The disclosure relates to a method for operating a robot as well as to a correspondingly operated robotic system. As part of the method, it is determined, if a difference between a current position of the robot and a target position of the robot exceeds a predetermined threshold value while the robot is in a torque-regulated operating mode. If the difference exceeds the threshold value, a predicted model-based intermediate state that the robot reaches before the target position according to the model is determined, wherein a speed of the robot in the intermediate state is lower than a predetermined speed threshold. When the robot reaches the intermediate state, the robot is automatically switched from the torque-regulated operating mode to a position-regulated operating mode. The robot then moves into the target position in the position-regulated operating mode.

Work machines, control systems for work machines, and methods of operating work machines are disclosed herein. A work machine includes a frame structure, a work implement, and a control system. The work implement is coupled to the frame structure and includes at least one ground engagement tool that is configured for movement in response to interaction with an underlying surface in use of the use work machine. The control system is coupled to the frame structure and includes a sensor mounted to the at least one ground engagement tool and a controller communicatively coupled to the sensor.

The invention relates to a method for the automated grinding of surfaces and to a corresponding device. According to one exemplary embodiment, the method comprises the robot-assisted positioning of a grinding machine with a grinding tool, so that the grinding tool contacts the surface when the grinding machine is operated at a first rotational speed, and the detection of the contact between the grinding tool and the surface. The method further comprises, as a result of detecting the contact, the increase in the rotational speed of the grinding tool from the first rotational speed to a second rotational speed.

Provided are an operation control device and program that can improve processing speed while suppressing the occurrence of synchronization errors. This operation control device uses a synthesis drive signal obtained by synthesizing two drive signals to drive by switching a drive speed of a first drive shaft, and uses one of the synthesized drive signals to drive a second drive shaft for performing a task different from the first drive shaft. The operation control device comprises: a positional deviation calculation unit for calculating a positional deviation of the first drive shaft before switching the driving speed of the first drive shaft and calculating a positional deviation of the second drive shaft; and a gain value calculation unit for calculating a gain value of the first drive shaft after switching the operating speed, on the basis of the drive speed of the first drive shaft before switching the operating speed, the calculated positional deviation of the first drive shaft, and the calculated positional deviation of the second drive shaft.

A control apparatus for a welding tool includes a determination module for determining a normalized displacement signal, in which a deflection of a tong-shaped tool, due to an effect of a mechanical force generated on the tool during a work process using the tong-shaped tool, is compensated for. The control apparatus further includes a force regulation module for regulating a progression of the force which the tong-shaped tool applies to at least one component during the work process on at least one component. The force regulation module is configured to regulate the progression of the force during the work process based on the normalized displacement signal.

A robot includes an arm that has a plurality of arm members, a drive unit driving the plurality of arm members, and a grasp unit; and a force detector. The robot sequentially performs a contact operation in which a fitting member grasped by the grasp unit is moved in a predetermined contact direction and is brought into contact with a to-be-fitted member, a posture change operation in which a posture of the fitting member is changed to a fitting posture, and a fitting operation in which the fitting member in the fitting posture is moved in a searching direction and the fitting member is fitted into the to-be-fitted member in a fitting direction. The contact direction, the searching direction, and the fitting direction are directions different from one another.
