Hmm…perhaps you could mount this on a drone, and take selfies!
More seriously, consider all of the demos these days of large numbers of drones set to fly formation through a number of simple “insect like” rules. Those drones are all programmed to more or less work together through cooperative (though simple) rules. I could see this as something more sophisticated, but similar. Imagine if you have a security drone for your property, and you want to monitor other drones which are not invited. If you added code to fly formation with a non-cooperating drone, or to “orbit” the other drone (perhaps while taking pictures of it or examining the radio spectrum which might come from it), then this would be even more interesting.
If you’ve ever seen any of the television series BattleBots, I think it would be a lot of fun to build a bot such as those, but one which flies and can dogfight other drones or ground bots. This is an interesting “key ingredient”.
