<Li> A cylindrical, rotating trunk section with extending bellows arms that terminated in red mechanical claws . The trunk section had controls, indicators, a small sliding translucent door through which data tapes, similar to punched tape, could be accessed ("The Hungry Sea"), a removable power pack and a signature chest light that illuminated in synchrony with the Robot's speech (May had a key inside the suit that he would tap in time with his speech to illuminate the light, resulting in some scenes where one of the claws can be seen moving in time with the light); </Li> <Li> Bellows legs that were understood to move with some agility but which, due to real - world practical limitations, were rarely seen on camera to move separately; and </Li> <Li> Trapezoidal continuous track units at the bottom of each leg . These normally paired as a single locomotive device, but they also could function as individual feet . The leg and tractor sections apparently could be readily detached, allowing the Robot to be positioned in the rear of the Chariot ATV, although the actual disconnect operation was depicted only once . </Li> <P> According to the series </P>
