Cyborg Cockroaches Equipped with Oxygen Suits Can Operate Underwater for 3 Hours

Executive Briefing

• Researchers fitted Madagascar hissing cockroaches with waterproof suits containing chemical oxygen generators, enabling underwater mobility.
• Extends prior NTU cyborg insect research, which previously demonstrated swarm navigation with 20 insects in confined spaces.
• Chemical oxygen generation avoids bulky air tanks, addressing the payload and power constraints critical at insect scale.
• Biohybrid insects could theoretically reach flooded voids, pipes, and debris gaps where small conventional robots struggle.
• Study published in Nature Communications stops short of real disaster-zone deployment, keeping claims measured and restrained.
