FIG. 7 is a plan view of FIG. 4.

Claims

[Scope of utility model registration request]

(1) A simulated hand having a shape resembling a human hand, where at least in relation to the knuckles, there is an apparent difference between a temperature higher than the transformation temperature of thermoelastic martensitic transformation and a temperature lower than the transformation temperature. A shape memory alloy member that expands, contracts or bends is provided, and by changing the amount of current applied to the shape memory alloy member, the amount of bending and stretching of the finger joint is controlled, and the finger changes into a desired shape. Features simulated hands.

(2) In relation to the finger joint, an elastic member such as a spring is further provided, and the spring is configured to cause the shape memory alloy member to react when the temperature of the shape memory alloy member becomes lower than the transformation temperature due to stopping of electricity supply. The simulated hand according to claim 1, which is a registered utility model, is characterized in that the simulated hand works to assist in changing the shape when it is formed into a desired shape at a low temperature.

(3) The simulated hand according to claim 1 or 2 of the claims registered as a utility model, wherein the shape memory alloy member is electrically connected so that it can be controlled on a finger-by-finger basis. .

(4) The shape memory alloy members provided at least in the finger joints are electrically connected in series for each finger, and the shape memory alloy members provided in the index finger and middle finger are arranged as a first series. Shape memory alloy members provided on the thumb, ring finger, and little finger are electrically connected in series as a second series, and energization to the first and second series is controlled respectively. It is characterized by being able to change the shape depending on the point to represent rock-paper-scissors movements of goo, scissors, and par.
The simulated hand according to claim 1 or 2 of the utility model registration claim.
