Abstract
The agility of enterprises is analyzed in this article from two perspectives: business and organizational agility, and operational and logistics agility. Because of the powerful support of information technologies, mainly AI and networking, companies can seek collaborators to accomplish complex customers’ requirements without investing to expand their own capacity. The emerging alliances of enterprises are virtually formed for various customers’ and markets’ needs. This concept sustains business and organizational agility. In terms of operational and logistics agility, this article suggests that the connection between the autonomy functions and agility requires further study. Our research has proposed that error detection and recovery, and conflict resolution are two significant functions of operational and logistics agility, and determine the expected benefits from the business and organizational agility. The link between a given enterprise flexibility and agility is also analyzed.

Abstract
The abilities and limitations of today's industrial robots are reviewed and compared to similar human parameters. The robot abilities were determined from a survey of 282 current robot models. This discussion is held within the general framework of a skills analysis approach to robot task performance.

Abstract
National Engineers' Week takes place annually during the week of George Washington's birthday. Washington, best known as a soldier and stateman, was also a surveyor and road builder. The National Society of Professional Engineers began this tradition in 1950 with a two‐page article in The American Engineer. The society promoted Engineers Week on a national level beginning in 1951. February and March issues of The American Engineer in 1951 discussed the early celebrations of this week. The society's history (Robbins) also gives insights about the creation of this special week. Although the National Society of Professional Engineers initiated this week, other engineering organizations became involved later. At the present time, many organizations participate in the celebration. Each year, the National Society of Professional Engineers plans a particular theme for the week.

Abstract
One of the first steps in designing a flexible assembly system is the selection of an appropriate manipulator. There are a number of different manipulator configurations which can be chosen depending on a variety of factors such as the assembly workspace layout, product size, weight, and component insertion direction.A number of methodologies have been written to help the selection of a manipulator for process cells. However, little work exists to aid the machine designer in the selection of an appropriate manipulator for flexible assembly. This paper examines the factors which affect this process.

Abstract
This paper presents our development of a novel Internet‐based E‐manufacturing system to advance applications in micromanipulation and microassembly using an in situ polyvinylidene fluoride (PVDF) piezoelectric sensor. In this system, to allow close monitoring of magnitude and direction of microforces (adhesion, surface tension, friction, and assembly forces) acting on microdevices during assembly, the PVDF polymer films are used to fabricate the highly sensitive 1D and 2D sensors, which can detect the real‐time microforce and force rate information during assembly processes. This technology has been successfully used to perform a tele‐assembly of the surface MEMS structures with force/visual feedback via Internet between USA and Hong Kong. Ultimately, this E‐manufacture system will provide a critical and major step towards the development of automated micromanufacturing processes for batch assembly of microdevices.

Abstract
This paper presents our development of a novel force and force rate sensory system to advance applications in micromanipulation using an in situ polyvinylidene fluoride (PVDF) piezoelectric sensor. To allow close monitoring of magnitude and direction of microforces acting on microdevices during manipulation, PVDF ploymer films are used to fabricate highly sensitive 1D and 2D sensors to detect real‐time microforce and force rate information during the manipulation process. The sensory system with a resolution in the range of sub‐micronewtons can be applied effectively to develop a technology on the force‐reflection microassembly of surface MEMS structures. In addition, a tele‐micromanipulation platform, which can be used to perform tele‐microassembly of the MEMS structures and tele‐cell‐manipulation with force/haptic feedback via Internet was also built successfully.
