A Micro Bionic Flapping Wing Robot on Water Surface

Sliding and jumping are the two main motion modes of micro water sports robots, flying motion can further expand the range of motion in near-water space and improve the maneuverability and flexibility of robots, it has become an inevitable trend in the development of micro-robots. Surface flying involves two media, water and air. Limited by the complexity of water supporting force and lift resistance, it is difficult for a robot to take off on the water surface. In this paper, a micro flapping wing flying robot that can take off on the water surface is developed by combining the floating principle of water strider and the flying motion of hummingbirds. The weight and wingspan of the robot are 13 g and 21 cm respectively, and the flapping amplitude is 180°. The water surface flying experiments verifies that the flying height is 25 cm, the take-off response time is 0.1 s, and the average vertical take-off speed is 1 m/s.
