Polymorph Caterpillar Resurrected

This one was on the pipeline for a long time and I've been building it for some time now. It´s my small tribute to Oddbot's Polimorph Caterpillar. Loved the mechanics of it and I'm still struggling with it. Lets see if I can make it walk, as for now it only twitches in the same place. Perhaps it's from the legs, couldn't find anything appropriate to use so I improvised with some bathroom foam :) but it is hard to shape so i t could be holding it back... I don't Know... It uses 8 micro servos, 1 Arduino nano from China :), 1 HC-SR04, 4x1,5V batteries and it will use one 9V for the Arduino (for now it is USB powered) and lots of Polymorph that took forever to shape... :) I hope I'll post another video as soon as I can make it run forward...
