Abstract: The present invention relates to a manual brake apparatus for a cable driving apparatus, which can brake the movement of a cable by being connected to a cable driving apparatus which can move the cable bilaterally. The manual brake apparatus for a cable driving apparatus comprises a cable which moves back and forth depending on the operation of the cable driving apparatus; a one-way clutch which is formed to rotate only in one direction to a fixed shaft; and a capstan which is installed on the one-way clutch by being wound with the cable. The capstan rotates in the moving direction of the cable when the cable moves toward the cable driving apparatus by the cable driving apparatus; the capstan stops by braking the movement of the cable with the one-way clutch and friction force which is generated between the capstan and the cable when the cable stops.

Abstract: 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.

Abstract: PURPOSE: A shape memory alloy double spring and a shape memory alloy actuator having the same are provided to secure high output of a shape memory alloy actuator because the deformation amount per unit length of a shape memory alloy double spring is greater than that of the conventional spring. CONSTITUTION: A shape memory alloy actuator comprises a shape memory alloy double spring(10), a power unit, and an output unit. The shape memory alloy double spring has a double spring structure in which a primary spring formed by spirally coiling a wire is spirally coiled again. The power unit thermal elastically transforms the shape memory alloy double spring by applying power to the shape memory alloy double spring. The output unit is connected to an end of the shape memory alloy double spring and outputs the deformation amount of the shape memory alloy double spring in a desired exercise form.
