I have been running into this issue and I am not sure how to solve it. I am also looking to make a tracked bot but I don't want to have to machine all the "track roller things" my self, Does anyone have a good idea on mounting these plastic "track roller things" ( http://www.hobbyengineering.com/H2028.html) to bearings then bearings to the base?

my guess would be pillow block bearings, but that depends on size

I actually thought about that but the cost of the pillow block set would be greater then the robot itself.
I could machine my own but I don't have CNC set up on my mill and it would be a pain to do it by hand.
Off Topic: anyone know of a good 4 axis stepper motor driver for under 100$USD?

Instead of using all the track rollers, just use one on each end and place a smooth piece of plastic along the surface that the track is running.

Thats actually a great idea I could even machine the grooves for it so it wouldn't get out of place - it still leaves the problem of mounting the two end rollers to bearings though, I don't have any aluminum ATM - I only have a bunch of cutting boards, Anyone have an idea on how to machine and setup a pillow block configuration for each side on one end? I got a couple of rough ideas but nothing to point of actually being able to create it.
Thanks everyone for all the help and ideas -
