Whats the latest and greatest new technology for UAVs being developed right now? I've been using UAVs for aerial videography for the past 2 years. It seems like the industry is constantly innovating, so much so that's it hard to keep track of. I wanted to start a thread where developers, manufactures and UAV enthusiast could post about new projects their working on or cool new tech they've seen. I know there's a lot going on in the way of sense and avoid tech, Lithium Carbon batteries, mini drones and 3D mapping seems to be getting easier. Please share things you find cool.
