Cyborg arm made of Lego can flex its fingers and shake hands
It certainly isn't the first robotic arm made out of Lego that we've seen, but this particular one can actually be worn and easily controlled by the user.
According to its creator, Diavo Voltaggio, the arm was made using Lego Mindstorms EV3, which is a software-and-hardware kit for DIY robots. He says the machine is pretty straightforward: it has four buttons connected to four motors that control each finger.
