Design and Implementation of Non-prehensile Manipulation Strategies

Grasping of objects is not always feasible for robot manipulators, e.g., due to their geometric properties. Non-prehensile manipulation strategies can enable manipulators to successfully move these objects around. We discuss strategies for non-prehensile manipulation and focus on the investigation of such manipulation strategies based on open-and closed-loop control based on force torque measurements. The design of grippers for moving objects is also an important factor that is evaluated. The strategies are implemented and evaluated in simulation and on a KUKA LWR4+ manipulator arm.
