Building robots out of liquid may streamline manufacturing

Build this Raspberry Pi guardian robot and stave off intrusions! A new DIY build, courtesy of the good folks at Dexter Industries. MIT's Computer Science and Artificial Intelligence Lab (CSAIL) is 3D printing robots. The idea is that one of the biggest barriers to long-promised robotic revolution is in manufacturing. Robots have a lot of parts, and manufacturing them is expensive and highly specialized.
