Why a Researcher Is Building Robots That Look and Act Like Bats
Search and rescue operations often take place in areas that are dangerous or nearly impossible for humans to navigate. That’s where robots that look and act like bats come in. Inspired by nature, a Worcester Polytechnic Institute (WPI) researcher, Nitin J. Sanket, is developing small, intelligent flying robots that use ultrasound — just like real bats — to detect obstacles and navigate through dark, smoky, or debris-filled environments. These bio-inspired machines could soon revolutionize how we conduct rescue missions worldwide.

How Do Bat-Like Robots Work?
Sanket’s bat-inspired robots are compact drones powered by AI-driven ultrasound systems. They emit ultrasonic signals and process the returning echoes using advanced algorithms to “see” their surroundings — even in low visibility. By filtering out noise and mapping obstacles within a two-meter radius, these drones move with precision and agility, making them ideal for search and rescue in disaster zones where traditional drones struggle.
Why Build Robots That Look and Act Like Bats?
According to Sanket, biology offers the best blueprint for innovation. Bats and insects achieve remarkable flight and sensing abilities with minimal computational power. By studying how these creatures operate, researchers can create smarter, smaller, and more efficient robots. The goal isn’t just to mimic nature but to enhance human capabilities — allowing machines to enter dangerous areas safely where people cannot.
What Could Bat-Inspired Robots Be Used For?
While the initial focus is on life-saving rescue missions, Sanket envisions broader applications. These AI-powered flying robots could assist in environmental monitoring, disaster recovery, cave exploration, and even agricultural tasks. Their lightweight design and adaptive AI make them suitable for missions requiring agility and real-time decision-making. As technology advances, such bat-like drones might soon become essential tools for first responders and scientists alike.
