Abstract: A manual robot control by which a reference point of the robot is moved continually in space or positioned on an adjacent snap point depending on the control input.

Abstract: An end effector (60) comprises a base (63), a first gripper (64) connected with the base (63) so as to swivel around a gripper axis (68), and a positioning element (66) which is guided on the base displaceably along an end effector axis (76) and interacts with the gripper (64) via a guide slot system. The gripper axis (68) extends outside of a guide slot (70) of the guide slot system.

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 control device (25, 28, 29) for controlling a robot system (11) with at least one robot arm (14, 18) on which a surgical instrument (15, 19) is secured that has an end effector (17, 21), wherein the control device (25, 28, 29) comprises an imaging system (25, 28) that records the control specification of at least one hand (30L, 30R), evaluates it and converts it to corresponding control commands for one or more components of the robot system (11).

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: 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).
