WORCESTER, Mass. — Don't be fooled by the fog machine, spooky lights and fake bats: the robotics lab at Worcester Polytechnic Institute lab isn't hosting a Halloween party.

What You Need To Know • Researchers at Worcester Polytechnic Institute are developing tiny drones inspired by bats for search and rescue missions • The aerial robots use echolocation, like bats, to navigate in dark and challenging conditions • Assistant professor Nitin Sanket and his team aim to create small, affordable, and energy-efficient drones that can operate where and when current drones can't • While drones are becoming more common in search and rescue, Sanket and researchers elsewhere want to move beyond the manually operated individual robots being used today

Instead, it’s a testing ground for tiny d
