I really like your silo helix. It was an idea that our team brainstormed, but due to our limited resources we had to go with a
more economical way : velcro, and lots of it. I think at one point there was something like 70 linear feet of it used just on the silo. Anyways, your robot is looking really good. Lots of interesting features that undoubtly make you one of the teams to beat. Good luck with your competitions!
