This study proposes an algorithm for automatic generating motion trajectories of robot manipulator. This algorithm consists of two procedures. First, motion trajectories of the tool head are generated by using the concept of repulsive vector fields and motion trajectories model which consists of a number of spr ings and mass. Then, a posture of robot manipulator is also automatically generated using the same concept. We are planning to apply this system as a remote handling device for nuclear power plants....

Algorithm for Automatic Generating Motion Trajectories of Robot Manipulator in Nuclear Power Plant

Due to the increase in aging social infrastructures and the shortage of human resources with the declining birthrate and aging society, labor saving in patrol and inspection work is required. The purpose of this work is not only to reduce the load of patrol and inspection but also to provide new services such as digitization of inspection data. We have developed autonomous four-wheel robot and drone as mobile platforms that can patrol on behalf of workers. The robot can take pictures of the target equipment...

This paper describes development of the remotely operated device for vacuum cleaning and visual inspection in boiling water reactors to enhance the availability of operating nuclear power plants. Fuel damage can occur if loose debris inside t he reactor vessel flows through the fuel and it can become a serious issue affecting plant reliability and radiation levels, therefore, removing the small debris on the bottom head is significant activities in nuclear power plants. While it i s difficult to remove sma...
