I-Wei thought his SwashBot 2 was cool and all, but had lost some of the character of his original SwashBot. So, he built a third version that combines the mobility of the second with the charm and personality of his first crab bot. To build the body and the leg components, he used an amazing molding material called ShapeLock. Seeing the results definitely makes this something I want to check out. You can mold it very thin and flexible for the body pieces or thick and rigid for functional components like the leg segments.
