The latest in search-and-rescue tech: cyborg cockroaches

Researchers at North Carolina State University have developed a new way to control cockroaches, outfitting them with tiny microphones and trackers for potential future use in disaster zones.

The latest in search-and-rescue technology could fit in the palm of your hand, although it is just as likely to try to scurry out of it. 

Researchers at North Carolina State University have developed cyborg cockroaches to help locate survivors in the aftermath of a disaster. Equipped with backpacks loaded with tiny microphones and trackers, the bugs could be used to help lead rescuers to victims, according to a press release from NCSU.

NPR reports that the cockroaches can be controlled by tiny electrodes inserted into an area of the insect's brain responsible for controlling the front legs.

The researchers have also developed technology that can be used as an “invisible fence” to keep the cockroaches in the disaster area.

“I’m always open to additional assets at a rubble site,” says Harry Oakes SAR Coordinator for International K-9 Search and Rescue Services of Longview, Washington in an interview. “I was in Turkey back in ’99 after the quake and we found people alive 10 days later. But even though you locate the victim it can still take hours and hours to get to them. If cockroaches can get us there faster, then I’m all for it.”

Roger D. Kamm, a professor of biological and mechanical engineering at MIT, says in an interview, “This is very exciting work that’s being done. There are a lot of biological systems we can’t reproduce. Just the cockroach’s ability to easily and quickly crawl up walls, into confined spaces is hard to reproduce in a robotic creation.”

The research team has created two types of customized backpacks using microphones. One type of 'biobot,' as the cybernetically augmented bugs are known, has a single microphone that can capture relatively high-resolution sound from any direction to be wirelessly transmitted to first responders, according to the release. The second type is equipped with an array of three directional microphones to detect the sound's source. The system worked well during laboratory testing, the researchers say.

The project is funded by National Science Foundation CyberPhysical Systems Program and has a long-term goal of both mapping disaster areas and pinpointing survivors.

The researchers is also working with collaborator Mihail Sichitiu of  NCSU to develop the next generation of biobot networking and localization or “invisible fence” technology.

This is significant because it can be used to keep biobots at a disaster site and to keep the biobots within range of each other so that they can be used as a reliable mobile wireless network.

“Of course a cockroach will never replace a search-and-rescue dog or have the same capabilities the dog has,” Says Mr. Oakes. “On the other hand, the dogs can’t do what the cockroaches can do.

“I think we’re going to see more interface and integration between biology and robotics as a result of this type of research,” Mr. Kamm says. “Being able to redesign living organisms to turn into biological robots we can control is very exciting.”

What is the Monitor difference? Tackling the tough headlines – with humanity. Listening to sources – with respect. Seeing the story that others are missing by reporting what so often gets overlooked: the values that connect us. That’s Monitor reporting – news that changes how you see the world.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
