prototype mechanisms for autonomous dealies that can scale the straightest of walls, but never have we seen so many gathered together into what can only be called a festival of disconcerting feats of robotic ingenuity. One uses magnets, one has little claws, and one uses integrated hot glue guns that would leave you with no doubt that something sticky had been exploring your walls. They were all developed by a team of engineers working with Amir Shapiro at Ben-Gurion University in Israel, where he studies biomimetrics: technology that tries to do what animals do. Applications for all this? The Israeli military is apparently quite interested, a force that we will be working extra hard to stay within the good graces of from now on.
