There’s tech geeks, and then there’s this guy. Meet YouTube user kss5095 and his scratch-built, tracking AND firing Portal turret. Built for his Advanced Mechatronics class at Pennsylvania State University, this particular doppelganger of the murderous (yet cute) robots in the game Portal can track you using an attached IP camera and shoots Nerf bullets at you until you fall dead (or until it runs out of ammunition). The device was made using Arduino and is controlled via MATLAB. While it’s currently naked as of the moment, it’s creator promises it’ll be making an outer shell and will be improving the design to make human-oriented elimination via Nerf guns as swift and as efficient as possible. Check out the full video below.
