TECHNOLOGY REVIEW: When an earthquake and tsunami devastated Japan’s Fukushima Daiichi nuclear power plant in 2011, causing a catastrophic meltdown and radiation leak, plans to use robots to perform much-needed repairs were quickly dashed. The environment simply proved too complex and unstable for any normal robot to venture into.
The Japan Times now reports that Toshiba, which manufactured the worst-hit reactor and is helping with the cleanup, has made a two-armed submersible robot that will float into reactor 3 to try to remove debris and retrieve some of the reactor’s fuel rods. The effort shows that, in contrast to all the fancy robots tested at the DARPA challenge, a simple, custom-made machine is sometimes the best solution for a given task.
