Researchers at Nanyang Technological University in Singapore have successfully tested an army of remote-controlled cyborg cockroaches in a sandy test area, as reported by New Scientist. These experiments could pave the way for deploying such swarms in real-world scenarios, such as locating missing persons after natural disasters.
The team equipped Madagascar hissing cockroaches with "backpacks" that allowed a central computer to control them via electrodes attached to their sensory organs. Commands were relayed to the cockroaches, directing them to move left or right. This technology enabled researchers to manage a swarm of 20 cyborg roaches, maneuvering them as a cohesive unit across the test site.
The research, detailed in a yet-to-be-peer-reviewed paper, demonstrated the potential for these cyborg insects to perform tasks like sensor readings, object hunting, or search-and-rescue missions. In tests, the cockroaches navigated around obstacles and even assisted each other when overturned, showcasing their ability to operate in challenging environments.
During the experiments, the central computer designated certain cockroaches as leaders, which the others followed. This hierarchical control structure allowed the swarm to move efficiently and adapt to their surroundings. The researchers envision these swarms aiding in disaster recovery by searching through rubble and taking environmental readings. A larger robot could support the swarm by providing recharging stations, food, and water.
The team, led by mechanical engineering professor Hirotaka Sato, is already exploring the possibility of turning rainbow crabs into cyborgs to enhance the capabilities of their insect army. "The crab can help the cockroaches," Sato told New Scientist. "We are working on such kinds of things, but it takes time."
