    • PURPOSE: A micro rotation rate sensor and an operation method thereof are provided to require a small installation space and to obtain a very high and stable measurement accuracy in respect to an external impact and a temperature effect. CONSTITUTION: A micro rotation rate sensor includes a substrate, a plurality of masses, a plurality of anchors (2, 13), springs (4, 10), driving elements, and sensor elements. The masses can be displaced around the substrate and arranged on an X-Y plane parallel to the substrate. The anchors attach the masses onto the substrate. The springs connect some of the masses to the adjoining mass or to one or more anchors. The driving elements oscillate some of the masses to an X-direction for generating the Coriolis force when the substrate is displaced. The sensor elements senses the displacement of the masses based on the generated Coriolis force.
    • 目的:提供微转速传感器及其操作方法,以便在外部冲击和温度效应方面要求较小的安装空间并获得非常高且稳定的测量精度。 构成:微转速传感器包括基板,多个质量块,多个锚固件(2,13),弹簧(4,10),驱动元件和传感器元件。 质量可以在衬底周围移动并且布置在平行于衬底的X-Y平面上。 锚固件将质量附着到基底上。 弹簧将一些质量连接到相邻的质量块或一个或多个锚固件。 当衬底移位时,驱动元件将一些质量振荡到X方向以产生科里奥利力。 传感器元件根据生成的科里奥利力感测质量的位移。

    • An apparatus and a method for correcting bias of a gyroscope mounted on a moving robot are provided to correct the bias of the gyroscope in real time without stopping the moving robot. An apparatus for correcting bias of a gyroscope(140) mounted on a moving robot(100) includes an encoder(120), a modeling unit(130), a bias calculating unit(160), and a bias removing unit(150). The encoder measures the travel speed of wheels. The modeling unit calculates a rotating angular speed of the moving robot from the travel speed measured by the encoder. The gyroscope measures a rotating angular speed of the moving robot using the rotational inertia of mass. The bias calculating unit determines a reliable range by using the difference between the calculated rotating angular speed and the measured rotating angular speed, and calculates bias from the value falling in the reliable range from the difference. The bias removing unit removes the calculated bias from the rotating angular speed measured by the gyroscope.
