Resumen de Deep inside Fukushima
In the dark abandoned shell of Fukushima Daiichi nuclear power plant, Rosemary and Sakura shoot what looks like a dystopian first-person shooter game. Rosemary scans her environment, while Sakura records every move. Developed at the Chiba Institute of Technology, Rosemary and Sakura can climb 45 degree slopes and use gyroscopes and other sensors to navigate inside buildings without the need for GPS. But the standard radiation detector, gamma cameras weighing 150 kilograms, proved too cumbersome for them to use. So the team has turned to a gamma camera that weighs just 17 kilograms and can rotate 360 degrees. This has been added to the robots as part of a system called N-Visage, which also includes a laser scanner that draws a 3D image of its environment. The radiation measurements can be combined with a laser scan of the plant's exact layout, says Trevor Craig of UK start-up Createc, which developed N-Visage for Japan's International Research Institute for Nuclear Decommissioning, and reactor maker Hitachi. An earlier version was used in Sellafield in Cumbria
