Its sort of like GSR, but that has more to do with the resistance and skin "persperation" in a sense.
I was going to try to describe EMG, but I think this site does it pretty well:

And photronist, you are right... per <R69> I would not be able to power this box unless I was able to get it from the joystick port. I dont think the box that I am using could do it, and Im not sure there is enough current in the output of the joystick port to support the amplifier Im using at the moment.
When I first came up with this idea, I thought of proposing a change to the FIRST rules, but I wanted to see how far I got. I dont think it would be feasible this year, as it would take quite a bit more time to do some advanced processing of the signals to make it usable in competition... So perhaps once I prove out the details, I'll make a pitch
