A method of controlling a robot manipulator, the method including: providing a database containing body zones of a person, wherein each of the body zones is assigned a respective maximum permissible value of contact pressure value, determining a current or a future contact event of the robot manipulator involving the person, and determining a body zone of the person that is contacted, determining a reference position fixed relative to a body of the person, wherein the reference position indicates beginning of a spatial progression of depression of tissue of the person during the contact event with the person, and controlling the robot manipulator in an impedance-regulated manner, such that the reference position serves as a zero position of an artificial spring component of impedance regulation of the robot manipulator and a maximum permissible contact pressure is not exceeded as a limit value.
Manipulating fracturable and deformable materials using articulated manipulators
In an embodiment, a method and system use various sensors to determine a shape of a collection of materials (e.g., foodstuffs). A controller can determine a trajectory which achieves the desired end-state, possibly chosen from a set of feasible, collision-free trajectories to execute, and a robot executes that trajectory. The robot, executing that trajectory, scoops, grabs, or otherwise acquires the desired amount of material from the collection of materials at a desired location. The robot then deposits the collected material in the desired receptacle at a specific location and orientation.
