We are thinking about doing a very similar thing with a wide chassis. I don't see the need to have power driven to the front two wheels because that just takes up extra weight and you don't have to push against other robots this year, just the totes. If you have time why not test both ideas? You could have a small piece of plywood angled at 16 degrees if you didn't build the scoring platform and push a tote that weighed 50 pounds up the ramp. If you are happy with how it preforms then you have found your solution.

On a personal note chain can be a pain some times to get just right and add a lot of weight and precision machining to the chassis. Just remember to always keep it simple! Our design over all at the moment uses 2 CIM motors, a compressor and 2 pneumatic pistons. We might bump it up to 4 CIMs but we aren't sure yet.
