I can think of all the fun things you could do with flying robots. Though the judges would never let it pass, think about what would happen if it suddenly went haywire and went flying into the audience...
But then that got me thinking about something else. I started thinking about blimps and then about other inflatables. You know those inflatable life rafts? The ones that you pull a cord and then some super pressurized air inflates the raft in seconds? It sure would be fun to just strap one of those to the top of a robot, drive it to the other side in autonomous mode and then just pull the rip cord...
The funny thing would be if one of the enemy bots wasn't stuck on their side and then charges the thing with a pointy arm pointed straight at the inflated raft

. POW!
I'm really getting carried away aren't I? I need to get some sleep...
G'Night!
