Ohh, the horrors!!!!
Designing a gearbox is a pain. We had the hardest time designing a gearbox that would actually work. Tristan Lall helped quite a bit but we had to make modifications because we decided to use 24" bike wheels. We found that to avoid having two stages of sprockets we had to make very significant modifications. So we did design it and we got it machined but we had lots of trouble with it at the competition. First of all, they turned out to be really heavy with all the 72 tooth gears we had in there. Secondly we had problems with the press-fit bearings falling out. Balancing weight, speed and torque for the very first time was a very big challenge for our two 17-year-old mobility people.
EDIT: We had planned to go up the 6" side of the platform and we had calculated the torque required to do that given the estimated weight distribution of the robot. So we needed more than around 110 Newton metres of torque after taking into account 70% efficiency per gearbox.
