Overview of flexure-based compliant microgrippers
Aia, Wenji,Xu, Qingsong Techno-Press 2014 Advances in robotics research Vol.1 No.1
Microgripper is an essential device in the micro-operation system. It can convert other types of energy into mechanical energy and produce clamp movement with required chucking force, which enables it a broad application prospect in the domain of tiny components' processing and assembly, biomedicine and optics, etc. The performance of a microgripper is dependent on its power supply, type of drive, mechanism structure, sensing components, and controller. This paper presents a state-of-the-art survey of recent development on flexure-based microgrippers. According to the drive type, the existing microgrippers can be mainly classified as electrostatic microgripper, electrothermal microgripper, electromagnetic microgripper, piezoelectric microgripper, and shape memory alloy microgripper. Additionally, some different mechanisms, sensors, and control methods that are used in microgripper system are reviewed. The key issue of how to choose those components in microgripper system design is also addressed.

China's rapid growth has created great opportunities for design and construction of projects that not only transform sites but cities. This work combines local, national, and international expertise in developing memorable designs that seek to humanize urban life and emphasize the importance of visionary clients. Innovative examples of work in China will be presented with emphasis on three iconic projects designed and built for Poly Corporation based in China. These projects include developments in Beijing and Guangzhou and introduce the use of locally supplied materials and construction techniques. The Poly Corporate Headquarters, the Poly Real Estate Headquarters, and the Poly International Plaza, and will be described through innovative ideas that integrate urban planning, structure, and architecture.
