Researchers have equipped cockroaches with custom-fitted 3D-printed diving suits, enabling the insects to walk underwater for up to three hours without harm. The technology represents a step forward in creating cyborg insect swarms capable of exploring hazardous environments.
The suits, engineered to fit individual cockroaches, maintain an air pocket around the insects' bodies while they navigate submerged terrain. Scientists fitted the gear onto remote-controlled cockroaches, demonstrating that the animals could move effectively across underwater surfaces and return to the surface safely afterward.
The research builds on earlier work in biohybrid robotics, where researchers have augmented insects with electronic components for remote control and navigation. Cockroaches serve as ideal candidates for this work because of their small size, durability, and ability to squeeze through tight spaces.
The underwater capability opens practical applications for disaster response. After earthquakes, floods, or building collapses, cyborg insect swarms could infiltrate confined spaces too small or unstable for conventional robots. They could scout for survivors, map structural damage, or detect chemical hazards before larger rescue equipment enters.
The researchers also suggest potential use for planetary exploration. The suits could allow insect swarms to investigate subsurface environments on Mars or other planets where liquid water might exist, reaching locations that wheeled rovers cannot access.
The approach demonstrates how biological systems combined with engineered enhancements can overcome environmental challenges that limit conventional robotics. Unlike bulky submersible robots, these cyborg insects require minimal power and can navigate complex terrain through natural movement.
Limitations remain. The suits work for relatively short periods. Scaling up to swarms for coordinated missions requires advances in controlling multiple insects simultaneously. The technology also raises questions about animal welfare, though researchers note cockroaches show no visible stress from the apparatus.
