Frame information

Drive base dimensions: 25" wide x 37" long.
Front is straight across
Rear is 16" straight
Both ends are chamfered 4.5" width x 5" length
6 wheel design with pneumatic tires, wheel spacing is 9.5" between wheels
Wheel axles are 9 inches from each end
Center wheel dropped 1/4 inch
Frame construction is "c-channel" and 1.125 wide x 1.250 tall and will be a welded construction
We tested a frame mock up over all the defenses. The comment is the Frise will require a belly pan
The moat will require a chamfer on the bottom edge of the rear and front members

Transmission

Cim-ple box from andy mark 12 x 56 tooth (4,.167 reduction)
The secondary reduction will be 12 x 36 tooth for a 14:1 overall reduction
the wheel speed is 10.29 ft/s loaded
(We are considering mounting the drive chains on the outboard side of the wheel channel to create more space in the center of the robot)
