Re: Our Team Needs Help on the Drive!

It's interesting to see some convergence. These are the drive configurations for our two leading design concepts.

Code:
 One Wheel           Two Wheel
      _                  _     

|    //    |       ||         ||

      _                  _
      O                  O

// = driven and steerable,  || driven fixed,  | and _  fixed freewheeling.
O = Trailer Hinge Pin

Design CG is over the single driven wheel for one wheel drive
and between the  two driven wheels for the 2 wheel drive. 
Driven wheels are dropped so that the non-driven wheels 
do not normally touch the ground unless external forces are in play.
