We used the same wheels, and after looking at your site it looks like we had an identical layout. One difference though, ours was very easy to control. When we prototyped it the drive wouldn't go in a straight line to save itself, problem with 3 points defining a plane, and four being over constrained. Which is to say every time it hit a bump it would steer into a new direction. By adding a rotational accelerometer and suspension to the platform we got it under control (little joke there) and now it is fun to drive.
