A redundant mobile manipulator composed of a three-wheeled non-holonomic mobile platform and a AT-degrees of freedom (DOF) onboard manipulator is investigated in this paper. Redundancy for such a robot is exploited to avoid tipover via online adjusting self-motions. The dynamic model is established and a new tipover criterion is proposed considering inertia, gravity and acceleration. An online fuzzy logic (FL) self-motion planner and a robust adaptive controller are presented to prevent the robot from tipover without affecting the end-effector's motion tasks. Real experiments for a redundant mobile manipulator demonstrate that the proposed algorithm is effective.
