the current IC rules do have a lot of areas to look into new stuff, but i think new rules would quickly appear if needed, when people begin to build robots along these lines.

as the rules stand, i think most of your plans could be blocked by not allowing pressurized or pumped fuels, which is in the rules at the mo.

which is a shame as i have some evil plans myself that will never see the light of day, but its for the greater good i suppose
