We ran a 6wd WCD in the fall to test new ideas for the 2014 season, especially play around with belts. All pulleys had 24 teeth and were made of aluminum pulley stock. We had a tensioning system in place, but rarely had to tension after putting the belts on. It should be made to note that during these tests we added weight to our robot to reach 120 lbs so we could determine a factor of safety for each type of belt. During these weighted tests, we ran full forward, full backward, into walls, and rapid spin turns and reversing spin directions to test the belt reaction. While under lower weight and low risk driving both belts performed equally, however upon testing the heavier robot and heavier driving we found the GT2 belt start to ratchet, while the HTD belt stayed in place.
