iRobot's various military robots are already capable of packing some weaponry, but it looks like Metal Storm is set to give their arsenal a considerable boost, with it recently demonstrating its remotely-operated FireStorm weapons system on one of iRobot's standard Warrior platforms. That system essentially makes the ammunition the only moving part in the weapon, with it able to fire bullets electronically at a rate of thousands of rounds per minute (or "theoretically" even up to a million), which Metal Storm says makes the system ideal for a whole range of applications including, somewhat ominously, "crowd control."
