Tokyo Electric Power Co. (TEPCO) released new video, where robots are being deployed at the Fukushima Daiichi nuclear power plant in order to measure radiation levels and other conditions after the recent earthquake in Japan.
It is the first time in over a month that officials have been able to inspect the damage to Units 1 and 3 at Fukushima, as radiation levels there are still too high for workers to enter, reports said.
Hidehiko Nishiyama of Japan's Nuclear and Industrial Safety Agency said that the robots had taken readings for temperature, pressure and radioactivity, but radioactivity inside must be reduced before workers are allowed back inside.
Packbots, made by US robotics company iRobot Corp, have been sent into the damaged nuclear power plant to measure radiation, oxygen and temperature levels within the reactor.
Each Packbot weighs 10.9 kg. They are equipped with a three-link arm that can lift 13.6 kilograms in order to move debris and reposition harmful materials.
