The system to get fuel into the shooter is composed of an agitator at the bottom of the fuel hopper and an elevator to get fuel from the hopper to the shooter. The agitator is a floor made out of two rollers with polycord belts. The belts feed fuel towards the elevator. The elevator is a similar system to the agitator, with rollers and polycord belts, but it is mounted vertically to feed fuel into the shooter.
Both mechanisms are powered by BAG motors on 10:1 Versaplanetary gearboxes. This gearbox was chosen as it allows us to easily change the ratio if we need to.
