What is the power rating of the ballast? According to Wikipedia 100 watt ballast is capable of killing someone at that voltage. Even at one watt the ballast is still dangerous because Wikipedia states that you can't let go. Unfortunately, the values appear to vary wildly between website to website on how much current can kill.

In order to up the voltage you must reduce the current (through a constant resistance). There is no rule against having higher than 12 volts on the robot (or lower, which by your definition would not be allowed either), just that the electrical supply must come from the 12 volt battery.

This doesn't sound right. You don't necessarily need a resistor to boost the voltage to higher than the supply. In fact you might be confusing the fact that a florescent tube actually has negative resistance at a certain point and a resistor is needed to ensure that it doesn't just keep on trying to draw more and more current.
