Very nice.
reminds me of ours. I personally took a great part in their manufacture. I am very proud. Ours are doubled up but ofset so they run real smooth. But to keep the weight down we had to cut the inard aluminuim down. We overdid it. We were testing the robot without our bumper, hit a the stairs and
bend !!!

They were easy to fix.
Man i love those wheels.
