A METHOD AND AN APPARATUS FOR AUTOMATICALLY GENERATING A COLLISION FREE RETURN PROGRAM FOR RETURNING A ROBOT FROM A STOP POSITION TO A PREDEFINED RESTART POSITION

摘要

The present invention relates to a method and an apparatus for automatically generating a collision free return program for returning a robot from a stop position to a predefined restart position when the robot has been stopped during operation due to an error. The apparatus comprises a receiving part (12) adapted to receive a request for a recovery path and information on the stop position of the robot, a path generating part (14) adapted to generate a collision free recovery path for the robot upon receiving said request, based on the predefined restart position and the stop position of the robot using a path planning algorithm that generates robot positions connected by collision free path segments, and a programming part (16) adapted to generate the return program based on the generated return path.
