Description

Technical Field

[0001] The present invention relates to a construction robot, particularly for carrying out building construction work, comprising a manipulator and a switching interface arranged on the manipulator and configured for the detachable arrangement of at least one element, such as a tool and / or a component to be processed.

Background Art

[0002] In order to be able to perform complex construction tasks, often different tools are required. This is particularly true when the construction task is carried out using a construction robot. For example, in order to place a building element on the ceiling, first, a mark indicating the location where the building element is to be placed and / or the location where holes, for example, have to be drilled for fastening elements for fastening the building element, is applied to the ceiling by a marking tool. These holes can then be drilled using a drill tool. The necessary fastening elements can then be fitted using a mounting tool. Finally, the building element can be fastened to the fastening elements using a mounting tool.

[0003] In order to attach different elements, such as tools, to a construction robot and make them usable, the construction robot has a switching interface. The switching interface is configured for the detachable arrangement of at least one element, such as the tool to be used. The element to be attached may have a connecting portion complementary to the switching interface.

[0004] Due to the harsh environmental conditions at the construction site, particularly at a building construction site, such a switching interface is often subject to severe wear. Dust, dirt, etc. can also prevent the correct attachment of the element to the switching interface.

[0005] If an element is not properly attached to the switching interface, this poses a specific safety risk. Thus, for example, it is conceivable that the element may undesirably come off and cause damage when dropped. In the worst case, there is a possibility of injury.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The object of the present invention is thus to provide means and methods that enable the safe use of different elements by a construction robot.

Means for Solving the Problems

[0007] This object is achieved, in particular, by a construction robot for carrying out building construction work, comprising a manipulator, a switching interface arranged on the manipulator and configured for the detachable arrangement of at least one element, in particular a tool and / or a component to be processed, and a test device configured for quality testing of the switching interface.

[0008] The quality test may include, for example, tests for wear, function, and / or improper seating of a tool arranged on the switching interface.

[0009] Thus, it is possible to monitor the switching interface with respect to safety risks before, during, and / or after attaching and / or removing an element, for example a tool, onto / from the switching interface.

[0010] This makes it possible to avoid malfunctions of the construction robot and enables continuous testing of the tool interface so that the construction robot can achieve high system availability.

[0011] For example, before attaching the element, it may be checked whether there is dust or dirt on the switching interface. If such a safety risk is discovered, for example, a warning signal may be given, the safety risk may be eliminated, for example, the dirt may be removed, and / or other measures indicating and / or reducing the safety risk may be taken.

[0012] The "tool" may also include, for example, electric working tools such as machines for drilling, cutting, for example, saws or angle grinders, grinding, marking, measuring, etc. The tool may be particularly configured for processing rocks, for example, concrete.

[0013] Also, it is conceivable that the switching interface is configured such that other types of elements can also be attached to the switching interface. Thus, for example, it is conceivable that at least one component to be processed, for example, a ceiling element, a wall element, and / or an anchor, can be detachably arranged on the switching interface.

[0014] The switching interface is arranged on the manipulator. Depending on the element arranged on the switching interface, different construction tasks can be performed by the manipulator at different positions and / or in different orientations.

[0015] It is particularly advantageous to use such a construction robot for performing construction work at a construction site.

[0016] At an excavation site, it is possible to provide a barrier zone where people are not allowed to enter during the construction work. However, this possibility often does not exist or exists only in a very limited area at a building construction site. Also, at a building construction site, in many cases, a wider range of different elements, especially tools, are used than at an excavation site. In many cases, the elements need to be changed more frequently. The probability of coupling of element defects to the switching interface, and thus the need to prevent such safety risks, may therefore be higher at a building construction site than at an excavation site.

[0017] The construction robot may have at least one storage magazine configured to provide at least one element, in particular a tool and / or a component to be processed, for use by the construction robot.

[0018] Preferably, the storage magazine may be configured to provide an element for placement on the switching interface. For this purpose, the storage magazine may be arranged on the construction robot such that the switching interface can reach, in particular by means of a manipulator, an element held within the storage magazine. Preferably, the storage magazine may have several holding points. The holding points may then hold various tools and / or other elements required for the construction task, in particular components to be processed. In particular, after use of a tool, it is also conceivable that the tool that is no longer required is placed in one of the holding points of the storage magazine and removed from the switching interface.

[0019] The test device may comprise an optical test component. The optical test component may comprise an image capture unit, for example a color image camera, a black-and-white camera, and / or a 3D camera. The optical test component may be configured to detect the optical data of the switching interface. The optical test component may be arranged on the manipulator of the construction robot and / or on the moving platform.

[0020] The test device may also include a light source. Therefore, the recording conditions during the capture of optical data may be standardized. This may facilitate subsequent analysis of the optical data. It is also conceivable that the light source is configured to project at least one pattern onto the switching interface. Therefore, for example, a strip light image from which depth information can be derived may be captured.

[0021] It is also conceivable that an existing image capture unit is used as an optical test component. Therefore, for example, it is conceivable that a construction robot already has an image capture unit on a manipulator. Such an image capture unit may then also function as an optical test component of the test device. In this case, in particular, it may be advantageous if an optical deflection unit, for example a mirror, is arranged on the construction robot. The manipulator can then be positioned such that the image capture unit arranged thereon captures the optical data of the switching interface, in particular also arranged on the manipulator, via the mirror. Such multiple use of the same image capture unit may reduce the production costs of the construction robot. Also, the mass moved by the manipulator, and thus the associated inertia, can be kept low.

[0022] To analyze the optical data, the construction robot may have image processing logic configured to receive optical data, in particular image data, from the optical test component and to identify at least one quality characteristic of the switching interface from the optical data. The quality characteristic may, for example, correspond to the absence of sufficient dust, dirt, and / or wear phenomena such as break points or worn points. In general, the quality characteristic may correspond to a sufficient conformity of the optical data with previous and / or standardized optical data of the switching interface. In other words, the quality characteristic may be configured to indicate whether the switching interface has any deviation from the nominal value within the defined framework. The quality characteristic may here relate to the overall switching interface or simply to a partial area of the switching interface.

[0023] It is also conceivable that the image processing logic is formed at least partially on a remote computer system, in particular a cloud-based computer system. Subsequently, by collecting optical data from multiple construction robots, the analysis of the optical data can be continuously improved.

[0024] The construction robot may also be configured, as an alternative or in addition, to identify at least one quality characteristic of the storage magazine. For this purpose, the optical test component may also be configured to detect the optical data of the storage magazine. Accordingly, safety risks of the storage magazine due to dust, dirt, wear, elements erroneously held at the holding points, etc. may also be detectable. Particularly preferably, it may be provided to use the same image capture unit as the test component.

[0025] It is also conceivable that the test device includes a mechanical test component. This enables mechanical tests of the mechanical characteristics of the tool interface, such as force and / or pressure, in particular the maximum holding force, tensile stress, and / or contact pressure, expansion, distance, etc. during use. Such mechanical tests may be performed as an alternative to or in addition to the optical test. Here, it may be particularly advantageous that such tests using the mechanical test component can also test safety risks other than those possible with the optical test.

[0026] In particular, it is conceivable that the mechanical test component is configured to generate mechanical resistance such that the elements held within the storage magazine can only be removed against the resistance. The resistance may correspond to the minimum required holding force. Preferably, the resistance may exceed the gravitational force of the elements held within the storage magazine.

[0027] When different types of elements are held within the storage magazine, the resistance may be greater than the maximum gravitational force of all types of elements to be held. The resistance may in particular be at least twice the gravitational force.

[0028] This ensures that the element can be removed from the storage magazine only if the resistance force is compensated or overcompensated. The removal is performed such that the element is coupled to the switching interface, and then, when the switching interface is moved away from the storage magazine, for example by a manipulator, it is thus possible to ensure that the element is at least disposed on the switching interface by a maximum holding force corresponding at least to the resistance force.

[0029] Thus, a sufficiently firm seating of the element on the switching interface can be directly tested by a mechanical test component. The correct seating may be ensured especially before an element, for example a tool, is used to perform a construction task.

[0030] The mechanical test component may be formed by a part of the storage magazine, a part of the manipulator, and / or a part of the moving platform.

[0031] The resistance force may be generated magnetically. For this purpose, the test component may have a magnet. For example, the magnet may be disposed at a holding point of the storage magazine. The element may have a magnetizable region. While the element is held at the holding point, the magnetizable region may thus be attracted to the magnet by a magnetic force corresponding to the resistance force. In order to remove the element from the holding point, the magnetic force, thus the resistance force, and possibly the gravitational force of the element added thereto must be overcome at that time.

[0032] As an alternative or in addition, it is also conceivable that the test component has a latching mechanism. The latching mechanism may be configured such that latching is possible by applying a minimum release force. In that case, the minimum release force may form the above-mentioned resistance force.

[0033] Here, it is also preferable that the mechanical test component does not require further electrical components, and in particular does not require additional sensors, power supplies, or data lines for its supply. The switching interface can be tested automatically, particularly easily during the successful removal of the element, especially thereby.

[0034] As an alternative to or in addition to at least one of the test components described above, the test device may comprise an electrical test component. In particular, the electrical test component may be configured to detect the electrical quality characteristics of the switching interface. If the switching interface is configured for example for the transmission of electrical energy and / or data, the electrical test component may be configured to test the flow of current through the electrical lines that function for the transmission. Electrical resistance etc. may also be testable as quality characteristics.

[0035] Such electrical tests can also be easily repeated. For example, such electrical tests can continuously monitor whether the elements arranged on the switching interface are correctly electrically connected to the switching interface, particularly during the performance of construction tasks. This may then also indicate whether the entire element is correctly seated on the switching interface.

[0036] The invention further relates to a component system comprising elements, in particular tools and / or components, where the elements have connection parts configured for detachable connection to the switching interface of a construction robot of the type described above. Such a component system can be detachably arranged on the switching interface, for example, after testing the switching interface. For the possibility of testing, safety risks such as accidental detachment of the element from the switching interface can be reduced or avoided.

[0037] The component system and / or the construction robot may have a connection part testing device configured for quality testing of the connection part. Preferably, the connection part testing device comprises optical, electrical, and / or mechanical testing components, particularly of one of the types described above.

[0038] The scope of application of the present invention further includes a construction robot comprising a component system and a connection part testing device configured for quality testing of the connection part.

[0039] The quality characteristics of the connection part can be tested by the connection part testing device. Depending on the identified quality characteristics, countermeasures may be triggered as necessary. Here too, the safety risks during the use of the elements in the construction robot can be reduced.

[0040] The connection part testing device can be considered to be at least partially located on the manipulator, on the moving platform, and / or on the storage magazine. The connection part testing device corresponds to the testing device, is at least part of the testing device, and / or part of the testing device may also be used.

[0041] The present invention further relates to a method for arranging elements, particularly tools and / or components, on a switching interface of a construction robot of the type described above. The method comprises at least a) testing the quality characteristics of the component system and / or the switching interface by means of the connection part testing device and / or the testing device; b) arranging the component system on the switching interface.

[0042] The quality characteristics may indicate, for example, wear, dirt, degree of dust, and / or the presence or absence of elements.

[0043] The tests may be performed before, during, and / or after placement. In particular, multiple tests are also conceivable. Depending on the results of the tests, countermeasures can then be taken. For example, if an inappropriate attachment of an element to the switching interface is detected, the attachment trials may be repeated as long as necessary for the element to be correctly attached. Thus, here too, safety risks can be reduced.

[0044] The method can provide that at least one test is performed using a mechanical test component and at least one test is performed using an optical test component, as a result of which different types of safety risks and / or similar safety risks can be identified with a high probability and then mitigated. For example, first, the degree of wear of the tool interface can be optically tested, and then the seating of the element held on the tool interface can be mechanically tested.

[0045] It is also conceivable that the test is performed by an optical test component and the switching interface is moved to at least two different positions relative to the optical test component. In the subsequent analysis of the captured optical data, this can thereby facilitate the distinction between foreground data and background data. Generally, this may assist in the analysis of the optical data.

[0046] The method may also include that the quality characteristics of the storage magazine are, for example, indications of wear, abrasion, and / or presence or absence of tools and / or components.

[0047] In particular, it is conceivable to provide that the switching interface, the component system, and / or the storage magazine are tested using one and the same image capture unit.

[0048] A construction robot may be designed to perform construction work at a construction site. It may be installed to perform construction work on ceilings, walls, and / or floors. It may be configured for marking, drilling, cutting, chiseling, grinding, and / or fitting of building elements, and in particular, the corresponding tools may be detachably arranged thereon.

[0049] The construction robot has a manipulator. The construction robot may have a mobile platform. The manipulator may be arranged on the mobile platform.

[0050] The manipulator may be formed as a robotic arm. The manipulator may also have a lifting device. The lifting device may increase the size of the overall volume reachable by the manipulator. The manipulator may have at least 3 degrees of freedom. In particular, it may have at least 6 degrees of freedom.

[0051] The mobile platform may comprise a wheeled chassis and / or a tracked chassis. The mobile platform may have at least 2 degrees of freedom. The construction robot as a whole may have at least 10 degrees of freedom.

[0052] The image processing logic may be configured as a computer unit and / or be part of a computer unit. The computer unit may have a processor, a memory unit, and / or program code that may be executed by the processor. The processor may have one or more sub-processors. The program code may be configured to implement the described method on the construction robot.

[0053] Further features and advantages of the present invention will become apparent from the following detailed description of exemplary embodiments of the invention, and from the claims, with reference to the figures of the drawings which show details essential to the invention. The features shown are not necessarily to scale and are illustrated so as to clearly visualize the special features according to the invention. The various features can be implemented individually by themselves or collectively in any combination in variations of the invention.

[0054] Exemplary embodiments of the present invention are illustrated in schematic diagrams and will be described in detail in the following description.

Mode for Carrying Out the Invention

[0056] In the following description of the drawings, understanding of the present invention will be facilitated by using, in each case, the same reference numerals for identical or functionally corresponding elements.

[0057] FIG. 1 shows a construction robot 10 having a chassis 12 designed as a track chain chassis, a control space 16 formed within a housing 14, and a manipulator 18 disposed on the upper part of the housing 14. The manipulator includes a lift device 17 for vertical displacement and a multi-axis controllable arm 19.

[0058] An end effector 20 having a switching interface 21 is located at the free end of the arm 19.

[0059] A rock drilling tool having a tool 24, particularly a dust collecting device 26, is disposed on the switching interface 21.

[0060] Since the tool 24 is detachably disposed on the switching interface 21, the tool 24 has a connection portion 22. The switching interface 21 is configured for the detachable connection of the connection portion 22 and thus the tool 24.

[0061] The manipulator 10 may further comprise additional devices, such as a prism, a paint spraying device, a distance meter, position and / or orientation determination logic, a camera and / or similar devices, which, for reasons of simplification, are not shown in FIG. 1.

[0062] The construction robot 10 is designed to perform construction tasks, such as drilling operations on ceilings and walls, at a construction site, particularly at a building construction site.

[0063] The construction robot 10 further comprises a storage magazine 100. The storage magazine 100 has a plurality of deposit sites 102. Elements such as tools, for example the tool 24, and / or components required for the construction tasks to be performed may be placed at the deposit sites 102.

[0064] In addition to the manipulator 18 for performing construction tasks assigned to the construction robot 10, the construction robot 10 has a computer unit 27 arranged within a control space 16, in particular inside the housing 14. The computer unit 27 comprises a memory unit 28.

[0065] The computer unit 27 comprises executable program code. The program code may be stored in the memory unit 28 so as to be removable and executable. In particular, it may be configured to control the manipulator 18 such that one of the elements of the storage magazine 100 is removed from and / or placed on one of the deposit sites 102 of the storage magazine 100.

[0066] Furthermore, the construction robot 10 has a test device 104, in particular on the storage magazine 100. The test device 104 is configured for quality testing of the switching interface 21. For this purpose, it has an optical test component 106. The optical test component 106 comprises an image capture unit in the form of a color image camera. It may be oriented, for example, vertically upwards so that an image of the switching interface 21 can be captured when the end effector 20 reaches a position above the optical test component 106. Image processing logic 108, which is configured to compare one or more images with a nominal depiction of the switching interface and therefrom identify possible defects such as wear phenomena, dust, etc., is implemented in the computer unit 27, in particular by means of program code. The image processing logic 108 is part of the test device 104.

[0067] Figures 2 to 7, which are described below, show components of an alternative embodiment. Unless otherwise stated, these components may be used on the construction robot 10 described above as an alternative to their corresponding components. In particular, it is conceivable to use different types of alternative components described below in combination with the construction robot 10.

[0068] Figures 2 and 3 schematically show a storage magazine 100 having a deposit site 102.

[0069] An element, in particular a tool 24, is arranged at the deposit site 102.

[0070] The tool 24 has a connection part 22 for a detachable connection to a switching interface 21 arranged on the end effector 20 of the manipulator 18. The connection part 22 has, for example, a magnetizable plate made of magnetizable steel.

[0071] The element, i.e., the tool 24, and the connection part 22 form a component system 50.

[0072] A mechanical test component 106a is arranged on the storage magazine 100. The mechanical test component 106a has a magnet 107. The magnet 107 generates a resistance force FW, which is directed downward in the case shown in FIGS. 2 and 3 and supplements the gravitational force FG to hold the tool 24 at the deposit site 102. In order to lift the tool 24, the manipulator 18 must therefore apply a release force FL corresponding to at least the sum of the resistance force FW and the gravitational force FG and opposing the result of these two forces FW, FG. The switching interface 21 can transmit at least the necessary release force if the element, i.e., the tool 24, is correctly arranged on the switching interface 21, so that, when properly arranged, the tool can be successfully removed from the deposit site 102.

[0073] When the end effector 20 is moved vertically upward and at least the release force FL is generated there, the tool 24 or the component system 50 can thus be removed from the deposit site 102.

[0074] Figure 3 shows a situation corresponding to Figure 2, but with the difference that the switching interface 21 is contaminated with dust 110. The tool 24 can therefore not be properly connected to the switching interface 21 via the connection part 22. In particular, the required release force FL can no longer be transmitted to the connection part 22 via the switching interface 21.

[0075] When the end effector 20 is moved vertically upwards, the connection part 22 detaches from the tool interface 21. The tool 24 or the component system 50 can therefore not be removed from the deposit site 102.

[0076] The tool 24 therefore remains at the deposit site 102, thereby further reducing or even avoiding safety risks due to accidental detachment of the connection part 22 from the switching interface 21, for example during the performance of a construction task.

[0077] Figures 4 and 5 both show plan views of the connection part 22 (Figure 4) and the switching interface 21 (Figure 5), both showing signs of wear. For clarity, the areas affected by wear in Figures 4 and 5 are highlighted with ellipses.

[0078] Such wear can be identified by an optical test component, and an exemplary embodiment thereof will be described in more detail below.

[0079] Figure 6 shows a manipulator 18 having an end effector 20 on which the switching interface 21 is also formed. The test device 104 is arranged on a storage magazine 100 having a plurality of deposit sites 102.

[0080] The test device 104 has an optical test component 106. The optical test component 106 comprises, among other things, a color image camera.

[0081] Figure 6 schematically shows the field of view 112 of the optical test component 106. At the position of the manipulator 18 shown in Figure 6, the optical test component 106 may thus capture an image of the switching interface 21. These may be analyzed in the image processing logic of the test apparatus 104, for example as described above, so as to identify any safety risks.

[0082] Figure 7 shows a further manipulator 18 having an end effector 20 on which not only the switching interface 21 but also a further optical test component 106 corresponding to the optical test component 106 described above with reference to Figure 6 may be arranged.

[0083] The optical test component 106 comprises a color image camera.

[0084] At the position of the manipulator 18 shown in Figure 7, the field of view 112 of the optical test component 106 includes the connection portion 22 of the tool 24 located at the deposit site 102.

[0085] The connection portion test apparatus 114 is formed by the optical test component 106 together with the computer unit 27 (see Figure 1). For this purpose, the computer unit 27 is configured to analyze the image provided by the optical test component 106 with respect to the displacement of the connection portion 22 from the nominal connection portion, thereby identifying any safety risks in the connection of the connection portion 22 to the switching interface 21.

[0086] The tool 24 and its connection portion 22 thus form the component system 50.

[0087] Figure 8 shows a method 1000 for arranging a component system on the switching interface of a construction robot of the type described above.

[0088] Method 1000 will be described in more detail using the reference signs introduced above for the components of the construction robot 10. For example, the construction robot 10 forming the basis of the description has a test device 102 with a mechanical test component 106a according to FIGS. 2 and 3, and a connection part test device 114 with an optical test component 106 according to FIG. 7.

[0089] In a first method step 1010, the connection part 22 of the tool 24, and thus also the connection part 22 of the component system 50, is tested for deviations from the nominal. In particular, the connection part 22 is tested for quality characteristics regarding the presence of dirt such as dust. In case of a defect, a defect correction 1040 is carried out.

[0090] First, in a coupling step 1020, the switching interface 21 is moved by the manipulator 18 to the connection part 22 of the component system 50. The switching interface 21 is coupled to the connection part 22 and is thus arranged on the component system 50, in particular on the tool 24.

[0091] In a subsequent test step 1030, it is tested whether the tool 24 is correctly coupled. For this purpose, the manipulator 18, and thus the switching interface 21, is moved away from the storage magazine 100. During this process, a release force FL is determined.

[0092] If the release force FL is less than the minimum release force expected according to the resistance force FW and the type of tool, this indicates an incorrect coupling to the connection part 22 or the switching interface 21 of the tool 24. Also in this case, a defect correction 1040 is carried out.

[0093] The defect correction 1040 may consist of a plurality of steps. In particular, it may include a first defect treatment that attempts to clean the switching interface 21 or the connection part 22 first, by means of a cleaning device, for example a brush roller.

[0094] If a subsequent test fails again, a second malfunction handling may be provided, during which an instruction signal is sent to the user of the construction robot 10 to manually correct the malfunction.

[0095] For example, for documentation purposes, it may be considered to store at least one of the test results in a memory and / or to send it to a further computer unit, for example a cloud-based computer unit, for storage and / or further processing there.

[0096] Performing further tests may also be considered. For example, an electrical test of the electrical resistance may be performed to check whether one or more electrical connections between the switching interface 21 and the connection part 22 are properly made.

[0097] If the two tests in steps 1020 and 1030 are successful, at the performance stage 1050, the desired construction task is performed by the tool 24 located on the tool interface 20.

[0098] For example, one or more holes may be drilled by the tool 24 configured as a rock drill machine.
