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 tested in a simulated environment with fog and spooky lights.
The robotics lab at Worcester Polytechnic Institute isn't hosting a Halloween party, despite the fog machine and fake bats.
