It looks like a good clean kitbot, with some great bumpers. I didn't check to see if you welded the frame, but if you run into weight issues welding not only adds stiffness but loses a pound or so of nuts and bolts. Some teams also use big rivets to hold the frame together.

Do lots of testing with the chain... forwards, backwards, forwards, backwards... into a wall slowly, into a wall quickly... preferably with some weights attached to approximate your final weight.

While various mechanisms can fail causing your robot to be less effective in a match than hoped for, when you lose a chain you become ineffective. Been there, done that, it is no fun at all.

I'm not saying that this set up won't work reliably, but if you lose a chain during the build period... even once... do not shrug it off as a fluke. Your robot is telling you something.

P.S. Have you tried pushing the ball against a wall yet? I'll bet it just jumps right up on top of your chassis, right where you want it.

P.P.S. If you have a couple Victor Speed Controllers left over (or if you order two more) you can order two extra CIM motors for $24 each and double your torque.... or change your sprockets and increase your speed.... unless you are already planning to use the extra CIMs elsewhere. If you do that, though... retest that chain set up at the higher torque settings.
