I'm picturing putting two little prongs on the front of this and having it use image recognition to fly up to electrical outlets and recharge itself while hovering.
Then it could fly indefinitely.
I guess you'd need it to carry an AC/DC transformer though? Too heavy?
I've heard ideas for flying robots that would hook themselves onto power-lines like birds (or maybe more like bats I guess) and charge themselves with induction from the line.
Probably several kinds of illegal, but it would be pretty neat.
There are examples of wireless recharging [1], and UAVs perching on power lines for recharging [2]. Apologies for the self-indulgent links -- I wrote the articles, so they were easy for me to locate. ;-)
