Abstract: The invention relates to a surgical robot system comprising a robot arm (8) installed on a substructure (1), a first control instance (16) for producing control commands for the robot arm (8) on the basis of user inputs, and a second control instance (18), which receives the control commands from the first control instance (16) and checks the control commands with respect to whether the execution of the control commands by the robot arm (8) requires the robot arm to leave a specified occupied space (21, 22) of the robot arm (8) and releases a control command for execution by the robot arm (8) at most to the extent to which the control command can be executed without the robot arm leaving the specified occupied space (21, 22, 30).

Abstract: The invention relates to a method for controlling a robot system (1) for minimally invasive surgery, which comprises at least two robots (2, 3). According to the invention a port (7), which serves to provide access into the body of a patient (5), is operated by means of a first robot (2), and a surgical instrument (10), which is designed to be introduced into the body of the patient (5) through the port (7), is operated by means of a second robot (3). The separate operation of the port (7) and the surgical instrument (10) makes it possible to guide the port (7) synchronously to a movement of the surgical instrument (10), to damp the movement of the surgical instrument (10) or to block the movement by fixing the port (7).

Abstract: A drive unit (8) for driving a tool. The drive unit (8) has at least one first drive module (18) comprising a motor (12) and a wheel (32) driven in a rotary manner around an axis (16) by the drive module (18). The drive module (18) comprises a magnetic ring (22) surrounding the wheel (32), with which the wheel (32) is connected in a magnetically force-transmitting manner and with which the motor (12) is connected in a mechanically force-transmitting manner.

Abstract: A robot system comprises a base (2), a robot arm (1) connected to the base, a camera (10), at least one objective lens in the camera (10) being movable with the robot arm (1), and a screen (16). A control unit (15) is configured to detect a change in the distance between an object (21) detected by the camera (10) and the objective lens, and to vary the zoom factor of a zoom function of the camera (10) according to the change in distance.

Abstract: The invention relates to a device (2, 6) for manually controlling a robot system, comprising an input device (2), which can be operated by means of at least two hands and has a sensor system (7, 10) for detecting control specifications of a first hand (12) and control specifications of a second hand (13). According to the invention, the control device (2, 6) comprises a first control unit (19), which performs a position control function in dependence on the control specifications of the first hand (12), and a second control unit (20), which performs a velocity control function or a position control function in dependence on the control specifications of the second hand (13).

Abstract: In a method and a restraint system for the controlled paying-out of a seatbelt (16) of a seatbelt system (1) for a vehicle (100) in the event of a crash, a vehicle occupant who is secured by the seatbelt system (1) is additionally restrained by an airbag (110), wherein the paying-out of the seat belt is controlled in such a way that the vehicle occupant (102) is braked, in particular over a predefined time period (txid) in accordance with a characteristic curve (13) to be predefined, the braking operation being such that the vehicle occupant (102) impacts against an airbag which is unfolded in an ideal fashion at the end of this time period.

Abstract: A method for determining a performance parameter of a brake with a first (311) and a second (313) brake element can be made to interact to generate a friction force (FR) and a friction torque (NR), a first set (204a, 204b) of friction coefficients (?) being determined between the first (311) and the second (313) brake element in the field, the first set (204a, 204b) of friction coefficients (?) being compared with a predetermined second set (204) of friction coefficients (?), and the performance parameter being determined based on a deviation of the first (204a, 204b) and second set (204), the deviation being obtained from the comparison.
