Inter-robot communication? Did somebody just say laser tag?
Seriously, though, I'm thinking of the real world. You've got some things that are strictly human-controlled and some things that are strictly autonomous. But then you've got some things that have some human input, but do a lot of the stuff on their own.
So imagine this. Autonomous mode ends, and your operators take over, operating four push-button switches to handle the entire robot operation for the next N seconds. Teams can program their robots to react to those switches however they choose, but they can only use those four switches; joysticks and other switches are still disabled. I assume this would either take some trickery on IFI's part, or FIRST ordering a lot more penalty flags.
If this actually works, I will kindly ask that all rocks, baseball bats, torches, and pitchforks be kept away from me. Thank you for your cooperation.
