TOKYO, JAPAN-- What do you do when you see a cockroach? Do you hit it with a newspaper? Do you step on it?

When researchers at Tokyo University see a cockroach,they take the remote control and make the cockroach turn around,run left or right,or go forward.These scientists are changing the cockroaches into robots. Each cockroach has a very small pack that has a microprocessor in it. Then researchers can send signals from the remote control to the packet. The signals control the movements of the cockroaches.

Why does anyone want to control a cockroach? "Insects can do many things that people can't,” says Isao Shimoyama, head of robot research at Tokyo University. In a few years, he says, these robot insects will carry very small cameras. They will be able to move through earthquake rubble to look for people or move under door to find information about someone.

This may seem strange, but the Japanese government thinks the research is very important. The government is giving the scientists $5 million for this research.

First, the researchers breed hundreds of cockroaches. They use only the American cockroach because it is bigger and stronger than other cockroaches. Then they choose the best cockroaches and remove their wings and antennae. They put small packets where the antennae were. The packets weigh about three grams, or about two times the weight of the cockroaches themselves. “Cockroaches are very strong,” says Ralph Holzer,who is a researcher at Tokyo University. "They can lift 20 times their own weight.”

With a remote control, the scientists send signals to the packets. When a cockroach gets the signal, it moves. The problem is that the cockroaches don' t always move in the right direction.

The Olympic Games and Paralympic Games are a major international sport festival held every four years. The Games are separated into Summer and Winter editions, and new mascots (吉祥物) appear at each Games as colourful and cheerful representations (代表) of the country and culture in which the Games are held.

We finally know the mascots of the 2020 Tokyo Olympic and Paralympic Games. They are two robots with traditional Japanese designs.

The blue and white mascot is for the Olympic Games. It has a strong sense of justice (正义感) and has the power to move around very quickly. The other mascot is for the Paralympic Games. It is pink and white. It also has a special power to talk with stones and the wind and move things with its mind, the BBC reported.

Three sets of mascots were shown to primary school students. They decided the final mascots. More than 205,000 classes helped to select them. It was the first time in Olympic history to ask primary school students to pick the mascots. The mascots will get their names this summer. The winning Mascots will take part in all kinds of events up to and throughout the Tokyo 2020 Games.
