Agreed, I have to get back into this mind set, lab conditions are good only in the lab. The load current should remain fairly constant, but the voltage will be all over the map, you may look into pre-built regulated power supplies. I am unsure whether they are mad for this low of a voltage or even if they are whether they would be cheap enough.

Be sure before you hook it up to anything, have someone who is very knowledgeable with electrics look it over, if you are not comfortable doing it. Also be sure to hook a meter to it and make sure that the output is within tolerances of the device being plugged into it, do this while the robot is under simulated playing conditions.
