If we opt to use line followers (I'm thinking an ultrasonic sensor and a gyro for dead-straight tracking is as good as we'll need), we'll probably cut a hole in our electronics board and mount them a little above the bottom of the front of the chassis.

One of the really cool things about this transmission is the belt reduction - we can adjust with a new belt and output pulley between 9 and 14 FPS without taking up as much space as a chain run would. It also lets us mount our motors in a very compact configuration - the two-motor model is literally 3 inches from the ground.
That being said this is a valid concern - does anyone know how I could predict battery discharge rates using math? I have no idea how to do it.

Our drivetrain's CG last year was about 5 inches from the ground.
This year, it's just under an inch and a half.
With the 9 foot tall arm we're working on, that could be pretty important.
