I made ours out of 1/8 6061-t6 with a small bend radius. Upon a few minutes of test driving we had a lot of bent yokes which lead to rollers hitting each other and the hub. We ended up with 11 gauge, (~.110) steel which worked like a charm, we also put a huge radius in the corners.

Hope it help.

We have actually driven the robot many times and we have not had any problems. We had a test chassis before this one and we drove it for at least 2-3 hrs total with no problems at all. We were driving it really hard to. Thanks for the concern though.



And we made the rollers from polyurithain(I just butchered that word!!!)
