Hahaha soooo good. Nice one James!
The new and improved elastic band turret! I attached a gear thing (Comes with HD servos) to the servo that controls the shooting to allow loading of up to 3 elastics at once! I also attached the turret to the new Galapagos bot for a mobile base! It is also now sturdier with a shorter barrel
Thanks @thetechguru for the code suggestion to move the turret
