  • Patent number: 10724507
    Abstract: The present invention provides an active clutch mechanism and a hopping robot equipped with the same, the active clutch mechanism comprising: a sun gear; a planetary gear; and a winding gear. When the sun gear rotates in one direction, the planetary gear revolves around the sun gear in the one direction to come into contact with the winding gear, and then rotates the winding gear to wind a wire so as to store energy in an energy storage unit connected to the winding gear. When the sun gear rotates in a direction opposite to the one direction, the planetary gear revolves around the sun gear in the direction different from the one direction to become spaced from the winding gear, so as to discharge the energy stored in the energy storage unit.
