  • Most of the time, people are not happy to see cockroaches.
  • 2
  • The insect is known around the world as a pest - a creature that causes problems for people.
  • 3
  • However, the cockroach is a useful insect for research scientists.
  • 4
  • And they could one day be used to help find survivors after major earthquakes.
  • 5
  • Scientists in Japan have been working on a system that they can attach to the insects that permits remote control.
  • 6
  • Kenjiro Fukuda leads a team at the Thin-Film Device Laboratory at Riken, a company that does scientific research.
  • 7
  • The team created a thin solar cell they can attach to the body of a cockroach. It is thinner than a human hair.
  • 8
  • The cell permits the cockroach to move freely but it sends signals to organs that control the insect's legs.
  • 9
  • The scientists believe they can control the cockroaches from a long distance.
  • 10
  • This means they will be able to send the insects into a disaster area, such as a building destroyed by an earthquake.
  • 11
  • The small insects can get into places that humans and even rescue robots cannot reach.
  • 12
  • With the right equipment, they could be used to help find survivors stuck under broken pieces of buildings.
  • 13
  • The work advances a project done by scientists in Singapore.
  • 14
  • Fukoda said the problem with rescue robots is their batteries run out quickly.
  • 15
  • The insect, however, moves on its own.
  • 16
  • The battery only sends a signal that makes the cockroach move, so it lasts much longer.
  • 17
  • "The electricity required is nowhere near as much" as what is required for rescue robots, Fukoda said.
  • 18
  • The research team is using hissing cockroaches from Madagascar.
  • 19
  • Those cockroaches are big enough to carry the equipment and strong enough to get back on their feet if they fall over.
  • 20
  • Although the research is going well so far, the technology is not fully ready for use in the real world.
  • 21
  • For example, in a recent demonstration, the scientists sent signals to a cockroach that caused it to move to the left.
  • 22
  • However, the cockroach moved in circles when they sent a signal telling it to move right.
  • 23
  • The next step is to see if there are small cameras and sensors that can be placed on the cockroach's back.
  • 24
  • The team created the first test backpack using material purchased from an electronics market in Tokyo for only $35.
  • 25
  • Even if the thin solar cell is not able to be used in rescue missions, Fukoda said there could be a number of future uses.
  • 26
  • For example, the cells could be used in clothing to measure a person's health.
  • 27
  • The cells could also be added to an umbrella.
  • 28
  • Used in this way, the cells could help generate enough power to charge a mobile phone.
