We like to keep things simple yet maneuverable, so we will be going with a tank-steer 4WD this year. Although four wheels may not have as much contact with the ground as treads, we feel that if we obtain wheels with a high friction coefficient, we can achieve almost as much traction, with less scrub.
We have worked with treads before, and they did not work out well for us. We tried to counter our issues with air rides, however, problems still came up.
At any rate, with the 4WD drive we should be able to have a decent turning radius, which will lead to greater maneuverability, which in turn will allow us to go around the goals and any of the other 5 robots with ease
