The system described above has been implemented on our
multiprocessor and works well in practice. The first thing we

success rate. A trial was considered successful if the robot

and displaced slightly from the hand's normal line of travel.
Specifically, we tested left and right offsets of 0.5" and 1.5".
The robot's actions were similar for both values, even
