- the workpiece is preferably designed as a vehicle part to be machined and / or assembled, for example as a body component.
- the vehicle part can be transported on a conveyor belt through a vehicle production line. It is particularly preferred that the workpiece is transported continuously, in particular continuously, through the vehicle production line and that the assembly operation takes place during the transport.
- the robot arrangement comprises an industrial robot, which in particular comprises a robot arm.
- the industrial robot can, for example, be arranged in a stationary manner adjacent to the conveyor belt or can be moved on a corresponding conveyor device parallel to the conveyor belt.
- the robot arrangement optionally includes the workpiece and / or the conveyor belt.
- the industrial robot has a tool unit which is rotatably attached to the industrial robot.
- the tool unit can preferably be coupled and / or coupled to the robot arm in terms of signal technology and rotatably.
- the tool unit comprises a tool holder and a mounting device.
- the tool holder is designed as a tool socket and the mounting means as a screw.
- the assembly means is accommodated in an ideal assembly position in the tool holder.
- the ideal mounting position is given when the tool holder and the mounting means are arranged coaxially to one another and when the mounting means is in a defined receiving depth in the Tool holder is arranged.
- the robot arrangement comprises at least one force sensor.
- the at least one force sensor is designed to detect a differential force which acts on the tool unit during and / or during assembly, in particular between the tool holder and the assembly means.
- the robot arrangement comprises at least one torque sensor for detecting a torque with which the assembly means is introduced, in particular screwed, into the bore in the workpiece.
- the at least one force sensor and optionally additionally the at least one torque sensor is integrated in at least one joint of the industrial robot, preferably the robot arm.
- the at least one force sensor and optionally additionally the at least one torque sensor can be arranged on at least one interface of the industrial robot provided for this purpose, for example on at least one flange of the robot arm.
- the robot arrangement comprises an evaluation device.

- the robot arrangement comprises a control device.
- the control device preferably controls at least one compensating movement of the industrial robot, in particular the robot arm, as a function of the evaluated position deviation. Due to the controlled compensating movement, the tool holder can be guided so that the assembly means is guided back into the ideal assembly position and / or returns to the ideal assembly position.
- the robot arrangement is thus an implemented control system which permanently ensures the ideal mounting position of the mounting means in the tool holder.
- the assembly connection in particular the screw connection, is of high quality.
- costly interruptions during and / or during assembly due to incorrect positions of the assembly means in the tool holder can be avoided in an advantageous manner.
- the tool holder transfers a force introduced by the industrial robot, in particular a contact pressure, to the assembly means during and / or during assembly.
- the assembly means is acted upon by the force introduced, so that it can be introduced into the bore.
- the assembly means in particular exerts a counterforce on the tool holder when it is received in it. It is particularly preferred that the force introduced and the counterforce are balanced when the mounting means is arranged in the ideal mounting position. In particular, the force applied and the counterforce cancel each other out in the ideal mounting position.
- the differential force can optionally be generated and / or generated by a lateral displacement of the assembly means from the ideal assembly position.
- the mounting means is clamped in the tool holder, so that the differential force is thereby generated and can be detected by the at least one force sensor.

- the tool holder can track the assembly means, so that the assembly means again occupies the ideal assembly position.
- the differential force can be generated and / or generated by a forward displacement of the mounting means from the ideal mounting position.
- forward displacement the assembly means is partially moved out of the tool holder so that it is no longer in the defined recording depth is arranged. In particular, this reduces the counterforce transmitted from the mounting means to the tool holder, so that the differential force can be detected, for example, as a negative differential force.
- the evaluation device evaluates the differential force as a position deviation, in particular as a location and / or direction vector.
- the control device controls the industrial robot on the basis of the position deviation to carry out a linear forward movement as a compensating movement, which is based in particular on the location and / or direction vector, in order to track the tool holder with the assembly means.
- the differential force can be generated and / or generated by a rearward displacement of the assembly means from the ideal assembly position.
- the mounting means is pressed further into the tool holder, in particular beyond the defined holder depth, so that an increased counterforce is generated and / or acts on the tool holder, which can be detected as the differential force, in particular positive differential force.
- the evaluation device evaluates the differential force as a position deviation, in particular as a location and / or direction vector.
- the control device then preferably controls the industrial robot on the basis of the position deviation to carry out a linear backward movement as a compensating movement, which is based in particular on the location and / or direction vector, so that the tool holder can track the assembly means.
- it is advantageously achieved that the assembly means is guided back into the ideal assembly position and / or again assumes the ideal assembly position.
- the lateral, forward and / or rearward displacement / s of the assembly means result from oscillations and / or vibrations of the conveyor belt and / or the workpiece.
- the oscillations and / or vibrations can be caused by irregularities in the conveyance of the workpiece and / or by vibrations in an environment of the conveyor belt.
- the oscillations and / or vibrations can also be generated by any additional work on the conveyor belt and / or on the workpiece.
- the industrial robot is designed to collaborate with the conveyor belt, the workpiece and / or the assembly means Industrial robot trained.
- the industrial robot preferably reacts by means of the control by the control device to the forces which are transmitted to and / or act on the industrial robot via the conveyor belt, the workpiece and / or the assembly means. It is advantageous that, due to the collaboration of the industrial robot with the conveyor belt, the workpiece and / or the assembly means, there is no need for a worker for manual operation of the industrial robot. As a result, the assembly operation can advantageously be completely automated, which in particular saves costs for the use of the worker.
- the robot arrangement for detecting the lateral, forward and / or rearward displacement of the assembly means exclusively comprises and / or uses the at least one force sensor. It can optionally be additionally provided that a deviation between the target torque and the detected torque can be evaluated by means of the torque sensor and the evaluation device and corrected by means of the control device.
- additional sensors in particular optically operating sensors, are completely dispensed with. This can save costs for the additional sensors, for additional programming and / or control technology.
- Another object of the invention is a method for performing an assembly operation on a workpiece with the robot arrangement according to the previous description and / or according to claims 1 to 11.
- the tool holder is attached to the industrial robot and the assembly means is arranged and / or received in an ideal assembly position in the tool holder.
- the industrial robot preferably detects the tool holder independently and places it independently on the robot arm. Alternatively or optionally additionally, the industrial robot independently detects the assembly means and takes it into the ideal assembly position.
- the at least one force sensor detects the differential force that acts on and / or acts on the tool unit during assembly.
- the evaluation device evaluates the differential force as a position deviation of the Assembly means from the ideal assembly position.
