Many existing actuators have problems such as high rigidity and low impact resistance. The "Elastic Short Motor", in which the rotor and stator of the motor are connected by an elastic body, has the simplicity of mainly consisting of two parts, but shows various pattern deformations depending on the shape and the connecting direction of the elastic body. The "Elastic Short Motor" can generate an instantaneous force by snap-through buckling, and the impulse is estimated to be 3.05∙10^(-2) [kg∙m/s]. Although this value is smaller than other instantaneous force generation mechanisms, it also has properties such as energy conservation like the Series-Elastic Actuator.
