From pesky insect into an ally of rescuers at disaster sites.

One variety of the insect, in particular, has the team at Nanyang Technological University excited – the Madagascar hissing cockroach.The species is large enough for Associate Professor Hirotaka Sato and his team at the School of Mechanical and Aerospace Engineering to equip the bug with a 5.5g “backpack” consisting of several sensors, including those that can warn of the presence of gases such as carbon dioxide.

Using a human detection algorithm, the team found that its cockroaches, or cyborg bugs, can distinguish between human and non-human subjects with 87% accuracy. “Since then, I have been seriously motivated to use my technology to contribute to Singapore’s rescue missions.” State-of-the-art miniature robots are also unable to last long enough for rescue operations due to high power consumption for movement, Ong said.

Madagascar hissing cockroaches are hardy creatures that are reportedly able to withstand 10 times more radiation than humans, and live up to seven days without their heads, as they are able to breathe through the spiracles on their sides.
