Using just two motors, would it be better to chain drive 4 wheels , or direct drive two wheels with two free spinning wheels (casters, 6" skyway, etc.) ?

Our team was originally planning to use 4 CIM motors (they shipped us four) until we read the rule mentioning "using motors in quantities provided" (Update #2)

Really Really need help as we are falling behind!!!

You aren't that behind yet.

If you do power all four wheels there are a few things to consider first. Primarily, how wide is your wheelbase? The longer the wheelbase, the harder it is to turn. This also occurs when each wheel in the skid steer has enough traction that it doesn't want to turn because of all the scrubbing. You may want to look into using omniwheels for one of the wheel sets. Do a search on Chiefdelphi or in any search engine to find different styles. Note: if omni wheels are used, you pivot will move back to the center of the non omni wheel set.
