Osaka University Proposes ‘Insect Synergy Circuit’ for AI-Driven Cyborg Cockroach Control

Asia Research News Japan

Overview

Researchers at Osaka University have proposed a novel concept, the ‘Insect Synergy Circuit (ISC),’ where AI interprets insect biological signals to enable more cooperative control. The team developed a wearable backpack for Madagascar hissing cockroaches that simultaneously measures heart rate, low-frequency nerve signals, and body movements. This system estimates the insect’s environment-related internal state, allowing guidance while minimizing unnecessary stimuli.

Research Background and Challenges in Cyborg Insects

Research into cyborg insects holds significant promise for applications in disaster relief, environmental monitoring, and hazardous area exploration, particularly in places inaccessible to humans. However, conventional cyborg insect systems typically involve unilateral external commands from humans, without adequately considering the insect’s own biological state or autonomous responses to its environment. This approach often leads to excessive stress on the insects and difficulties in efficient behavioral guidance. The research team at Osaka University aimed to overcome these challenges and establish a more cooperative relationship with insects.

‘Insect Synergy Circuit (ISC)’ and AI-Driven Biosignal Interpretation

The new concept proposed by Osaka University researchers is the ‘Insect Synergy Circuit (ISC).’ This system allows AI to interpret an insect’s biological signals in real-time, understanding its internal state and intentions, thereby guiding its movements towards human-desired directions while respecting its autonomy. For Madagascar hissing cockroaches, the research team developed a wearable backpack capable of simultaneously measuring heart rate, low-frequency nerve signals, and body movements. The AI analyzes data from sensors embedded in this backpack to estimate the cockroach’s ‘environment-related internal state.’ For instance, the AI can determine if the cockroach is experiencing stress or how it intends to react to a specific stimulus.

Cooperative Control and Future Outlook

The ISC system enables more natural guidance of the cockroach’s movements, reducing unnecessary external stimuli based on AI’s estimation of the insect’s internal state. This approach mitigates insect stress and enhances the efficiency of guidance. For example, it can encourage a fatigued insect to rest or issue the next behavioral command at an optimal time, realizing more intelligent control. This ‘Insect Synergy Circuit’ represents a novel approach to bio-machine integration and is expected to significantly impact the evolution of cyborg insect technology. In the future, it is anticipated to lead to the development of cyborg insects with more complex mission capabilities and contribute new insights into the design of interfaces between biological systems and AI.
