ABSTRACT:
In a system for obstacle avoidance path finding for a multiple-degree-of-freedom mechanism such as a mobile robot moving from a starting point to a goal while avoiding obstacles. Obstacles are defined to be a virtual space having a continuous drag coefficient that increases with increasing proximity to the obstacles. A path is determined on the basis of the variational principle as the extreme for a functional such as time required for the mobile robot's movement. Since the viscous drag coefficient is greatest at the obstacles, the determined path does not go through the obstacles thereby avoiding the obstacles. Moreover, since the path is determined on the variational principle, the time required for the movement is adopted as the functional, the determined path will locally be that of minimum time.
