Abstract :
This paper presents the near time-optimal motion planning method for moving obstacle avoidance. We decomposed the robot motion into three phases: approach, contact, and detachment phase. The constraints of each phase for a feasible collision-free robot motion were described by three necessary and sufficient conditions and one sufficient condition. We formulated the near time-optimal motion planning as optimization problem with inequality constraints. Simulations present the efficiency of the results by comparing them with two widely used approaches: reactive and path-velocity decomposed approach.
