Singapore’s cyborg cockroaches could save your lifeーNHK WORLD-JAPAN NEWS

Key Concepts

• Cyborg Insects: Insects augmented with electronic devices for specific tasks.
• Madagascar Hissing Cockroach: The species of cockroach used in this research due to its size and wingless nature.
• Infrared Camera: Used to detect human body heat.
• Antenna: For wireless communication and data transmission.
• Electrical Stimulation: Gentle electrical signals sent to sensory organs to control movement.
• Disaster Search Operations: The primary application for cyborg insects, particularly in collapsed buildings.
• AI-Powered Assembly Line: For rapid and accurate outfitting of cyborg insects.

Cyborg Cockroaches for Disaster Search

1. Introduction to Cyborg Cockroaches

• Problem: A massive earthquake in Myanmar in March resulted in over 3,800 deaths, highlighting the need for effective search and rescue operations in collapsed structures.
• Innovative Solution: Researchers are utilizing cyborg cockroaches as unlikely helpers for survivor searches.
• Technology: These cockroaches are fitted with a tiny backpack containing an infrared camera and a communication antenna.

2. Development and Motivation

• Lead Researcher: Professor Sato Hirotaka from a university in Singapore.
• Motivation: The 2011 tsunami and earthquake in Japan inspired Professor Sato to research the use of small insects for disaster search.
• Insect Choice: The Madagascar Hissing Cockroach (approximately 6 cm long) was chosen because:
  • Its large body is suitable for carrying electronic devices.
  • It is wingless, making it easier to control remotely as it cannot fly.

3. Functionality and Control Mechanism

• Movement Control: Researchers use a controller to send gentle electrical signals to the cockroach's sensory organs, instructing its movements.
• Detection System:
  • The infrared camera on the cockroach's back detects human body temperature.
  • Upon detection, a system on its back beeps and wirelessly sends an alert to a remote rescue team.

4. Advantages of Using Insects in Disaster Zones

• Navigating Complex Environments: Insects can navigate small gaps and harsh conditions (water, dust) that are difficult for current small robots.
• Natural Resilience: Insects are naturally adapted to survive in challenging natural environments.
• Quote: "Insects live in nature and can survive in harsh conditions like being exposed to water and clouds of dust. So, the key of this research is to utilize their characteristics."

5. Real-World Application: Myanmar Earthquake

• Deployment: Ten cyborg cockroaches were deployed in earthquake-hit areas in Myanmar in March.
• Objective: To assist search teams from Singapore in locating survivors in collapsed buildings.
• Specific Use Case: "You can see there's a small gaps uh in between that uh the search docks and the civil defense personnel cannot go inside. So that's where we deploy these small little so it can crawl inside the small little gaps and to search for survivors."
• Outcome: No survivors were found during this specific mission.

6. Future Prospects and Scaling Up

• Government Optimism: The Singaporean government is optimistic about the future use of this technology.
• Future Goal: To scale up the technology and support overseas humanitarian operations by the Singapore Civil Defence Force (SCDF) in future disasters.
• Quote: "We definitely want to scale up so in future touch if anything any disaster happens. We hope to support SCDF, Singapore SCdF in their operations overseas in terms of humanitarian operations to search of survivors."

7. Automation and Efficiency

• Automated Assembly Line: Researchers are developing an automated assembly line to expedite the deployment of cyborg cockroaches.
• AI Integration: An AI-powered system recognizes insect bodies and attaches backpacks with increased speed and accuracy.
• Time Efficiency:
  • Outfitting one cyborg cockroach now takes approximately one minute.
  • Manual outfitting previously took over an hour.
• Researcher's Vision: "I want to elevate this technology beyond just papers and academic presentations and put it into practical use to save people."

8. Conclusion and Ultimate Goal

• Ongoing Research: Researchers are actively working to refine this technology.
• Ultimate Goal: To ensure that rescuers can effectively find everyone who goes missing in a disaster.

Synthesis/Conclusion:

This research presents a groundbreaking approach to disaster search and rescue by transforming common insects into sophisticated cyborgs. By leveraging the natural resilience and maneuverability of Madagascar Hissing Cockroaches, augmented with infrared cameras and communication systems, researchers aim to access areas inaccessible to humans and conventional robots. While initial deployments have not yet yielded survivor rescues, the technology shows significant promise, with ongoing efforts focused on automation and scaling up for future humanitarian operations. The ultimate objective is to enhance the effectiveness of rescue efforts and save lives in disaster situations.
