Abstract :
Most research on vision and force control of robot manipulators has assumed that the kinematics and constraint surface are known exactly. In this paper, the vision and force control problem of robots with uncertain kinematics, dynamics and constraint is addressed. An adaptive setpoint control law based on neural networks is proposed. Sufficient conditions for choosing the feedback gains are presented to guarantee the stability. Simulation results are presented to demonstrate the effectiveness of the proposed controller
