Sensitive Manipulation
Link
Abstract:
In this approach, manipulation is mainly guided by tactile feedback as opposed to vision. The traditional approach of a highly precise arm and vision system controlled by a model-based architecture is replaced by one that uses a low mechanical impedance arm with dense tactile sensing and exploration capabilities run by a behavior-based architecture.
The robot OBRERO can come gently in contact, explore, lift, and place the object in a different location. It can also detect slippage and external forces acting on a object while it is held. This tack can be done with very light objects with no fixtures and on slippage surface.
