Adaptive optics is being used for high-quality limiting features of optical tools, aperture synthesis, automated image processing tools, and the building of extraordinarily large optical telescopes, among other things, in current astronomy. On Earth and in space, the proposed adjustment mechanism can be employed in optical equipment (for adaptive optics, laser mirror adjustment, customising fiber-optic systems, and so on). In automated optical-mechanical systems, using a high-precision drive helps correct picture distortion caused by several types of agitation - vibratile, thermic, and electromagnetic - in real time. Improved positioning accuracy in automatic mode, reduced transient process duration, active shock absorption, adjustment and stabilisation of object position, increased number of degrees of freedom during positioning and vibration isolation, self-braking hydraulic cylinders, and smaller overall dimensions are all features of the adjustment and vibration isolation system. A multimotion actuator based on magnetorheological (MR) fluid that was hermetically encased by metal bellows was used to achieve these goals. Because of the all-metal hermetic bellows, the adjustment system can be operated in ultrahigh vacuum, including open space. The design, operating idea, dynamic performance of the MR drive, and transient process parameters during step-by-step positioning are all described in this study. The electromagnetic system of the MR drive has been calculated and the results have been provided.
