I like wheele-wheel that comes out the back when the arm is raised. That will help keep it stable. Very ingenious.
There were some other interesting bots in that video. What is the number of the team with the "C" shaped roller grabber? That robot looks almost
exactly like ours. I would be interested to see how well it did.
There was also a robot that looked like it was 4" tall
That's about the shortest robot I have ever seen!
Any other videos of the scrimmage would be much appreciated.
