Created by David Wegmuller, this nifty device is basically “a track mounted LEGO vehicle that moves by shifting its own track.” Video demonstration after the jump.

It would place a section on track in front of itself, roll onto it, then pick up the section behind itself. A stack of tracks can be stored and sequenced, in a sense it would be a low tech programmable robot, able to be sequenced to do a predefined looping route. If it sounds familiar, it is because the inspiration came from Wallace and Gromit’s train sequence
