The sixth film shows a robot arm using touch/force feedback that is able to do some sophisticated tasks: (1) pick up a block after the experimenter has moved it to a new location, (2) align a block it is holding with one the robot wants to put it on by tapping the target supporting block to find its position, (3) stack blocks on top of a narrow base without knocking them over, (4) grasp blocks held in the experimenter's hand, (5) insert a tight-fitting cylinder into a round hole by tilting and sliding it, using force feedback, and (6) turning a crank handle.
