Smart Drones Fly Without GPS

Watch this video to see how Carnegie Mellon University’s Kenji Shimada made a smart drone that flies in environments without GPS signals — such as tunnels and construction sites — and avoids moving objects.

“To our knowledge, this is the first time 3D scanning with an autonomous drone has been done in dynamic, under-construction tunnel environments,” said Zhefan Xu , the lead Ph.D. student of the drone project.
