Technic RC Wall-E
WALL-E has six Power Functions (PF) Medium Motors to drive its Technic Treads, move its arms, tilt its head, and rotate its neck. Each of these movements can be independently done using three PF Remote Controls and three PF Infrared Receivers. A small 9V battery is connected to a custom PF wire (shown in a photo), such as this one: http://mechnable.com/content/minizip-shop/
