Japanese
nuclear reactor maker Toshiba on Wednesday unveiled a remote-controlled robot
resembling a headless dog that they hope will be used at the battered Fukushima
power plant.The tetrapod, which weighs 65 kilograms (143 pounds) and is about
one metre (3 foot, four inches) tall, is designed to be able to cover difficult
terrain -- such as going up steep steps -- that regular robots struggle with.
The
robot's triple-jointed legs are designed to give it maximum flexibility, with
engineers saying it will be able to go into spaces where high radiation makes
it impossible for workers to do so.The robot can carry a load of 20 kilograms
and is equipped with cameras and a radiation meter, expected to help workers
decide which parts of buildings are safe to enter and for how long.
The
machine can also carry a small wired vehicle equipped with a camera and send it
out to crawl into small spaces to carry out inspections. Toshiba engineer Goro
Yanase said the as-yet unnamed robot could be upgraded to carry more than 80
kilograms, climb ladders and step over obstacles up to 50 centimetres (20
inches) high.
Robots
have already been used inside the wrecked plant to take video footage,
including the US-made PackBot and Japanese-made Quince crawler robots, but
Toshiba is awaiting the go ahead from plant operator TEPCO to deploy its
creation. The massive earthquake and tsunami of March 11 last year sparked an
atomic emergency at the Fukushima Daiichi plant in the northeast of the
country.
Efforts
to clear up after the worst nuclear disaster since Chernobyl in 1986 are still
continuing, with high levels of radiation hampering operations. The
decommissioning of the crippled plant is expected to take several decades.
