Here is a robot designed to collect debris at a damaged Fukushima Reactor in Japan. Jacobs’ robotic tool is made to collect debris that is at the bottom of the reactor containment vessel. Samples will be used to figure out the next steps in the clean-up and decommissioning of the Fukushima reactors. As the company explains:
the robotic tool had to meet more than 300 functional, operational, performance and geometric requirements. It also had to be small enough to enter the damaged containment vessel and pick up sand and pebbles up to 10 millimeters in size by deploying a bucket-style retrieval device.
Trials have shown that a remote operator needs about 8 minutes to insert the device into the vessel and retrieve samples. More information is available here.
