Hi everyone AREM2326 here with my first EV3 project, the Mad Scientist Mousetrap! It uses only parts from the 31313 EV3 set. I designed this great ball contraption robot for the out of the box building challenge. The purpose of it is to help mad scientists catch mice for their experiments. It consists of five main parts, the bait platform, the pusher, the blender, the saw, and the hand. I will describe all of them in the next steps.
