Autoshifting is really, tricky.
There are so many instances where the robot can't possible know that shifting would be an issue at the current point in time. When you're turning, drifting to a stop, or grabbing a game piece, you don't want to shift.

Yes, it's possible, but I think it may be more efficient for the driver to just remember where the shift button on the joystick is, and the coach can instruct the driver on what gear to be in (if the driver is too busy to make the decision himself.)
I should've been more thorough; You don't just do a greater/less than check on current, you need to look at it over time (how it's changing), along with applied voltage to make intelligent decisions.
