We built our practice bot first out of steel parts, because one of our mentors could get those for us as soon as the cad was finished. We then built our main bot our of higher tolerance aluminium parts. We though that we were going to have to keep the steel bot as our practice bot because it would be to heavy (it wasn't), but we wanted to have more add on room so we used the aluminium bot for competition.
