Quadrotors Turned Into Flying Wireless Battery Chargers
Cords are terrible, horrible things. Some of you may remember back to ancient times, when everything was corded and nobody was able to leave their houses. Ever. We've come a long way since then, what with wireless communication and batteries that don't totally suck, but really, batteries do still kind of almost totally suck.
Whenever you have anything that needs to survive away from the electrical grid for an extended period of time (whether it's a cellphone or a sensor), batteries are inevitably the limiting factor, and roboticists from the NIMBUS Lab at the University of Nebraska–Lincoln have solved the problem with a quadrotor that can fly around and wirelessly charge up electronics for you.
