Development of mini hydrography survey robot

This paper proposed the development of Mini Hydrography Survey Robot to operate in different flooding scenes and also working in monitoring mode. The robot displays position and the depth of the lake by drawing map in 3D topographic profiles. These will operate by a controlling system that equipped with sonar and GPS. We evaluated with performance in the practical test, it is found that the lake has 1 m. minimum and 2.4 m. maximum in depth. The results confirm that the robot could be easily run by remote control from land. The development of this invention could support and monitor the works in hydrography filed. In addition, the budget of building the robot comparing to conventional works is found that it is lower.
