Controls: The turret is controlled using an Arduino Mega for the movement, and a Raspberry pi 3+ for the talking and watching. Each gun holds around 18 darts and can shoot 2 darts per seconds. The theoretical speed of each dart is over 100km/h, though in reality it is probably a bit lower. The flywheels are made of quadcopter outrunner motors, and spin at 25000 rpm. 4 Nerf guns: The turret contains 4 fully functional nerf guns that use flywheels to launch the darts. All movements use either hobby servo’s or DC motors with potmeters for feedback. It can move around 20 degrees in all directions, both with the guns and the laser. Movement: The turret can open and close automatically. All of the mechanisms that move are 3D printed. 
All the smooth white parts are 3D printed. Over 300 hours of 3D printing: The turret is an absolutely massive print, containing hundreds of parts.To follow that route from idea to turret, visit the making of part 1 and part 2.
It was later revisited for CCC camp 2019 and finished properly. By then, it was capable of doing everything it can do now, just worse. The turret was originally made for SHA2017 as a show piece. Best of all, it has 4 fully functional nerf guns that together can shoot up to 400 rounds per minute.
It has a laser which can be aimed, and a light up eye. This is a scale 1:1 turret from the game Portal with all things a turret should be able to do.
