machine is interrupted at the interruption point 23, a Fig. 5 is determined, wherein the transport path 25 extends between the interruption point 23 and the further current position 27 of the floor cleaning machine. The floor cleaning machine can thus be moved back along the transport path 25 to the predetermined route 15 or can move back independently or automatically along the transport path 25 to the predetermined route 15 during a further autonomous process and the autonomous process can be continued from the interruption point 23. The return movement is preferably carried out with manual assistance, preferably with the aid of an assistance system. Alternatively, the return movement can also take place autonomously or automatically by the floor cleaning machine traveling "backwards" along the transport path 25, ie in the direction of the predetermined route 15.Preferably, the floor cleaning machine returns along the recorded transport route 25 to the interruption point 23, either automatically or manually assisted, and continues its cleaning as planned.

[0057] Fig. 5 also shows the already in Fig. 1 and in the description in connection with Fig. 1 described three control elements 29, 29', 29", two information elements 31, 31' and two error elements 33, 33'.

[0058] In particular, the Fig. The embodiment shown in Figure 5 is compatible with the first embodiment or comprises the elements of the first embodiment, but preferably without the, in particular active, joystick.

[0059] Fig. 6 shows a schematic drawing of a third representation on the screen of a fourth embodiment of an operating device according to the invention. Fig. 6 shows the already in Fig. 2 and in the description in connection with Fig. 2 described zero point 3 and contact point 5. The Fig. Touch point 5 shown in Figure 6 can also be described as a freely positionable joystick. Fig. 6 which are already in Fig. 2 and in the description in connection with Fig. 2 described further origin 3', further tangency point 5', further vector 7', third projection 12 and third straight line 13. Furthermore, Fig. 6 which are already in Fig. 5 and in the description in connection with Fig. 5 described predetermined route 15, total area 17, current position 19 of the floor cleaning machine in the total area 17 and starting area 21 in the total area 17. In other words, the Fig. 6 is designed to display a path 15 with a starting zone 21 and a current robot position or floor cleaning machine position 19.

[0060] The predetermined route 15 is determined, for example, by teaching, wherein the teaching comprises driving the predetermined route 15 with the floor cleaning machine. For example, the operator moves the floor cleaning machine along the route 15, and the corresponding sequence of positions in the overall area 17 is recorded by the floor cleaning machine or the operating device 1. Alternatively, it is also possible to determine the predetermined route 15, for example, by entering spatial coordinates into the operating device, wherein the spatial coordinates again define different points along the predetermined route 15. For example, the spatial coordinates are entered by the operator using a stylus to draw or paint the predetermined route 15 into the overall area 17 displayed by the touch-sensitive screen 2.
