NTU, Waseda Develop 3-Hour Diving Suit for Cyborg Cockroaches for Disaster Rescue

Q: After their 2025 earthquake deployment, what is the next critical upgrade for these tiny amphibious cyborg rescuers?

The next critical upgrade is a smarter life-support system: actively controlled oxygen delivery inside the cockroach’s diving suit. The current suit already lets the cyborg cockroaches survive underwater and in low-oxygen spaces for up to three hours by using a passive chemical reaction to release oxygen. But after their reported use in the 2025 Myanmar earthquake response, researchers say the key step forward is to make that oxygen system adaptive rather than fixed. That means adding miniature oxygen sensors and micropumps so the suit can monitor oxygen levels in real time and precisely meter hydrogen peroxide into the manganese-dioxide reactor. In practice, this would let the robot match oxygen supply to the insect’s activity level, improving endurance, reliability, and safety during missions in rubble, flooded passages, or carbon-dioxide-filled voids. Beyond that, the broader field upgrade for real disaster deployment is to add onboard sensors and navigation tools. The study notes future versions could carry equipment for inspection and guidance, helping the amphibious cyborgs do more than just enter tight spaces—they could also detect hazards, map routes, and send back useful information to rescuers. So the immediate technical priority is dynamic oxygen regulation, with sensing and navigation integration as the next step toward practical field use.

NTU Singapore and Waseda University researchers built a flexible diving suit that kept cyborg cockroaches active underwater for up to three hours, extending their use in flooded or oxygen-poor disaster zones.
The suit pairs a waterproof shell with four silicone tubes and a 3D-printed oxygen tank, where manganese dioxide and diluted hydrogen peroxide generate oxygen for the insects' spiracles.
Tests on Madagascar hissing cockroaches showed the suited insects crossed carbon-dioxide and water-filled tunnel sections, while unsuited controls suffocated in about two minutes.
Implanted electronics also let one cockroach squeeze through a 2-centimeter-high underwater crevice, highlighting an advantage over bulkier small robots in rubble, drains and collapsed structures.
The Nature Communications study remains early-stage, but the team aims to add sensors, cameras and navigation tools for future search-and-rescue and infrastructure inspection missions.
