Our Innovations: Our design to detect weighted rings won us the innovate award. A Lego piece connected to a zip tie is placed on the bottom of the claw, which works like a seesaw: if a weighted ring is picked up, the Lego piece tilts, and the zip tie goes up.
The Hidden part of our Robot: For our elevator lift to work effectively it requires two motors on each side, lifting the linear slides. Placing these motors was a challenge so we spread out the motors back across the robot. Putting two gears on an axle and then attaching motors to them gives the same result as putting two motors around a single gear.
