Walkman, a 12.7-cm (5-in) tall robot, was built from the remains of a Sony Walkman costing  US$1.75 (£1.15) at the Los Alamos National Laboratory, New Mexico, USA, in 1996. In tests the robot struggled to get free when its legs were held without being programmed to do so, and without making the same movement twice.
