In this paper, an underwater robot for inspecting and maintaining nuclear reactor vessel is developed. Based on the kinematics analysis of the robot, the workspace is obtained. In order to evaluate the influence of water environment to the robot, the hydrodynamic forces including water resistance and additional mass force are analyzed. Then some experiments including watertight test are performed...
There is an urgent need to check and salvage foreign objects for the nuclear power plant. A 4-DOF underwater manipulator served for nuclear power plant can complete the examination, salvage or other actions for the nuclear power station reactor core and foreign objects in the pool. In this paper, several researches on 4-DOF underwater manipulator served for nuclear power plant are carried out as follows:...
