The phrase “autonomous cutting machine” may sound like something out of Terminator but this clever little robot, called the Goliath CNC, wants to help humanity, not harm it.

Created by Lorenzo Frangi, Alessandro Trifoni, and Davide Cevoli, the robot is basically a free-rolling CNC machine that can crawl over a surface and etch and cut lines into many materials. The machine uses a drill bit and multi-directional wheels and can automatically measure the size of the material you’re cutting.
