Not really boundary-pushing or anything, but perhaps interesting:
- 80/20 and C-channel get a bad rep for being really heavy, but our robot is made almost exclusively of them and is about 87 lbs this year
- We have duct tape, wood, zip ties, and sliced pool noodle (not in bumpers) in important, visible, and structural applications. Finalist at TC district, and qualified for CMP!

- These stars from Andymark; is anyone else using them? Great for the intake.
If we want to include some of the past, a plastic broom handle became part of our 2010? robot.
EDIT: The post after about the wrench reminded me that we needed a spacer at Escanaba to help our shooter: we used a sharpie. It was replaced by the wood mentioned above for TC.
