In a breakthrough that blends biology and robotics, researchers at the University of Osaka have created a new type of insect cyborg that can navigate autonomously鈥攚ithout wires, surgery, or stress-inducing electrical shocks. The system uses a small ultraviolet (UV) light helmet to steer cockroaches by taking advantage of their natural tendency to avoid bright light, especially in the UV range. This method not only preserves the insect's sensory organs but also maintains consistent control over time.

The work is in the journal Advanced Intelligent Systems.

Traditional cyborg insects rely on electrical stimulation, which often involves invasive surgery and can lead to damage of critical sensory organs. Over time, these electrical signals also become less effective as the insect's body adapts鈥攁 phenomenon known as habituation. In contrast, the UOsaka team's system uses negative phototaxis, a behavior in which insects instinctively move away from UV light. By shining light into either eye, researchers could steer the cockroach left or right, with no need for direct contact with nerves or muscles.

The team fitted cockroaches with UV-light helmets and wireless sensor backpacks that detect when they stop moving. If motion ceases, UV light is activated to prompt movement. This smart control reduced unnecessary stimulation and saved energy.

In tests, cyborg insects showed consistent responses during 150 trials without habituation. In a maze-like environment, 94% successfully escaped鈥攃ompared to just 24% of normal cockroaches.

According to the research team, this study is the first to demonstrate successful behavior control of insect cyborgs using only their natural sensory system鈥攚ithout any electrical stimulation. The new Bio-Intelligent Cyborg Insect (BCI) model significantly reduces the physical burden on the animal and increases the reliability of movement control in complex environments.

Keisuke Morishima, who led the study, emphasized the importance of working with鈥攔ather than against鈥攖he insect's natural biology.

"Instead of overriding the insect's brain, we're guiding it through its own senses. That makes the system safer, more stable, and more sustainable," he said.

This gentle, light-based method opens the door to low-burden, bio-hybrid navigation systems with potential applications in fields such as disaster search and rescue, environmental monitoring, and surveillance鈥攅specially in places too small or dangerous for conventional robots.
