Robots venture inside Fukushima

UK defence technology firm QinetiQ has supplied a range of remote controlled machines that will enable engineers to look around inside the Fukushima nuclear plant.

The Talon robot is known as a "radiation first responder". Its main job will be to move through rubble inside the plant and send back radiation readings. Talon was previously used at the World Trade Centre site in New York City to monitor hazardous chemicals.

Japanese teams receive instruction in using the remote controlled robots. "I am so impressed with the spirit of the Japanese people as they tackle this difficult recovery effort," said QinetiQ's JD Crouch.

The Talon robots are operated from a ruggedized control system. Operators are able to view the output from Talon's cameras. In addition to visible light, engineers can also opt for an infra-red view.

These may look like ordinary "Bobcat" diggers, but modifications to their control systems allow them to be operated remotely. Different attachments allow the machines to dig, lift, cut and break through walls and doors.

If the Bobcat's controller looks familiar that is because it is taken from an XBox 360 games console.

iRobot's Packbot machines have already been operating inside the Fukushima nuclear plant. Like the Talon, Packbot is able to take atmospheric samples, including radiation levels.

Packbot is able to carry out delicate operations, such as adjusting equipment inside the plant. The technology has been used extensively in war zones for a range of tasks, including bomb disposal
