Christopher - AM - 30 Mins - Dewey

After looking at the design of Dewey and the circumstances of the field, I decided to replace the omni wheels and the rear wheel. Then I plan to add three wheels wrapped with tank tread. The reason why is that since there is going to be carpet, the omni wheels may get caught on the carpet. The tank treads should be able to solve this problem. Furthermore, I removed the rear wheel since I don't think it would be necessary. The originally intention of it from the previous team was to provide more stability. But since there's going to be carpet it would slow down the overall speed of Dewey.
