This product uses wind energy or electric energy to drive the gear set to change speed to drive the center of the crankshaft to rotate. The crankshaft is composed of three sets of 120-degree symmetrically distributed connecting rod necks. The connecting rods are used to make the rotary motion into a reciprocating linear motion. Make the robot walk reasonably. Understand the principle of mechanical transmission and the significance of rational use of wind energy through experiments.
