Water Strider Robot is a kind of bio-inspired micro robot that can stand and move on water surface via surface tension as insect water strider. Therefore WSR can save greatly energy because avoid from the water viscous drag, that is the main resistance to hinder the boat, submarine and fish-like robot. This makes it has the features of tiny drag, high speed, great agile, capability of accessing to shallow water and small disturbance to the water. As a new come important research area, WSR is currently developing in few universities of USA, Japan and China. In this paper, the state of the arts of theory, technology and system development about the water strider robot is mainly introduced. Then, a series of developing strategies for a novel WSR is proposed and discussed.
