workspace analysis is one of the most important issues in the robotic parallel manipulator design. ‎however, ‎the unidirectional constraint imposed by cables causes this analysis more challenging in the cabledriven redundant parallel manipulators. controllable workspace is one of the general workspace in the cabledriven redundant parallel manipulators due to the dependency on geometry parameter...

Striving for greater accuracy, some machine tool manufacturers are developing parallel structures for the next generation machine tool. Therefore, tools are needed to analyze the effect error sources have on this type of structure. A model of a Stewart Platform based machine tool is developed that provides the framework for inclusion of all relevant error sources. An error analysis is presented...

Human performance measures such as discomfort and joint displacement play an important role in product design. The virtual human Santos, a new generation of virtual humans developed at the University of Iowa, goes directly to the computer-aided design model to evaluate a design, saving time and money. This paper presents an optimization-based workspace zone differentiation and visualization. Ar...

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...

We describe the implementation of a system which enables a user to interact with and modify an electronic holographic image using a force-feedback device. The force-feedback (or haptic) device is capable of sensing and reporting the 3D position of its hand-held stylus and displaying appropriate forces to the user. Thus, a user can feel and modify algorithmically specified shapes in the haptic w...

Next-generation Grid applications will operate within and across many heterogeneous network types, will employ a wide range of device types ranging from supercomputers to sensor motes; and will require many more “interaction paradigms” than merely RPC and message-passing. The Open Overlays project proposes a middleware approach to satisfy these emerging needs. In this paper we describe an appli...

The problem of e ciently moving a pair of omni directional robots carrying a ladder using distributed control is discussed We rst consider the case in which two robots that may di er only in their maximum speeds are situated in an obstacle free workspace and present two distributed algorithms Next a distributed algorithm is presented for the case in which the workspace is a narrow corridor with...

Abstract—In this paper, we propose an office layout support system using genetic algorithm. The proposed system has two phases; (1) generation of room arrangement plans and (2) generation of layout plans for workspace. In the proposed system, some conditions on rooms and furniture are given by a user, some room arrangement plans which satisfy the conditions are generated by genetic algorithm. A...
