Simple Obstacle Avoidance Algorithm for Rehabilitation Robots [PDF]
, 2007 The efficiency of a rehabilitation robot is improved by offering record-and-replay to operate the robot. While automatically moving to a stored target (replay) collisions of the robot with obstacles in its work space must be avoided.
