Japan sends robots into Fukushima nuclear plant

David Hambling,

The team working to contain the meltdown at the Fukushima Daiichi nuclear plant now includes a robot. The machine, known as Monirobo ("Monitoring Robot"), was on the scene today, according to the Japanese newspaper Asahi Shimbun (in Japanese).

Monirobo is designed to operate at radiation levels too high for humans. The 1.5-metre robot runs on a pair of caterpillar tracks and has a manipulator arm for removing obstacles and collecting samples. Sensors include a radiation detector, 3D camera system and temperature and humidity sensors. It can be operated remotely from a distance of about a kilometre.

Monirobo weighs some 600 kilos and is limited to a speed of 2.4 kilometres per hour. It has to carry heavy shielding because many electronics, especially cameras, are highly vulnerable to the effects of radiation.

The robot was developed by Japan's Nuclear Safety Technology Centre in association with the Ministry of Economy, Trade and Industry after the Tokaimura nuclear accident in 1999 in which two workers died. Read more>>
