Abstract

The invention discloses a rollover movement control method of a multi-joint dolphin robot. A control method and achieving steps of front rollover movements and rear rollover movements of the dolphin robot are provided by performing theoretical analysis and system research on the front rollover movements and the rear rollover movements of the dolphin robot and combining a propulsion mechanism of movements of a dolphin. Due to the fact that the front rollover movements and the rear rollover movements of the dolphin robot belong to pitching movements of the dolphin, first the pitching movements of the dolphin are analyzed and divided into a bending stage and an stretching stage, the bending stage and the stretching stage are respectively analyzed, a calculation formula of a joint turning angle and a movement path of joints during the pitching movements are provided, and movements of pitching joints of the dolphin robot are controlled. The rollover movement control method of the multi-joint dolphin robot can accurately control a pitch angle of the dolphin robot during the movements, and achieves accuracy of pitching movement control of the dolphin robot.

Description

technical field [0001] The invention relates to the field of bionics, in particular to a method for controlling the rolling motion of a multi-joint robot dolphin. Background technique [0002] Dolphins, as marine mammals, possess amazing swimming techniques and drag-reducing abilities. When dolphins swim, relying on the up and down swing of the tail peduncle and tail fin and the cooperation of the pectoral fins, the instantaneous swimming speed can reach as high as 11m / s. When a dolphin changes its speed and direction, its skin will wrinkle to suppress the turbulent flow, thereby greatly reducing the resistance of the water and making the average propulsion efficiency of the dolphin between 0.75 and 0.90. In addition, the dolphin has super steering maneuverability and flexibility, its steering angle can reach 561.6° / s, and the turning radius can even be less than 0.2 body length. In view of the good mobility, flexibility and efficiency of dolphins, it has good application ...
