Re: designing a better kit frame.
while this may not be massed produced, after our 2012 season, i will probably write a full paper, cad a sheet metal version, and submit it to Andy-Mark. you are correct that this frame has a TON of CnC work. however, the frame and gussets themselves only weigh 8.3 lbs, which of the amount of strength this frame would have, extremely light. the other advantage, is that even if we are unable to pre-fabricate the pieces, they can be fabricated durring the finalization of the design, and the CAD. which will still cut a 4-6 days off our build season.

while the 3*1.5 tube in this version dissalows more than 4, 6 at maximum different axle positions, the previous version used 4*2 tubing, and each wheel had 12 different positions. the 3*1.5 tube saves 4-5 lbs over the robot, but does make it a tiny bit less flexible. a sheet metal version could probably accommodate a larger number of axle positions.
