Abstract (en)

[origin: WO2021165105A1] The invention relates to a method for controlling a robot manipulator (1), having the steps of: - providing (S1) a database containing body zones of a person, wherein each of the body zones is assigned a particular maximum permissible value of contact pressure, - determining (S2) a current or future contact event involving the robot manipulator (1) and the person and determining the body zone of the person with which contact is made, - determining (S3) a reference position that is fixed with respect to the body relative to the person, wherein the reference position indicates the beginning of the local progression of the pushing-in of tissue of the person during the contact event with the person, and - controlling (S4) the robot manipulator (1) in an impedance-controlled manner in such a way that the determined reference position as a zero position of an artificial spring component is used for impedance control of the robot manipulator (1) and the maximum permissible contact pressure as a limit value is not exceeded.
