I like the hexagon shape. I'm assuming its to "help" get out of T-bone situations, if necessary?

True more space could be had, though not as much as you think. We did the stand off to bumpers on last years WCD 6 wheel robot.. Was very robust.

But we still didn't like the bumpers. We used 2 "C" shaped bumpers and was strong but was not to our liking. The idea is to have a one piece bumper drop over and lock on.
Yes this hex frame was done with "Tbone" in mind. Though last year with the 6 cim 2 speed low gear layout we had not many issues with that. Though it should help with getting pinched against a wall..
This is an off season project to try out some odd ideas thought up. The transmissions were done separately so that they can be used in other areas beside just drive.
We like the idea of putting the motor weight over the main drive wheels with the battery centered. Even though this looks like less space it has more internal space than last years robot. The outer frame is 2x1 while the drive tubes are 1.5x3". Gives a great exterior edge for LED ground effects.. FRC Swag!
We were so underweight last year.. Was strange to have to add weight, so we were not concerned with that on this prototype.
The idea is to have the electronics tray nested with the pneumatic shifters and run a plate above all of that level with the top of the frame for a clean deck almost the entire size of the robot. We will have the battery and electronics orientated flat at that time. The vertical battery was added to check the COG. which at the moment is centered on the robot at 4" off the ground.
Not knowing the game this platform leaves a lot to play with.
Of course as soon as the game is released all will change.
If desired I can put up some other views of the drive. There are some newer revisions done and can put up some of those pictures if desired.
Thanks for the comments, keep them coming.
