Striving for greater accuracy and greater performance, some machine manufactures are developing parallel structure for the next generation machine. This necessarties that these machines need to be analyzed for the effects of existing singularities inside or boundary of evaluated workspace of indigenously developed 6-DoF SPS (S: Spherical, P: Prismatic) parallel manipulator here in Bhabha atomic...

A microrobotic leg actuated with amplifying mechanisms is developed in this letter to mimic the motion of legs natural organisms on small scale. The device has a planar structure and fabricated bulk micromachining. Two electrothermal actuators are used drive back forth workspace. actuator transmitted elastically using flexible arms. mechanism symmetrical similar standard parallel manipulators b...

For workspace-to-workspace awareness systems, the design of the underlying infrastructure stands out as difficult. We discuss our experience building infrastructures and visualizations that aim to help people better coordinate their work, showing how our infrastructures have evolved through four of our prototype systems: Palant́ır, Lighthouse, Workspace Activity Viewer, and World View. Through o...

WEA is our implementation of a new architectural model for virtual memory access, the WorkSpace. It relies on a generalisation of client / server model and enables to build new distributed applications. The workspace supplies uniform access to a distributed persistent object store. This paper describes several ways of building multi-workspace architecture, and an implementation of this architec...

UNLABELLED The article examines which subjectively evaluated indoor environmental parameters and building features mostly affect occupants' satisfaction in mainly US office buildings. The study analyzed data from a web-based survey administered to 52,980 occupants in 351 office buildings over 10 years by the Center for the Built Environment. The survey uses 7-point ordered scale questions perta...

We present a perception system, called Artisan, that semi-automatically builds 3-D models of a robot’s workspace. Range images are acquired with a scanning laser rangefinder and then processed, based on a systematic sensor characterization, to remove noise and artifacts. Complex 3-D objects represented as surface meshes are subsequently recognized in the range images and inserted into a virtual...

this paper presents the kinematic analysis and the development of a 4-degree-of-freedom serial-parallel mechanism for large commercial vehicle driving simulators. the degrees of freedom are selected according to the target maneuvers and the structure of human motion perception organs. several kinematic properties of parallel part of the mechanism under study are investigated, including the inve...
