Everything is polycarbonate except the PVC rollers and the acetyl gear on the turret. We make everything we can out of it. It weighs 112 pounds. We work out of a plastic fabrication shop, so the material is a natural choice. As for the weight compared to aluminum, polycarbonate is less dense than aluminum, but we have to use more of it to maintain structure. We "pocket" the material on a CNC router to reduce weight. That is what the white spots are.

Our electrical team had a tough time fitting everything on the robot, but they did a great job. We also have pneumatics for shifting. It's a little cramped but we made everything fit.
