Finally, some news that Japan is actually using its rescue robots. The red Wall-E-esque ‘bot seen here is on the scene at the Fukushima Daiichi nuclear plant, according to a media report from Japan.
Japan has a suite of earthquake rescue robots, but so far, there has been scant evidence of their use in this disaster. This monitoring robot, AKA Monirobo, could be the first robot confirmed to be helping humans cope with the nuclear emergency. But its role is not even clear, as a Reuters story explains.
The Japanese newspaper Asahi Shimbun (in Japanese) reports that a red Monirobo has been dispatched to the nuclear plant, on loan from the Nuclear Safety Technology Center. The red one is equipped to detect radiation levels at the crippled reactors. A yellow one, which will collect dust samples and monitor flammable gas, is expected to be deployed in the next few days.The 5-foot, 1,300-pound Monirobo has a robotic arm for collecting samples and moving obstacles, and it drives using a pair of treads. It is designed to go where humans can’t, using a radiation detector, four video cameras with 3-D capability, and temperature and humidity sensors.
Along with Monirobo, a host of other robots are mobilizing to help with recovery efforts and damage assessment. At least four teams are ready to deploy ground robots, snake robots and underwater robots, according to IEEE Spectrum. One team will inspect some underwater infrastructure in Kajima, in the Chiba Prefecture east of Tokyo, and another will go to Hachinohe, Aomori Prefecture, to check out a building with a collapsed ceiling.

Meanwhile, France — which is dependent on nuclear power for almost three-fourths of its energy — is sending radiation detectors, 2 tons of boron and its own robots to help in the cleanup and recovery efforts. It seems odd that Japan, with its robot fascination, should rely on a European nation for robot assistants.
According to Reuters, a science ministry official said a Monirobo was there, but a nuclear safety agency official said he had no reports of any robots being used.
Let’s hope it is, and that it can relieve the cadre of workers who are exposed to dangerous radiation levels inside the plant.

Don't they have a robot that can drag a hose into place at the cooling ponds/reactor cores so water can be fed in?
The electronic is going to be fried in minutes in spots whit very high radiation like inside the reactor buildings. Even when the electronic survive the radiation, the wireless could stop working. The robot must have really heavy radiation hardening to work inside a reactor (=heavy and big).
If you want to control the robot whit a wire (this means possible problems in difficult terrain), you must have a cable whit heavy hardening. This means a heavy cable. And a special protocol to offset the interferences in the connection. All in all it is difficult to use robots in such environment. But they are good in places whit higher radiation were humans can't stay for longer period.
In Chernobyl they tried to use a robot designed for work on the moon on the roof of the reactor. It died a quick electronic death.
If electronics are ruled out, a purely physical robot could be built. Hydraulic muscles for all moving parts, with the hydraulic pumps operating a long way away from the business end of the robot. Sensors aren't neven needed, as the operator could view the robot via telescopoe, also from a long way away. It would be clumsy, slow and ugly, but it would work.
"3D capability"
It can move in 3 DIMENSIONS! I thought we all lived in flat land?!
