Description

[0001] The invention relates to the use of electric power tools by a construction robot.

[0002] In order to be able to employ the construction robot as flexibly and cost-effectively as possible, it is desirable that the construction robot can be used together with different types of electric power tools.

[0003] Especially if power tools that can be used in other ways can also be used effortlessly with construction robots, lower operating costs can be expected.

[0004] It is therefore an object of the present invention to provide a power tool which enables both manual use and automated use by means of a construction robot, with switching between these being as effortless as possible, and to supply such a power tool to a construction robot.

[0005] This object is achieved by an electric power tool, in particular a handheld power tool, which includes a motor and a tool accessory, which is used to hold a tool, such as a drilling tool, a cutting tool and / or a grinding tool, wherein the motor is configured to drive the tool accessory, and wherein the power tool can be remotely controlled electrically and / or by radio.

[0006] This is based on the idea that although it is in principle conceivable to use a power tool together with a construction robot, in which one or more actuating elements of the power tool are mechanically influenced, for example by means of a hydraulic and / or pneumatic system, so that the power tool can be opened and closed, for example by the construction robot,

[0007] However, such a hydraulic system or such a pneumatic system would each require extensive modifications at the construction robot. Additionally, modifications would need to be made specifically for each power tool.

[0008] In contrast, the power tool presented herein allows it to be remotely controlled by a construction robot. Remote control can be performed via radio and / or via an electrical connection. A large number of additional components for a mechanical control unit for the power tool, in particular for a mechanical control unit specifically adapted for the power tool, are not required.

[0009] The power tool can thus be used by the construction robot without much effort and thus particularly cost-effectively.

[0010] The power tool is still easy to use manually. In particular, neither electrical nor radio-based remote control prevents manual manipulation of the power tool.

[0011] This problem-free possibility of manual use can make the power tool more widely distributed. In particular, the power tool can be a handheld power tool. Economies of scale can therefore be used, as a result of which the production costs of the power tool can be further reduced.

[0012] It is conceivable that the power tool has a data interface, wherein the power tool can preferably be remotely controlled via the data interface.

[0013] For example, the data interface may be configured to transmit control commands, characteristic data and / or status data.

[0014] For example, the operating mode and / or operating state of the power tool may be controlled.

[0015] In particular, the power tool may be switched on and / or off by remote control.

[0016] It is also conceivable that at least one of the work output, the direction of rotation, the rotation frequency, the torque or the impact frequency can be set by remote control.

[0017] In the case of a power tool with an impact function, it may be advantageous if the impact function can also be set by remote control. Thus, for example, to drill a hole in concrete, the construction robot can first start drilling with the impact function deactivated and later enable the impact function in order to minimize the risk of undesired chipping of the hole edge.

[0018] The power tool can be configured to supply, for example, at least one piece of identification data, a performance capability, such as a maximum available impact energy and / or a maximum available work output as characteristic data that can be called up, in particular via a data interface.

[0019] It is also conceivable that the power tool is configured to supply at least one operating state of the power tool, such as at least one rotational speed, temperature, measured value of component wear, etc., so that the power tool can be called, in particular via a data interface.

[0020] For this purpose, it is advantageous if the data interface has a bidirectional design. Thus, for example, control commands can be transmitted from the construction robot to the power tool and characteristic and / or status data can be transmitted from the power tool to the construction robot. It is also conceivable herein that control commands and / or characteristic and / or status data can also be transmitted alternatively or additionally in the respective opposite direction.

[0021] The power tool may have at least one protective device for protecting a user during manual use of the power tool.

[0022] The protective device can be, for example, a start lock, in particular a restart lock, which prevents the motor from starting merely by applying a supply voltage, in particular without additional actuation of an actuating element.

[0023] The power tool may have an actuating element by means of which the protective device is implemented. The actuating element may be an electrical switch (e.g. a rotary switch, a sliding switch or a rocker switch), an electrical button (e.g. a push button), or an actuator (e.g. a knob (e.g. a potentiometer) or a slider).

[0024] The power tool may also have a sensor. The sensor may be configured to detect a protection situation. The protection situation may correspond to a situation in which a protection device will be activated.

[0025] The sensor may be, for example, a proximity sensor, an acceleration sensor, a rotation sensor, a translation sensor, a current and / or voltage sensor.

[0026] The protection device can be configured to reduce or stop vibration, work output, rotational frequency, speed and / or torque so that when an event monitored by the protection device occurs, the user is intuitively informed of the occurrence of the monitored event and / or is immediately protected from its consequences.

[0027] The protection device may also be configured to hinder operation of the motor. Thus, use of the power tool may be prevented until the monitored event no longer exists. Thus, injury to the user may be preventively avoided.

[0028] The protection device can be deactivatable, in particular activatable and deactivatable. In particular, it can be deactivated by remote control, in particular can be activated and deactivated by remote control.

[0029] Power tools sometimes feature protective devices that are arranged for safe use by human users. For example, a speed controller may be arranged so that the speed can only be set after the speed controller has been pressed. Inadvertent operating errors in manual use can thus be avoided.

[0030] Another example of a protective device is also a blockage detection unit (for example a unit which detects that the drill bit of a power drill is stuck in the substrate) and / or an automatic torque control unit, in each case in combination with an automatic shut-off or at least with an automatic speed reduction.

[0031] Another example of a protective device is a restart lock, which prevents the motor from starting if the corresponding switch or control is not pressed or generally manually actuated. Such a restart lock is conceivable in particular in the case of a cordless power tool in order to avoid an undesired start when charging the battery of the power tool.

[0032] The protective device may also be a vibration damping unit, in particular for reducing vibrations of a handle section of the power tool.

[0033] It is also conceivable that the protective device is configured to cause the user to assume a specific posture. For example, the power tool can have two actuating elements arranged at different points, so that the motor is only started when both actuating elements are actuated simultaneously. It can thus be ensured that, for example, the user holds the power tool in both hands at a defined point and thus, for example, an injury to one of their hands can be ruled out.

[0034] While such protective devices may facilitate and / or protect manual use by a human user, they may sometimes make use by a construction robot quite difficult or even impossible.

[0035] For example, in the last mentioned example, the construction robot would have to be configured to mimic a specific posture in order to be able to use the power tool. Otherwise, the construction robot would not be able to use the power tool.

[0036] In this case, if the protective device of the power tool is deactivatable, in particular by remote control, the range of power tools that can be used by the construction robot can be expanded. If the protective device is also activatable, in particular by a remote controller, the protective device can be deactivated if it hinders the use by the construction robot and, as a precaution, reactivated in other situations.

[0037] The power tool may be configured such that deactivation and / or activation of the protection device takes place actively, in particular by communicating corresponding control commands.

[0038] It is also conceivable that the power tool is configured for passive deactivation and / or activation, for example by the power tool automatically detecting whether the power tool is being used manually or in an automated manner by a construction robot.

[0039] The power tool may have a battery interface for connecting a battery. Thus, it can be operated without a cord.

[0040] At least a part of the data interface can be integrated into the battery interface. Remote control can then be performed via the data interface.

[0041] A system is also presented, which includes a construction robot and an electric power tool, wherein the electric power tool is arranged on an end effector of the construction robot, wherein the construction robot is configured to activate and / or deactivate a protection device of the power tool. The power tool may correspond to the above-mentioned power tool, wherein the power tool has the protection device in any case.

[0042] With such a system, the construction robot can deactivate the protective device before using the power tool so that the protective device cannot further hinder actual use.

[0043] An interface adapter for connecting an electric power tool to an end effector of a construction robot is also presented, wherein the interface adapter has a connection point for connecting to the power tool, the connection point being designed such that the connection point is complementary to a standard battery interface of the power tool.

[0044] The present invention is based on the idea that electric power tools, in particular battery-powered power tools, for example battery-powered hand-held power tools (such as hand-held power drills, in particular masonry power drills, nail guns, power grinding tools, power saws, power hammers, etc.) usually have an energy supply interface, in particular an energy supply interface of uniform design, which is standardized at least on many types of power tools, for example from the same manufacturer.

[0045] The battery-powered power tool therefore has a standard battery interface, by means of which a battery that complies with the relevant standards can be mounted on the power tool. Here, the standard battery interface can perform at least two functions: First, the standard battery interface can be designed to securely hold the battery on the power tool. For this purpose, the standard battery interface can, for example, have a latching mechanism.

[0046] Secondly, the standard battery interface can be configured to transmit operating energy. Here, the operating energy can be unidirectionally transmittable, in particular from the battery to the power tool. The operating energy can also be bidirectionally transmittable, for example for the purpose of recharging the battery by energy recovery. The standard battery interface can have other additional functions. In particular, the standard battery interface can also be configured for signal transmission between the battery and the power tool. The signal transmission can also be unidirectional or bidirectional.

[0047] Thus, the interface adapter can be mounted on one side on the end effector of a construction robot. By means of the connection points, the interface adapter can be mounted on the other side on a standard battery interface of a power tool, in particular instead of a conventional battery. Thus, the power tool can be mounted on the end effector via the interface adapter. This is possible for all power tools having the same standard battery interface and thus in general for a large number of different types of power tools, in particular power tools that can be powered by batteries.

[0048] Typically, the standard battery interface is designed for fastening the battery without tools and / or for removing the battery without tools. Thus, the power tool can also be easily and quickly separated from the end effector again, in particular without the need to use tools.

[0049] Because such a standard battery interface typically has a latching mechanism for securing the battery, it can still be ensured that the power tool is securely retained on the end effector.

[0050] The construction robot may be configured to perform work on walls and / or ceilings, particularly in building construction sites, civil engineering construction sites, and / or industrial facilities.

[0051] It is conceivable that the interface adapter has a power tool signal interface and a construction robot signal interface for transmitting at least one signal between the construction robot and the power tool. Therefore, in addition to the mechanical connection between the construction robot and the power tool, a signal transmission connection between the two devices can also be generated by means of the interface adapter.

[0052] For example, a signal may be understood to mean at least one control signal and / or at least one sensor signal.

[0053] The transmission can be unidirectional or bidirectional.

[0054] The interface adapter can also have an additional battery interface and / or an additional signal interface, by means of which the battery can be attached to the interface adapter.

[0055] The power tool signal interface and the construction robot signal interface can also be configured to transmit operating energy. Therefore, electrical operating energy can be supplied to the power tool. Here, operating energy can be understood to refer to the energy basically required to operate the power tool in a conventional manner. Correspondingly, these signal interfaces can be configured to transmit instantaneous electrical power of at least 0.1kW, for example at least 1kW.

[0056] If the interface adapter has an additional battery interface and / or an additional signal interface, operating energy can also be transmitted to the battery arranged at this or these interfaces, for example for the purpose of charging the battery. Operating energy can also be transmitted from the battery, for example in order to be able to briefly provide a particularly increased electrical power level to the power tool.

[0057] At least a portion of the power tool signal interface may be formed as part of the connection point. For example, the power tool signal interface may use or at least co-use one or more electrical contacts of the connection point.

[0058] Thus, the sensor signal can be transmitted via the connection point.

[0059] It is also conceivable to provide a separate control interface for transmitting control signals, for example for switching the power tool on / off or for controlling at least one operating parameter (e.g. rotational speed). This may be convenient, for example, in the case of a power tool in which at least one function required for controlling the power tool cannot be controlled via a standard battery interface.

[0060] The interface adapter may also include a signal converter configured to convert a signal received at one of the signal interfaces, for example to modify the level, impedance or signal encoding of the signal, and output the signal at the other signal interface.

[0061] It is particularly conceivable that the signal converter is configured to convert sensor signals and / or control signals that have been output by the construction robot in "robot language" into a signal form that can be processed by the power tool. Alternatively or additionally, it is also conceivable that the signal converter is configured to convert sensor signals and / or control signals from the power tool into a signal form that can be processed by the construction robot.

[0062] Thus, it is possible to enable the construction robot to control different types of power tools using signals which are in each case independent of the power tool, or conversely to receive signals from different power tools.

[0063] Here, the signals can be transmitted on a half-duplex or full-duplex basis. The signals can be differential or ground-referenced.

[0064] Alternatively or additionally, it is also possible for the signal converter to convert the operating energy to be transmitted.

[0065] The signal interface may be an electrical interface. For example, provision may be made for modulating at least one signal onto the operating energy supply.

[0066] Alternatively or additionally, it is also conceivable that at least one of the signal interfaces is configured for wireless data transmission, in particular for optical and / or radio-based data transmission. For example, it is convenient that the wireless data transmission utilizes a low-energy radio standard. The connection can exhibit automatic coupling. In particular, inductive, microwave-based and / or optical (e.g. infrared-based) data transmission is conceivable. Such wireless data transmission is reliable even in very dusty environments (such as those typically encountered on construction sites). Moreover, such data transmission does not require any mechanical interaction for coupling purposes, thereby simplifying coupling and decoupling.

[0067] The interface adapter may also have a control unit which is configured to generate a control signal and to output the control signal to at least one of the two signal interfaces.

[0068] For this purpose, the interface adapter can have a microcontroller. The microcontroller can have a memory, a microprocessor and / or a program code that can be executed on the microprocessor and stored in the memory.

[0069] By means of such a control unit, the interface adapter can control the attached power tool and / or construction robot. For example, the control unit, in particular the program code, can be configured to detect faults, such as incorrect arrangement of the power tool on the interface adapter. Then, the control unit can be configured to transmit a corresponding signal to the construction robot via the construction robot signal interface. For example, the construction robot can start a fault handling routine in response to the signal. Another example is that the control unit of the power tool transmits a query signal via the power tool signal interface. The power tool can then send back a response signal. For example, in this way, the control unit can query the parameters of the power tool and / or set parameters.

[0070] The control unit can, for example, be configured to query the type or identifier of the power tool. The control unit can then be configured to set parameters of the control unit itself, such as signal converter parameters related to the conversion, as a function of the type or identifier, and / or to transmit parameters (in this case the type or identifier) ​​to the construction robot via the construction robot signal interface. Similarly, it is also conceivable that the control unit transmits a query signal to the construction robot and receives a response signal from it. Based on the response signal, the control unit can set parameters of the control unit itself and / or of the power tool.

[0071] In particular, the control unit can be configured to receive at least one sensor signal from the power tool signal interface and / or from the construction robot signal interface. The sensor signal can then be used by the control unit for control purposes. For example, if the sensor signal is related to the vibration caused by the power tool, if a specific vibration level of the power tool is exceeded, the control unit can transmit a control signal for operating at a lower power and / or for adopting a standby mode via the power tool signal interface. Thus, the construction robot can be protected from mechanical overload.

[0072] Alternatively or additionally, further sensor signals are also conceivable, for example sensor signals indicating at least one characteristic variable of the power tool and / or the construction robot, for example sensor signals regarding vibrations, current, force, temperature, power tool type, situation and / or position, travel distance, feed movement and / or the like.

[0073] If a battery interface is available, the sensor signal may also be related to a battery connected to the battery interface.

[0074] It is also conceivable that the sensor signal indicates an operating mode and / or that the control unit sets an operating mode, in particular an operating mode of the power tool.

[0075] For example, the behavior of the power tool can thus be adapted depending on whether a battery or an interface adapter is attached. For example, a trigger can be set or ignored depending on the detected state. For example, a wake-up mode can be triggered. An identification code can also be transmitted and / or received by the control unit.

[0076] If the interface adapter has at least one damping element for damping vibrations acting on the interface adapter, the durability of the construction robot and / or the precision with which the construction work can be performed can be increased. The damping element can be configured for passive damping and / or active damping.

[0077] The interface adapter itself may have at least one sensor. The sensor may be, for example, a force sensor and / or a pressure sensor. The interface adapter may then be configured to measure contact forces, tension forces and / or similar forces, etc.

[0078] A system is also presented, which includes a construction robot, an interface adapter of the type described above and / or below, and an electric power tool, wherein the electric power tool has a standard battery interface and wherein the standard battery interface of the power tool is arranged at a connection point of the interface adapter.

[0079] The power tool may in particular have one or more of the features of the power tool described above. In particular, the power tool may comprise a protective device.

[0080] It is conceivable that the system also includes additional adapter parts. Thus, there may be power tool-specific and / or construction robot-specific adapter parts. These adapter parts can be used to adapt the power tool and / or the construction robot to the interface adapter.

[0081] The power tool can be configured to detect, in particular via its standard battery interface, whether a battery or an interface adapter is installed at the standard battery interface. It can also be configured to detect whether any element is arranged at the standard battery interface, and if so, specifically what type of element the element is. Thus, the power tool can be configured, for example, to utilize energy recovery when a battery is installed, and not to utilize energy recovery when an interface adapter is installed.

[0082] It is also conceivable to modify the power tool. Thus, it is conceivable that the handle insert of the power tool is at least partially replaced by a part of the interface adapter or the interface adapter as a whole.

[0083] The construction robot can be designed for carrying out construction work at a building construction site and / or a civil engineering construction site and / or in particular steel-based industrial facilities, for example on an oil platform. The construction robot can be configured to perform construction work on ceilings, walls and / or floors. The construction robot can be designed for drilling, cutting, chiseling, grinding and / or setting structural elements. The construction robot can have one or more power tools. The power tools can include cutting tools, grinding tools and / or setting tools. It is also conceivable that the end effector and / or the power tool are designed for marking. For example, the end effector can have a paint spraying device. Measuring tools (e.g. rangefinders) can also be arranged alternatively or additionally on the end effector.

[0084] The interface adapter can be mounted on the end effector. The power tool and / or the measuring tool can then be mounted on the interface adapter. The construction robot, in particular the end effector, can in principle also include a plurality of power tools and / or measuring tools.

[0085] The construction robot may have a manipulator. The manipulator may be designed as a robot arm. The manipulator may also have a lifting device. The lifting device may increase the size of the total volume that the manipulator can reach. The manipulator may have at least three degrees of freedom. In particular, the manipulator may have at least six degrees of freedom.

[0086] The construction robot may also have a mobile platform. The mobile platform may include a wheeled chassis and / or a crawler chain chassis. The mobile platform may have at least two degrees of freedom. The construction robot may have a total of at least ten degrees of freedom. Alternatively, it is also conceivable that the mobile platform is a flying platform or includes a flying platform. For example, the construction robot may also be designed as a flying drone.

[0087] It is also conceivable that the construction robot can be activated via an interface adapter.

[0088] It is also contemplated that the power tool may be activated and / or deactivated via the connection point.

[0089] Further features and advantages of the invention emerge from the following detailed description of exemplary embodiments of the invention with reference to the accompanying drawings, which show details essential to the invention, and from the claims. The features shown therein are not necessarily to be regarded as true to scale, but are presented in such a way that the special features according to the invention can be clearly visualized. In variants of the invention, the various features may be realized individually by themselves or collectively in any combination.

[0090] Exemplary embodiments of the invention are illustrated in the schematic drawings and explained in detail in the following description.

[0091] In the attached picture:

[0092] Figure 1 A power tool is shown;

[0093] Figure 2 The interface adapter is shown in side view;

[0094] Figure 3 A modified power tool having a power tool adapter portion is shown in side view;

[0095] Figure 4 showing in perspective the power tool during modification of the power tool;

[0096] Figure 5 showing in side view the modified power tool with the interface adapter installed;

[0097] Figure 6 An interior view of a portion of an interface adapter with a control unit is shown in perspective;

[0098] Figure 7 A system including a construction robot, an interface adapter, and a power tool is shown; and

[0099] Figure 8 A simplified block diagram is shown.

[0100] In the following description of the figures, the understanding of the invention is facilitated by the use of the same reference symbols in each case for identical or functionally corresponding elements.

[0101] Figure 1 There is shown a power tool 10. The power tool 10 is a battery powered masonry drill.

[0102] It has a base body 12, from one end of which a tool accessory 14 protrudes. At the other end, it has a handle 16. An actuating element 17 is located on the handle 16, which can be used to manually control the power tool 10. In particular, the actuating element 17 can be used to start and stop the drilling operation or to adjust the rotation speed.

[0103] Furthermore, it has a standard battery interface 18. The standard battery interface 18 is designed to receive a battery. It is used in particular to fix the battery to the power tool 10, to transmit operating energy between the battery and the power tool 10, and to transmit signals between them.

[0104] For example, Figure 1 A battery 20 is shown, which is Figure 1 In the state shown, the standard battery interface 18 has been pushed approximately halfway into position.

[0105] In order to enable the battery 20 to be mounted on the standard battery interface 18 , the battery 20 has a connection point 22 which is designed to complement the standard battery interface 18 .

[0106] In order to completely install the battery 20 , the battery must be pushed further onto the standard battery interface 18 in the direction of the arrow 24 . In order to completely remove the battery, the battery must be pushed further away from the standard battery interface 18 in the opposite direction of the arrow 24 .

[0107] Therefore, installation and removal can be performed without using tools.

[0108] Figure 2 An interface adapter 100 for connecting an electric power tool to an end effector of a construction robot is shown.

[0109] The interface adapter has a function of connecting to a power tool (e.g., according to Figure 1 A power tool connection point 110 of a power tool 10).

[0110] The power tool connection point 110 has a power tool connection portion 112 that is designed to connect to a standard battery interface 18 (see Figure 1 ) is complementary. Therefore, the power tool connection point 110 as a whole is also designed to be complementary to the standard battery interface 18.

[0111] The power tool connection part 112 has electrical contacts 114. If the power tool 10 has been attached to the power tool connection point 110, operating energy (particularly for the purpose of operating the power tool 10) can be transmitted via the contacts 114. For example, a current with a voltage of about 22V DC can be provided for transmission as operating energy.

[0112] By modulating the signal onto the operating energy to be transmitted, signals can also be transmitted bidirectionally from and / or to the power tool 10 via the contact 114. In this respect, the contact 114 is combined with the rest of the power tool connection point 110 to simultaneously form a power tool signal interface 116.

[0113] The interface adapter 100 also has a construction robot connection point 118. This is used to connect to the end effector of the construction robot, for example, to the following combined Figure 7 The construction robot is further described in more detail.

[0114] In particular, for releasably fastening the interface adapter 100 to the end effector, the construction robot connection point 118 has a bracket 120 which is in particular pneumatically actuatable.

[0115] The power tool connection point 110 may be pushed onto the damping element 122 such that the damping element 122 is located substantially between the power tool connection point 110 and the construction robot connection point 118. The damping element serves to damp vibrations during operation of the power tool 10 which may originate from the power tool, for example.

[0116] Through the electrical contact socket 124, operating energy can be transmitted between the attached construction robot and the interface adapter 100. For example, the operating energy can be transmitted in the form of an electric current having a voltage of 48V.

[0117] By modulation, signals can also be transmitted, in particular bidirectionally, between the interface adapter 100 and the construction robot via the contact socket 124. In this respect, the contact socket 124 is combined with the rest of the construction robot connection point 118 and simultaneously forms a construction robot signal interface 126.

[0118] Thus, signals may be communicated between the power tool 10 and the construction robot via the power tool signal interface 116 and via the construction robot signal interface 126 .

[0119] Interface adapter 100 also has a control unit 128 .

[0120] The power tool connection point 110 is electrically connected to the rest of the interface adapter 100 , in particular to the control unit 128 , via a connecting lead 130 .

[0121] Therefore, operating energy can also be transmitted between the construction robot and the power tool 10 via the power tool signal interface 116 and the construction robot signal interface 126 .

[0122] Figure 3 The power tool 10 is shown in a modified form. Figure 1 Compared to the design in , the handle 16 with the actuating element 17 and the battery 20 have been removed.

[0123] The manually operable actuating element 17 has been replaced by a control connector 26 , so that the control function of the actuating element 17 is now electronically controllable.

[0124] The power tool adapter portion 28 has been mounted to the power tool 10 in place of the handle 16 .

[0125] The standard battery interface 18 has been mounted on the outside of the power tool adapter portion 28 in a pivoted position.

[0126] Figure 4 The power tool 10 is shown in a perspective view during modification of the power tool. In particular, the standard battery interface 18 can be seen, which is connected to the power tool 10 in the same manner as the power tool 10. Figure 4In a subsequent step corresponding to the illustration in FIG. 1 , the standard battery interface will be pivoted counterclockwise by approximately 90° onto the already installed power tool adapter portion 28 .

[0127] Also visible are the mating contacts 30 which are formed on the standard battery interface 18 and are configured to mate with the contacts 114 (see Figure 2 ) to establish electrical contact.

[0128] Figure 5 Shown according to Figure 3 The modified power tool 10, according to Figure 2 The interface adapter 100 is already installed on the power tool.

[0129] For this purpose, the damping element 122 has been mounted (eg, threaded) to the power tool adapter part 28 .

[0130] The power tool connection point 110 is located on the standard battery interface 18 .

[0131] The control connector 26 is connected to a control connection socket 132 of the control unit 128 .

[0132] Figure 6 An interior view of the control unit 128 is shown in a perspective view.

[0133] The control unit 128 comprises an electronic circuit 134 which has in particular a microcontroller 136. The microcontroller 136 has a microprocessor 138 and a memory 140. In the memory 140 a program code 142 which can be executed on the microprocessor 138 is stored.

[0134] The control unit 128 is configured to convert a signal received at one of the signal interfaces, in particular by means of the program code 142. In particular, the control unit is configured to convert a signal received at the robot signal interface 144, which has been modulated onto a direct current having a voltage of 48 V, into a signal modulated onto a direct current having a voltage of 22 V, and output the signal at the power tool signal interface 116. Thus, the control unit 128 also forms the signal converter 144.

[0135] The control unit 128 is also configured to query the sensor signals 146 from the vibration sensor 148 through the program code 142. The control unit is also configured to, if at least one of the sensor signals 146 exceeds a threshold, generate a signal at the power tool signal interface 116 ( Figure 2 ) outputs a braking signal at . Based on the braking signal, the power tool 10 (designed as a masonry drill in the present exemplary embodiment) can, for example, reduce the rotational speed so that the vibrations caused by the power tool are also reduced.

[0136] Figure 7 A system 200 is shown. The system 200 includes a construction robot 210, an interface adapter 100, and an electric power tool 10.

[0137] The interface adapter 100 corresponds to the aforementioned Figure 2 , Figure 5 and Figure 6 An interface adapter 100 is described.

[0138] The power tool 10 corresponds to the Figure 1 , Figure 3 , Figure 4 and Figure 5 A power tool 10 is described.

[0139] The construction robot 210 has a mobile platform 214 equipped with a crawler chain chassis 212. A manipulator 216 is arranged on the mobile platform 214. The manipulator 216 has a lifting device 218, and a multi-axis arm 220 is mounted on the lifting device. The lifting device 218 can move the arm 220 in the vertical direction. The arm 220 has at least six degrees of freedom. Therefore, the end effector 222 arranged on the working end of the arm 220 can be oriented vertically and horizontally. Therefore, the construction robot 210 can perform construction work, especially drilling work, on ceilings, walls and / or floors using a power tool 10 designed as a masonry drill.

[0140] The interface adapter 100 is arranged on the end effector 222. Its construction robot signal interface 126 (see Figure 2 ) is connected to the corresponding signal output terminal of the construction robot 210.

[0141] In particular, the standard battery interface 18 of the power tool 10 (see Figure 2 ) is arranged at the power tool connection point 110 of the interface adapter 100 (see Figure 2 )superior.

[0142] Figure 8 A simplified block diagram of system 200 is shown. Figure 8 The illustration is limited in a simplified manner to the features explained in detail below. Unless otherwise stated, the elements explained in detail below correspond in each case to the corresponding elements described above.

[0143] The system 200 is shown to include a construction robot 210 and an electric power tool 10 .

[0144] As described above, the power tool 10 is connected to the construction robot 10 via the interface adapter 100 and the battery interface 18 .

[0145] The power tool 10 has a power tool control unit 32. The power tool control unit includes a power tool microcontroller 34 and a power tool memory 36. In the power tool memory 36, a power tool program code 38 is stored, which can be executed on the power tool microcontroller 34. The program code 38 and the power tool microcontroller 34 are configured as a whole to control the elements of the power tool 10.

[0146] In particular, the power tool control unit 32 is configured to control a motor 40 of the power tool. The motor 40 is configured to drive the tool accessory 14 (see Figure 1 ).

[0147] Data of the power tool 10 , in particular signals and operating data, can be transmitted bidirectionally between the construction robot 10 and the power tool via the data interface 31 . The data interface 31 is integrated into the battery interface 18 .

[0148] In particular, as also described above, the power tool 10 can be remotely controlled by the construction robot 100. To this end, control signals can be transmitted from the construction robot control unit 224 of the construction robot 10 to the power tool control unit 32 via the interface adapter 100 and the data interface 31.

[0149] The power tool 10 has a protection device 42 for protecting a user during manual use of the power tool 10. The protection device 42 includes a sensor 44.

[0150] The protection device 42 , in particular the sensor 44 , is configured to detect a blockage of a tool held in the tool accessory and to notify the power tool microcontroller 34 of this blockage by means of a blockage signal.

[0151] By means of the power tool program code 38, the power tool microcontroller 34 is in a manual operating mode enabled in a standard manner and is thereby configured to decelerate the motor 40 to a standstill when a blocking signal is received.

[0152] However, the construction robot control unit 224 can transmit a deactivation signal to the power tool microcontroller 34, so that the power tool microcontroller then switches to the automatic operation mode with the help of the power tool program code 38. In this automatic operation mode, the power tool microcontroller 34 does not respond to any blocking signal received from the protection device 42. Therefore, the protection device 42 can be deactivated by remote control.

[0153] The construction robot control unit 224 can similarly cause the power tool microcontroller 34 to switch back to the manual operation mode by means of the enabling signal. Therefore, the protection device 42 can also be enabled by remote control.

[0154] It is provided here that the construction robot control unit 224 deactivates and then reactivates the protective device 42 before carrying out the construction task (in this case before starting to drill into the stone).
