MIT AI Lab Arms (AI Film #7)

This film shows a fairly conventional robot arm being manipulated by a joystick. Then it moves on to show the "Minsky-Bennett arm" that used to hang in the 9th floor machine room at Tech Square being manipulated by Minsky to reproduce his movement of a joystick. This was a high-speed, high-powered hydraulically driven arm with many joints and degrees of freedom. Minsky shows his faith in the device by having it wrap around a young girl. Later, another person drives the arm, which is at this point shrouded in a tube looking like an elephant's trunk.
