| Outline of Final Research Achievements |
In first year, improvement of robot boat technology and development of the drone type float with GPS receiver were conducted. The basic principle is the same as that of a standard floating method. The trajectory of the float and the traveling velocity could be evaluated by using the time-series of the position coordinates of the GPS. A sonar could measure the water depth and cross-sectional area of a river.
In second year onward, installing the GPS receiver and the sonar in the robot boat, an autonomous robot float could be developed. This can measure comparatively fast flow and detect the flow direction. Furthermore, a flume measurement in the laboratory was performed to consider effects of wind on the discharge evaluation.
