I can't say I quite follow this explaination. I would think casters would be ok in any situation as long as the center of mass was near the drive wheels. But if it wasn't, I'd think that this year, having casters at the back of the robot would be preferable. Mainly because it's hard to push a shopping cart uphill without it turning to the side.
Thogh now the I stop to think about this, I think the actual key is to have you center of mass behind your center of rotation. At least when you're going uphill. Alright, I know you center of mass is actually where your robot rotates, I'm talking about where it would rotate if mass wasn't accounted for (ie. the point between the wheels in a 2WD). Of course it's too early for me to really think about the physics of this. All I know is that I saw way too many rear wheel drve bots running into the sides of the ramp at Lone Star.
