I know some people have implemented a remote CO2 dump which I think is a good idea. The only disadvantages I can see are that it would require me to recharge my gas reservoir after every fight, rather than every 2 fights and it would also take quite a while to vent my reservoir through the regulator, so would increase the time between fights. Safety comes above these concerns, of course.

The standard removable links as supplied by Technobots require a surprising amount of force to disconnect and you would need a big solenoid to pop them out. I would also be worried about such a device activating accidentally while my hand was in the robot removing the link - it could lead to a broken finger.
