Abstract

A pull cord type turning mechanism for a butterfly-inspired flapping-wing aerial robot includes a motor, a cord reel, a cord reel gear, a potentiometer gear, a potentiometer, a control module, and a power supply. The control module is connected to the motor and the potentiometer. A rotary shaft of the motor is connected to the cord reel, the cord reel is coaxially connected to the cord reel gear, the cord reel gear is meshed with the potentiometer gear, and the potentiometer gear is connected to a rotary shaft of the potentiometer. The cord reel gear is provided with two cord grooves and two pull cords. One ends of the two pull cords are fixed in the two cord grooves, respectively, and the other ends thereof are fixed at the tips of front wings of two sides of the butterfly-inspired flapping-wing aerial robot, respectively.
