We made a prototype using nothing more than one of the 3 inch cooling fans provided in the kit, tape and paper (crude I know) and we were able to effectively control the ball. It would roll in any direction you moved the rig providing you didn't move it too fast. Granted a robot would never move so slowly while in possession of the ball, but the rig showed promise. We figured if we could find a fan that rotated at a much higher velocity, therefore sucking more air, the idea could be worth looking more into. However you would not be able to travel over the humps at all. Limiting the robots to the tunnel bottlenecks. I can't say that this is the plan we are going to use, but it would be awesome to see this idea used effectively at a regional! I just had fun rolling the ball with air.
