This paper proposes a new mass measurement method in microgravity environment. System consists of a prismatic variable stiffness mechanism, and an actuator. An object is attached at the tip of the prismatic variable stiffness mechanism that can adjust the stiffness to the external force that acts on the rectilinear. The actuator oscillates the mechanism with a desired period, and the stiffness of the mechanism is controlled to satisfy the anti-resonance mode. The mass of the object is measured with the desired period of the oscillation and the stiffness in the anti-resonance mode. This method does not require any geometric parameters of the object so that mass can be measured without depending on its shape. Some experiments are executed to confirm the effectiveness of the proposed method.
