Abstract: The invention relates to a robot (R, 70) and to a method for controlling a robot (R, 70). The distance (d) between an object (P) and the robot (R, 70) and/or the derivative thereof or a first motion of the object (P) is detected by means of a non-contact distance sensor (20, 20?) arranged in or on a robot arm (M) of the robot (R, 70) and/or on or in an end effector (19?) fastened on the robot arm (M). The robot arm (M) is moved based on the first motion detected by means of the distance sensor (20, 20?), a target force or a target torque to be applied by the robot (R) is determined based on the distance (d) detected between the object (P) and the robot (R), and/or a function of the robot (R) or a parameterization of a function of the robot (R) is triggered based on the first motion detected and/or a target distance between the object (P) and the robot (R) and/or the derivative thereof detected by means of the distance sensor (20, 20?).

A medical tool (21 -24) is fixed to a fixing device (18) on the robot (R) and the working range (30) of the robot (R) is set by the controller (17) in particular with safe techniques such that the robot (R) meets the performance requirements of the medical tool (21-24).

Abstract: The invention relates to an X-ray device (2) for a medical workplace (1, 21). The X-ray device (2) comprises a robot (R) with a plurality of axes (9), a control device (10) for controlling the axes (9) for movement of the robot (R), and a fastening device (8), and a support device (11) disposed at the fastening device (8), said support device comprising an X-ray radiation source (12) and an X-ray radiation receiver (14). A 3D model (15, 15a) of the robot (R) and the support device (11) provided is stored in the control device (10), said 3D model modeling the spatial extension of the robot (R) and the support device (11) during movement of the robot (R). The 3D model (15,15a) also models the spatial extension of at least one other device (3, 4, R2) of the medical workplace (1, 21) and/or of a living organism (5) located within the medical workplace (1, 21).

Abstract: A method for error recognition in a control system of a medical treatment and/or diagnosis device includes processing, by the control system, data in a regular operating mode and supplying, by the control system, test data of a test data record to a safety-critical component of the control system in a test mode of the control system. The safety-critical component of the control system is also checked in the test mode of the control system.

Abstract: The invention relates to a medical device, a medical work station, and a method for registering an object (P). The medical device comprises a navigation system (17, 18) and a robot (R) having several axes of rotation (1-6). The navigation system (17, 18) comprises a detection device (18) for detecting prominent points on an object (P) or markers (M) placed on the object (P) as well as a processing device (17) for determining the position of the object (P) on the basis of the prominent points or markers (M) detected by means of the detection device (18). The detection device (18) of the navigation system is mounted on the robot (R).

Abstract: The invention relates to a method for determining a position for and positioning a detection device (E) of a navigation system. First, a computer simulation of a system is done that comprises a robot (R) which has first markers (M1) of a navigation system or first prominent points, a three-dimensional object (P) which has second markers (M2) of the navigation system or second prominent points, and a detection device (E) of the navigation system. Various positions of the robot (R), the object (P), and/or the detection device (E) are simulated, and the quality of the detectability of the first markers (M1) or the first prominent points on the robot (R) and/or the second markers (M2) or the second prominent points on the object (P) are automatically determined for the simulated positions by means of the detection device (E). The determined qualities and the corresponding simulated positions and/or the simulated position having the highest or at least a sufficiently high determined quality is/are output.

Abstract: In a method to test a brake of a robot that has a number of axes, an actuator associated with one of the axes, a brake associated with this axis that is set up to at least reduce a movement of this axis, and a torque sensor associated with this axis, which determines the torque acting on this axis. The brake is activated, the torque acting on the axis is determined by the torque sensor given an activated brake, and the functional capability of the brake is assessed in a processor based on an evaluation of the torque determined by the torque sensor.
