Re: 6WD Chassis Stiffness vs. Maneuverability

254's 2008 Robot had an extremely low center of gravity. Also, the vast majority of our weight was in the rear of the robot mainly due to the following things:
  • All elevator mounting points were within 6" of rear wheel axle
  • Battery positioned slightly to the rear of center axle
  • Compressor (and most pneumatics) were on rear of robot
  • Due to open front of frame, all electronics (except for speed controllers) were mounted rear of the center axle
I believe that our center wheels were dropped 3/16", and all wheels are 4" diameter and 1" wide, using black roughtop tread

Due to the weight distribution on our robot, the robot rarely had any weight whatsoever on the front wheels. When changing tread throughout the season, the front wheels rarely required a change (they probably could've gone the whole season on one set of tread). However, the center and rear wheels burned through tread much quicker (during competition, we typically changed the tread about once per day of competition, but always had a spare set of treaded wheels ready)

During play, the robot was probably on the rear/center wheels over 90% of the time, and only really rocked during quick stops and reversals of direction.
