Summary
A waterproof suit let cyborg Madagascar hissing cockroaches survive and move underwater for up to three hours in lab tests, opening a possible new tool for flooded search-and-rescue zones.
The system pairs a soft shell with four silicone tubes and a 3D-printed oxygen tank, where manganese dioxide and diluted hydrogen peroxide generate oxygen for the insects' spiracles.
Researchers said the design preserves the cockroach's natural mobility while extending operation into submerged and low-oxygen spaces that conventional cyborg insects cannot normally handle.
The team sees potential use in flooded pipes, drains and tunnels, and plans to add sensors and navigation before testing the suit in simulated disaster environments.
How will cyborg cockroaches transmit life-saving data from deep within flooded disaster zones?
Could this diving suit be adapted for more complex organisms to perform advanced underwater missions?
As living creatures are turned into robotic tools, where do we draw the ethical line for this technology?
3-Hour Underwater Cyborg Cockroaches: Transforming Disaster Response with Biohybrid Robotics
Overview
Engineers from Nanyang Technological University and Waseda University have achieved a major breakthrough by developing a flexible diving suit for cyborg cockroaches, as published in Nature Communications in June 2026. This innovation transforms the Madagascar hissing cockroach into an amphibious bio-hybrid robot, allowing it to survive and operate underwater for up to three hours. The specialized suit enables these cyborg insects to move seamlessly between dry and wet terrains, greatly expanding their usefulness in search and rescue missions. This advancement marks a crucial step in reaching disaster zones that were previously inaccessible to both humans and traditional robots.
