Researchers at Worcester Polytechnic Institute are developing tiny drones that use echolocation, like bats, to navigate in dark and challenging conditions.
The aerial robots are being designed for search and rescue missions, and are capable of operating in conditions that would be difficult for traditional drones.
Don't be fooled by the fog machine, spooky lights and fake bats: the robotics lab at Worcester Polytechnic Institute isn't hosting a Halloween party.
