thanks a lot for the help. I might try playing around with that. I'm doing a combat obstacle course. It's pretty much a free-for-all. I think there is a simpler way in this case though. the other robots have to be programmed to recieve a remote signal "message() ==1" to shut them down temporarily so if they don't immediately disable their IR imput I'll be able to broadcast this message and shut them down.

I will try some of the more complicated stuff you talked about though. Thanks a lot!
