Re: 6WD Chassis Stiffness vs. Maneuverability
This past year we went with 2WD but in 2007 we had 6WD. I found the robot that year to be very maneuverable and we only had, I believe, a 16th inch drop on the center wheel along with six two inch wide traction wheels. I would be inclined to agree with you that chassis stiffness is a big factor in turning ability because that year we had a welded box aluminum frame that was very stiff. Testing may be the only way to get very good answers. If you have the time to spare try building a few different chassis designs before the build season and test out their turning capabilities.
