Twitchie Scorpion from make magazine on Vimeo.
The robot itself is actually called Twitchie. It’s a DIY robot kit with everything you need to make the final product. The Makers then encased the old boy in a plush body and added a spiky, pointy tail. The final product, which runs around at the end of the above video, is pretty ingenious. Once he gets going this monster looks pretty scary and life-like.
