ROBOTIC HAND USING TORSIONAL SHAPE-MEMORY-ALLOY ACTUATORS

摘要

The present invention is characterized in that a wire of a shape memory alloy material whose both ends are connected to the respective rotating bodies while being wound in opposite directions to a rotating shaft which hinges the two rotating bodies is shrunk due to an increase in external temperature, The present invention relates to a robot hand using a shape memory alloy rotary actuator that exhibits motion characteristics similar to those of a human hand joint by applying an actuator that generates bidirectional power to the rotary body using a memory effect for each joint.
