JQR-05G/L Robot for Salvaging Underwater Foreign Bodies

The robot is most suitable for application to the nuclear power stations because it has an integrated functions including crawling underwater，video monitoring and salvaging underwater foreign bodies, and is particularly capable of salvaging underwater small foreign bodies by the combination of  underwater video vidicon with various manipulators. The robot system consists of an underwater crawling device, a video vidicon, a two-dimensional head, various manipulators, a tiny underwater suction pump/cleaning device，a controller, and a 30-m cable.
