With all this wireless technology in existence these days, can't you just use wireless CO2 or something?

On a serious note - although I'm not a part of the flipping brigade - a tool seems and always has seemed a sensible option for arming up. Anything that helps to minimise risk to the arena marshal/roboteer should be considered. I remember someone saying that a disadvantage of using a tool for dis-arming was that if the area where the tool is used was damaged during a fight and it became impossible to insert the tool, you'd have trouble turning off the gas, but then again, the current accessible hole method is just as susceptible to sustaining damage that can render access difficult.

Again it's been mentioned before, but a universal tool would be a cert in my eyes, save the poor arena marshals having to keep a hold of umpteen different tools for umpteen different robots during a fight.

Is this be something people would be looking to implement in the FW class too, or is it more desirable in the HW class due to the heavy and more lethal nature of the machines?
