Autonomous Caterpillar

Autonomous Caterpillar made with Lego Technic that is operated by an XL motor. The reciprocal movement is performed by a switch and the segments are contracting my means of a winch/rope with springs as counterforces.If you like my models, I would appreciate it if you would endorse my Rolls-Royce Phantom II on Lego IdeasBe sure to also check out my other models on Rebrickable.
