A new 3D-printed diving suit allows remote-controlled cyborg cockroaches to breathe and navigate underwater for up to three hours during search-and-rescue missions.
When natural disasters strike, finding survivors trapped in collapsed buildings or flooded ruins is a race against time. Traditional rescue robots are often too bulky to squeeze through unstable debris, and battery-powered micro-bots can quickly run out of power. To solve this, scientists have turned to one of nature's most resilient survivors—the cockroach—equipping them with high-tech backpacks and now, custom-made "scuba suits" to navigate flooded disaster zones. This bio-hybrid technology could soon give emergency response teams a low-cost, highly efficient tool to find people trapped where humans and machines cannot reach.
What Happened
Researchers from Nanyang Technological University in Singapore and Waseda University in Japan have successfully developed a waterproof, 3D-printed "diving suit" for cyborg cockroaches. The study, published in the journal Nature Communications, details how these specialized suits allow the insects to maintain buoyancy and oxygen levels while submerged underwater for up to three hours. Without the suit, a cockroach can only survive underwater for a few minutes.
The bio-hybrid system uses Madagascar hissing cockroaches, chosen for their resilience and ability to squeeze through tight, unstable gaps. The insects are fitted with tiny electronic controllers that send mild electrical signals to guide their movements.
To make them amphibious, scientists designed a tiny 10x10 millimeter backpack. Inside the 3D-printed tank, a sponge coated with a manganese dioxide catalyst reacts with diluted hydrogen peroxide to chemically generate oxygen. This oxygen is then delivered directly to the cockroach's breathing holes, known as spiracles, through flexible silicone tubes. A strong adhesive holds the tubes in place and keeps water out of the insect's airways.
- Three-hour limit: The 3D-printed scuba suits allow the cyborg cockroaches to survive and navigate underwater for up to three hours.
- Chemical oxygen: Instead of carrying heavy pressurized air tanks, the suit uses a chemical reaction to produce breathable oxygen on the go.
- Compact design: The entire diving apparatus measures just 10x10 millimeters, light enough for the insect to carry without hindering its mobility.
- Real-world testing: Cyborg cockroaches have already been deployed in disaster zones, including search-and-rescue efforts following a 7.7-magnitude earthquake in Myanmar in March 2025.
- Muscle power: Unlike mechanical micro-robots that rely on heavy batteries, these cyborgs use the insect's own muscles for propulsion, extending operational endurance.
Why It Matters
In the immediate aftermath of earthquakes or heavy rains, disaster sites are often highly unstable and flooded. Blocked drains, narrow gaps, and water-logged rubble make it impossible for human rescue teams or traditional search dogs to navigate safely.
Cyborg cockroaches offer a unique advantage because they combine biology and technology. They possess natural instincts to navigate complex terrain and squeeze through gaps smaller than an inch. Because they rely on their own biological energy to move, they do not suffer from the sudden battery failures that plague fully mechanical miniature robots. By expanding their operating environment to include water, researchers have created a highly resilient, low-cost tool capable of operating across both land and water to locate survivors.
What Happens Next
The research team plans to continue refining the bio-hybrid technology to make the diving suits even more durable. Future iterations may include tiny sensors, such as infrared cameras, to help locate human heat signatures in pitch-black ruins. Scientists are also looking into ways to automate the steering process, allowing a swarm of cyborg insects to map out a disaster zone autonomously while sending real-time location data back to rescue crews.
What We Still Don't Know
- How will rescue teams reliably receive data and tracking signals from the cockroaches when they are deep underwater or buried under thick concrete rubble?
- What are the long-term effects of the electronic implants and the chemical oxygen generator on the health and lifespan of the cockroaches?
- How will the public and emergency responders react to the widespread deployment of remote-controlled insects in sensitive crisis situations?
