Japanese scientists create robot cockroaches

Scientists at the Japanese Riken Research Institute's Thin Film Devices Laboratory, led by Kenjiro Fukada, have developed a 4-micron-thick film for solar cells. It can become the basis of a device placed on the insects' abdomen and allow remote control of their movements. The researchers believe these cyborgs are well suited to searching for people under the rubble after earthquakes.

It is assumed that small “backpacks” with solar panels and electronics will be placed on the insects' backs so that they can move freely. The energy generated will be sufficient to remotely receive and transmit direction signals to the insect's sense organs. It is assumed that this work could become the basis for the creation of a device that will allow controlling insects that can penetrate hard-to-reach areas much more efficiently than robots.

“The batteries inside the small robots run out quickly, leaving little time for exploration. The main advantage of the [cyborg insect] is that when it comes to the insect’s movements, it moves, so less electricity is needed,” Kenjiro Fukada said.

In their work, the researchers used hissing cockroaches from Madagascar, because they are large enough to accommodate the necessary equipment and do not have wings that can become a nuisance. Even with a “backpack” and a film solar panel on their backs, cockroaches are able to overcome small obstacles and get on their paws if they roll onto their backs.

Scientists have a lot of work to do, including one aimed at making the insect control device as miniature as possible. It is hoped that because of this, additional sensors and even a camera can be placed on the insects' backs. A recent demonstration of the technology used a prototype “backpack” that cost just $35 in components.
