Hi-Torque and Good Speed
Team 535 used two drill motors (one per side) with associated transmission. We had one motor driving two wheels using a chain. On the output shaft of the drill motor we attached an 18 tooth gear and at the wheels we had a 60 tooth gear.
During testing we tried 12, 14, 16 and 18 tooth output gears and found the 18 tooth was the best for speed and torque.
We were able to pull the goals or the stretcher with absolutely no problem.
We also had the speed to auto-balance on the bridge with one or two goals securred to our robot.
