Researchers from Nanyang Technological University in Singapore and Waseda University have developed remote-controlled cyborg cockroaches that can now operate underwater by wearing miniature 3D-printed diving suits. The lightweight system generates oxygen through a chemical reaction and delivers it directly to the insects' breathing openings, allowing them to survive and move underwater for up to three hours without impairing their natural mobility. The technology builds on previous work that enabled researchers to steer swarms of cockroaches remotely using tiny electronic implants.
The amphibious cyborg insects are designed to support search-and-rescue missions in environments inaccessible to conventional robots, such as flooded buildings, collapsed tunnels, drains, and other confined spaces. Because the insects rely on their own muscles for movement, they require far less energy than similarly sized robots while remaining highly agile. The research team also envisions future applications in infrastructure inspection and, eventually, exploration of extreme environments, including planetary missions where lightweight, energy-efficient biohybrid systems could offer significant advantages.
