Researchers have developed a miniature 3D-printed diving suit that allows cyborg cockroaches to operate both on land and underwater, opening new possibilities for search-and-rescue missions, infrastructure inspections, and disaster response.
The project combines additive manufacturing, robotics, and biology to create a new type of biohybrid system. Instead of building a robot entirely from mechanical components, researchers equipped living cockroaches with lightweight electronic backpacks and a custom-designed 3D-printed wearable that enables them to function in flooded and low-oxygen environments.
The diving suit consists of a flexible waterproof shell, miniature 3D-printed connectors, silicone tubing, and a tiny oxygen-generation module. Rather than carrying a limited oxygen supply, the system continuously produces oxygen through a chemical reaction, delivering it directly to the insect’s breathing openings while submerged. This innovative design allows the cockroaches to remain underwater for up to three hours while continuing to crawl and navigate obstacles.
To evaluate the technology, the research team conducted a series of underwater experiments using water tanks and 3D-printed obstacle courses that simulated flooded environments. The cyborg cockroaches successfully swam, crawled through narrow passages, and carried their electronic payloads while maintaining mobility with only a slight reduction in speed compared to movement on land.
Researchers believe this technology could play an important role during natural disasters, where conventional robots often struggle to reach confined or submerged spaces. Equipped with cameras and environmental sensors, future biohybrid insects could inspect damaged pipelines, flooded tunnels, collapsed buildings, sewer systems, and other hazardous locations that are difficult or unsafe for human responders.
The project also demonstrates how advanced 3D printing enables the creation of highly specialized miniature components that would be difficult to manufacture using conventional methods. By producing lightweight, customized parts with precise geometries, additive manufacturing continues to expand the possibilities for next-generation robotics and wearable technologies.
As research into biohybrid robotics continues to evolve, innovations like this 3D-printed diving suit highlight the growing role of additive manufacturing in solving complex engineering challenges. From disaster response and environmental monitoring to infrastructure inspection, 3D printing is helping bridge the gap between biology and robotics, creating entirely new capabilities for future autonomous systems.
