Coined as cyborg bugs, the add-on device enables the critters to detect and warn others of the presence of gases like carbon dioxide.According to Assoc Prof Sato’s profile at, there is still a long way to go before artificial mini robots are really used for search and rescue missions in disaster-hit areas.

The system can be used for search and rescue missions as it is capable of autonomous navigation and detecting human presence in an unstructured environment.Researchers were able to pair a customised navigation control algorithm with the insect’s intrinsic navigation capabilities for exploring and manoeuvring complex terrains.

Meanwhile, an infrared camera attached to the backpack helps rescuers detect human presence at the site.It was mentioned that the low power consumption of the device allows it to operate for extended periods, with potential for application in real-life missions.

Furthermore, Madagascar hissing cockroaches can reportedly withstand up to 10 times more radiation than humans, survive up to a week without their heads, live around two to five years, and run at a speed of 200 mph (about 50 body lengths of itself in just one second).

“Singapore was the first country to dispatch their rescue team to Japan when the big earthquake hit (north-east Japan) on March 11, 2011,” said Assoc Prof Sato toThe Straits Times.“I was awarded Nanyang Assistant Professorship in the same year, and with the support from NTU, I started my cyborg robot research.”
