The basic idea of this construction was a tripod made of three independently controlled linear actuators. It sounds simple, but was quite challenging, since I wanted to be able to control it by moving only one actuator at a time. It was possible only with three actuators, and only with a very specific geometry of the element that connected their tips. The tripod was set on a Hailfire Droid wheel, that served as a base for the rotation mechanism. On the tripod, there was a simple gun with rotated barrel and the fiber optics element powered by a single motor. When I’ve been building this version, I’ve learnt about the firing mechanism developed by the LUGPol user Duku. With his kind permission, I have installed on the tripod a second version of the gun, that looked completely different, but was able to actually fire projectiles.
Despite its simplicity, the gun was able to fire 12 projectiles over a couple of seconds at a range of up to 3 meters. The ammo clip was moved by the gravity, and ejected from the gun when empty. The whole mechanism has later become a subject of my study, with the intent of using it in some military models.
