This paper presents recent research progress in the manufacturing of MEMS based robotic positioning technology. The goal is to configure a nanofactory consisting of multiple microrobots that combine high precision with high throughput along with other application-specific requirements such as strength, dexterity, and work volume. This requires design to satisfy part mobility and dexterous manipulation with high precision. The first microrobot called the Articulated Four Axes Microrobot (AFAM) is a 3D dexterous micromanipulator robot, and we describe nano indentation experiments using AFM tips mounted on the microrobot. By combining positioning data obtained using laser interferometers and SEM imaging of nano indentation data, precision metrics such as accuracy, repeatability and resolution of the AFAM robot are determined. Preliminary reliability findings are presented. The second robot type is the ARRIpede microcrawler, and we present recent progress in microrobot precision evaluation including motion resolution and repeatability. Using these two microrobots as basic positioning and manipulation units, a nanoassembly module concept for hybrid nano assembly applications is proposed. In this paper we present recent progress in fabricating, assembling and evaluating the basic microfactory modules.

Basic physical properties of solutions with high precision are highly needed. The conventional devices can’t meet this demand. However, the magnetic suspension balance (MSB) could solve this problem. This paper summarizes the applications of MSB on the basic physical properties such as density, solubility, diffusion coefficient, adsorption, mass transfer, interfacial tension, specific volume, and so on. There is also a brief introduction about the measurement on fluid viscosity by the MSB after renovation.

A narrow-linewidth laser with excellent temporal coherence is an important light source for microphysics, space detection, and high-precision measurement. An ultranarrow-linewidth output with a linewidth as narrow as subhertz has been generated with a theoretical coherence length over millions of kilometers. Traditional grating spectrum measurement technology has a wide wavelength scanning range and an extended dynamic range, but the spectral resolution can only reach the gigahertz level. The spectral resolution of a high-precision Fabry–Pérot interferometer can only reach the megahertz level. With the continuous improvement of laser coherence, the requirements for laser linewidth measurement technology are increasing, which also promotes the rapid development of narrow-linewidth lasers and their applications. In this article, narrow-linewidth measurement methods and their research progress are reviewed to provide a reference for researchers engaged in the development, measurement, and applications of narrow-linewidth lasers.
