Remote Control Cockroach Cyborgs
“Our aim was to determine whether we could create a wireless biological interface with cockroaches, which are robust and able to infiltrate small spaces,” says Alper Bozkurt, an assistant professor of electrical engineering at NC State and co-author of a paper on the work. “Ultimately, we think this will allow us to create a mobile web of smart sensors that uses cockroaches to collect and transmit information, such as finding survivors in a building that’s been destroyed by an earthquake.
“Building small-scale robots that can perform in such uncertain, dynamic conditions is enormously difficult,” Bozkurt says. “We decided to use biobotic cockroaches in place of robots, as designing robots at that scale is very challenging and cockroaches are experts at performing in such a hostile environment…”
…The new technique developed by Bozkurt’s team works by embedding a low-cost, light-weight, commercially-available chip with a wireless receiver and transmitter onto each roach (they used Madagascar hissing cockroaches). Weighing 0.7 grams, the cockroach backpack also contains a microcontroller that monitors the interface between the implanted electrodes and the tissue to avoid potential neural damage. The microcontroller is wired to the roach’s antennae and cerci. — North Carolina State University
