The wheels we purchased are probably going to be too small, and difficult to attach a sprocket to. I saw this option which would really simplify the drive train construction. By combining a sprocket and wheel, it removes one challenging bit of construction. I wish I had my own lathe! Still, $200 for wheels is a little more than I wanted to spend. I also wanted to see if I could run with a live axle (where the axle is mounted on bearings and the wheel and sprocket get mounted directly to the shaft). For example, using a sprocket like this and a flange bearing like this, the robot could run a live axle.
I'm itching to order something new... drive train... electronics... hmm.
