A fuzzy control system for multiple-cooperating tentacle robots

A fuzzy controller is proposed to solve the local control for a multi-chain robotic system formed by tentacle manipulators grasping a common object with hard point contacts. The two-level hierarchical control is adopted. The upper level coordinator gathers all the necessary information to resolve the force distribution. Then, the lower-level local control problem is treated as a open chain redundant manipulator control problem. A closed loop control based on the inverse dynamic model and the direct sliding mode control procedure are proposed. The fuzzy rules are established. Simulation results are presented and discussed.
