Navigation and control of autonomous mobile vehicles with onboard manipulator systems are currently being investigated for intelligent manufacturing applications. A systematic approach for modeling and base motion control of a mobile vehicle with an onboard robot arm is presented. Feedback linearization is used to take into account the complete dynamics with non-holonomic constraints, yet methods from potential field theory are incorporated to provide resolution among possibly conflicting performance goals (e.g. path following and obstacle avoidance). The feedback linearization provides an inner loop that accounts for possible motion of the onboard arm. The two cases of maintaining a desired course and speed, and following a desired Cartesian trajectory are considered. The outer control loop is designed using potential field theory, with the two objectives of homing and avoiding an obstacle. This simple result obtained using potential functions provides very naturally the necessary intelligence for online resolution of conflicting performance objectives. It gives capabilities to these autonomous vehicles for maintaining a desired course and speed or tracking a Cartesian trajectory, avoiding obstacles during the course of travel, and initiating new online path planning when the size of the object is large so that unnecessary wandering in the work space is avoided.
