Title: Planning and Control of Multi-Contact Interactions with Humanoid Robots: Grasping and Balancing

Abstract:
Balancing and grasping are two different activities of humanoid robots, which share the same mathematical framework. This can be exploited both in planning and control level. At planning level, different approaches for creating goal poses for both activities will be shown. Passivity-based impedance controllers, based on joint torque sensing, have been traditionally applied to manipulation tasks. Experiments on grasp and reach-to-grasp will be presented in this talk, showing how the controller can cope with positional uncertainties of the object. The same framework is applied to obtain a whole-body posture controller in the robot TORO, a humanoid robot developed at DLR based on the technology of the KUKA-DLR LBR (Lightweight robot arm). This posture controller is extended for a multi-contact scenario, thus obtaining robust balancing behaviors even with uncertainty in the supporting surface.
