When is an obstacle a perfect obstacle?
Proceedings of 1995 IEEE International Conference on Robotics and Automation, 1998Owing to the exponential costs of path planning in a continuous or graded cost environment, robot motion planning traditionally makes the "perfect obstacle assumption" and divides workspace into perfect obstacles and perfect freespace, although in practice such a black-and-white distinction is rare. Under the above definition, however, many finite cost
