  • Robot arm and method of controlling robot arm to avoid collisions
    Patent number: 8340820
    Abstract: A method of automatically controlling an extendable robot arm to avoid collisions while returning to a first position from a second position includes periodically storing locations of the robot arm as the robot arm moves along a forward path from the first position to the second position; applying heuristic algorithms to the stored locations to determine a return path to the first position, the return path including at least a portion of a retrace path retracing the stored locations of the forward path; and controlling the robot arm to return to the first position using the determined return path.
    Type: Grant
