Abstract
Biological water striders have advantages such as flexible movement, low disturbance to the water surface, and low noise. Researchers have developed a large number of biomimetic water strider robots based on their movement mechanism, which have broad application prospects in water quality testing, water surface reconnaissance, and search. This article mainly reviews the research progress of biomimetic water strider robots. First, the biological and kinematic characteristics of water striders are outlined, and some mechanical parameters of biological water striders are summarized. The basic equations of water strider movement are then described. Next, an overview is given of the past and current work on skating and jumping movements of biomimetic water strider robots based on surface tension and water pressure dominance. Based on the current research status of biomimetic water strider robots, the shortcomings of current research on biomimetic water striders are summarized, and the future development of biomimetic water strider robots is discussed. This article provides new insights for the design of biomimetic water strider robots.
