When we were in skid steer mode we had a wide aspect ratio. Traction was a consideration. As the tires wore down and got stickier it was harder to turn. In the off season we put tape on the front tires to reduce traction to make turning easier.
In the past we had long aspect ration bots with skid steer. In 2004,5 our tires were about 10-12" OD. They took lots of power to turn and were not " precise". On a high center of gravity machine there was quite a bit of bucking/tipping. We started out this way in 2006 and ended up with 2 omni wheels before we shipped.
On a low CG bot the long aspect ratio configuration was OK. In the future we'd most likely go with the 6 or 8 wheel design.
