SHAPE MEMORY MATERIAL TORSION GENERATION ACTUATOR, ARTICULATED JOINT OF LINKS AND LINKS DEVICE HAVING THE SAME

摘要

The present invention is installed on the link joints two links rotatably formed relative to the adjacent one another , and , depending on the temperature changes in the current supply wires of the shape memory material is deformed , and the length of each wound to both ends of the torsion springs connected to each of the two links heongtae , a spring coil axis of rotation axis of the joint part between the both ends of action the rotation axis direction of the coil spring by the rotational transformation of a shape memory material that can provide the rotational force of the two link actuators generate torsion in accordance with the change in length , is described for the joint link and the link mechanism having the same structure . ;
