Recent studies on understanding of natural flyers have encouraged researchers in development of micro aerial vehicles mimicking birds and insects such as hummingbirds, dragonflies, bats and many more. The vehicles find their applications in reconnaissance and situational awareness in combat field, search and rescue operations, biological and nuclear compromised sites and broadcasting and sports. The focus of this review is to assess recent progress in sub systems of these vehicles including drive mechanisms, actuation mechanisms and wing designs that define the aerodynamics, propulsion, stability, and control of the vehicles. Limited research has been carried out on drive mechanisms capable of producing figure-of-eight wingtip motion contrary to conventional four and five-bar linkage mechanisms along with modified planar and spherical attachments. Motor and piezoelectric actuation mechanisms are being used extensively in these vehicles due to lightweight and power efficiency as compared to non-conventional power sources. Wing shape and rigidity plays a key role in determining the required lift and thrust along with frequency limitations and material constraints. A relatively new field of structural and kinematic optimization for the development of a lightweight flapping vehicle with high endurance capability is also a part of this review. This review has pointed out the research gaps including 3-DoF piezoelectric kinematics, under-actuated mechanisms, structural contact analysis, limited static and dynamic structural analysis, limited fatigue analysis and development of optimization techniques.

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.

“…Prior to the hydraulic valve block TO design, it is necessary to comprehensively consider the assembly relationship between the hydraulic valve block and other parts, and divide the design space and the nondesign space based on the design requirements and the structural characteristics of the hydraulic valve block. 13 The hydraulic valve block is connected with the hydraulic valve and the pipe joint through the thread, and the liquid flows in the inner channel of the valve block. Therefore, the connection area and inner hole of the valve block are defined as nondesign spaces, and the remaining part is defined as the design space (as shown in Figure 9).…”

The hydraulic valve block is a core component of an integrated hydraulic system. In practical usage, it exhibits problems such as material waste, long manufacturing cycle, significant energy loss, and leakage. Based on the aforementioned existing problems, this study presents the design of the hydraulic system valve block based on the valve block design principle. The internal valve channel of the hydraulic valve block is optimized for additive manufacturing technology to avoid auxiliary drilling, solve the problem of potential liquid leakage, and shorten the manufacturing cycle. Thus, it is more suitable for the production of customized complex hydraulic valve blocks. The multiobjective topology optimization method is applied to the lightweight design of the hydraulic valve block to save resources and decrease energy consumption. The results indicate that when compared with the original model, the minimum reduction rate of pressure loss in each oil circuit orifice after optimization of the hydraulic valve block corresponds to 32.02%, the maximum corresponds to 71.38%; the maximum stress of the final design corresponds to 542.9 MPa, which satisfies the material strength requirement; and the mass is decreased by 68.9%. Thus, the lightweight design of the hydraulic valve block is realized.
