My math just assumed that the front bottom edge of the frame formed a right traingle with the ground and the point where the drive wheel makes contact with the ground.

From my experiance with FIRST, most teams do not place their wheels on the extremeties of their frames, so this is applying to teams who have wheels inside the footprint of their frames.


See the *crude* picture below:

....................FRAME
.....------------------------------------
.....l......*.................*
..a l.......*.....WHEEL..*
.....l.........*............*
.....l<------> ****.............------->x
..........b

a = distance from edge of frame to ground
b= distance (in the x direction) from edge of frame to contact point wheel makes with ground (assumed to be the radius of the wheel).

Hopefully this clears it up a bit!
