Last year, the bobcats had two robots.... we built spare parts when we were building hte actual robot. I.E. if we were building hte motor mount, we machined 2 or 3 instead of just one. As for the electronics, we did quite a bit of stealing off of other machines, and we may have ordered a few more things from IFI.
our 80/20 (
www.8020.net) frame also made this a lot easier, we were able to assemble our entire frame in a little under 2 hours.
