Catapult without a bottom base built from LEGO Mindstorms EV3

Building instructions for the LEGO Mindstorms EV3 Catapult. The robot has a motor, a clutch to control it for manual shooting and a touch sensor for automatic loading. The bottom base is removed which means the Catapult could not be turned around. Nevertheless, the baseless robot is small enough to be built in class.
