BIO-MIMETIC MOMENT DIRECTION SWITCHING LATCH AND SMALL JUMPING ROBOT LEGS USING THE SAME, CAPABLE OF CAUSING A ROBOT TO JUMP BY INSTANTANEOUSLY ROTATING LEGS OF THE ROBOT WITH A STRONG DRIVING FORCE
BIO-MIMETIC MOMENT DIRECTION SWITCHING LATCH AND SMALL JUMPING ROBOT LEGS USING THE SAME, CAPABLE OF CAUSING A ROBOT TO JUMP BY INSTANTANEOUSLY ROTATING LEGS OF THE ROBOT WITH A STRONG DRIVING FORCE
PURPOSE: A bio-mimetic moment direction switching latch and small jumping robot legs using the same are provided to rapidly rotates legs with a strong propulsion force by supplying a strong force to the legs at an initial stage of an operation because the action direction of a moment is instantaneously changed.;CONSTITUTION: A bio-mimetic moment direction switching latch comprises legs(10), an extension elastic element(20), and a trigger(30). The legs are joined to be rotated around a rotary center(15). The upper part of the extension elastic element is connected to a setting portion of a body and extended to one side of a rotational center and the lower part of the extension elastic element is joined to the leg in a first position under the rotational center. The extension elastic element supplies a pulling force in a direction to hold the leg at the first position. The trigger moves the extension elastic element toward the other side over the rotational center in a state where the pulling force is supplied so that an action direction of a rotational moment generated by a force actuating on the legs is changed and the legs rotate toward a second position.;COPYRIGHT KIPO 2012
