“…When compared to a typical system, they were able to achieve faster responses and larger maximum output force using the same amount of applied voltage. Besides coatings, flexure bearings [18] and mag-lev [19] technology have also facilitated friction management, helping avoid complex control algorithms. Yet, both solutions are limited, due to low stroke and load capacity in the former, and high cost and complexity in the latter [20].…”

Micro/Nano mechatronic systems might be defined as systems that include nano-or micro-scale components. These components can be sensors, actuators, and/or physical structures. Furthermore, the high-precision control laws for such small scales are important to ensure stability, accuracy, and precision in these systems. In this writing, four categories of such small-scale systems are considered by providing multifarious novel or key examples from the literature: control engineering and modeling, design and fabrication, measurement engineering, and sensor/actuator development. The applications discussed in the examples vary from nano-positioners, crucial in systems such as atomic force microscopes, to biological sensors like carbon nano-tubes that respond to chemical or molecular stimuli. It is observed that in many instances, especially in micro−/nano-robots, the categories overlap for the completion of a system that needs to be small in size, to be controllable with high accuracy, to have high precision sensing capacity, and finally to be able to carry out submillimeter measurements. Thus, a holistic point of view upon such systems is necessary for future applications. This paper does not limit the type of sensors or actuators to the industrial ones and extends the investigated examples to encompass biological sensing and actuating mechanisms that respond to chemical stimuli, proposing for the inclusion of these units in nano −/micro-mechatronic systems intended to be used in human body or other bio-environments. Several other research opportunities are discussed, challenges in the field are identified, and some propositions are put forward for future directions.

“…Lu et al investigated a new large working range parallel accuracy stage based on an optimized flexible hinge, which utilizes the stepping and continuous motion characteristics of the piezoelectric actuator to achieve high resolution and large working range positioning and adjustment [20]. Jeon et al proposed a new cylindrical magnetic levitation table, which uses a second-order statespace dynamic modeling method based on the input and output experimental data for system identification, and this table can achieve high precision translation and rotation [21]. Although the above tables achieve high positioning accuracy, they can only adjust the eccentricity of the workpiece but not the tilt.…”

The ultra-precise measurement of aero-engine rotor geometry error is the basis of its assembly, and adjusting the rotor coaxially with the measurement rotation axis is the key to ensure the measurement accuracy. As a typical adjustment device for rotor alignment, the traditional method of applying a four-degree-of-freedom centering and tilting table for adjustment does not take into account the coupling effect caused by the position of each adjustment motor not being perfectly perpendicular to each other, this paper gives the calibration method of the angle between each adjustment motor and the starting position of the angle grating, analyzes the principle of eccentricity and tilt adjustment and deduces the coupling solution method. Subsequently, the size of the coupling between the two adjustments is analyzed and an efficient adjustment method is given for its mechanical structure characteristics. The experimental results show that the platform can effectively decouple and quickly converge to the setting values of 0.3 µm and 0.5′′ for different initial eccentric distance and tilt angle. With the same adjustment accuracy, the number of adjustments is reduced by more than 50% and more than 37.5%, respectively, compared with the non-decoupled method.
