We looked at both 4 wheel tank drive and 8" mecanum drive.
We built a kit base during week one, and mounted the toughboxes and kit wheels to create 4 wheel tank drive. We build a quick base out of wood (with similar dimensional properties as the kit base) and mounted the 8" mecanum wheels and BaneBots gearboxes.
After a few days of testing, we decided that the mecanums were the way to go. It was much easier for the robot to climb the hump, especially when starting at low speeds. Also, we found that we could strafe across the top of the hump, giving us a great way to approach the tower and hang. Plus, they look cooler.
