Probabilistic roadmap planners have been very successful in path planning for a wide variety of problems, especially applications involving robots with many degrees of freedom. These planners randomly sample the configuration space, building up a roadmap that connects the samples. A major problem is finding valid configurations in tight areas, and many methods have been proposed to more effecti...

Web-based collaboration is becoming increasingly common. Often such collaboration exhibits emergent characteristics, for which systems based on a notion of workspaces provide suitable support. Virtual teams collaborating in this manner create virtual organizational structures, the capture and retention of which into organizational memory promises to be of benefit, as it can facilitate reuse. Vi...

The Problem: To build workspaces that effectively support people in everyday work situations, one needs to focus on both the technology and the physical environment in which work takes place. Much progress has been made in recent years in developing technology: Research in intelligent spaces—those spaces in which technology has been embedded in support of people’s tasks—has focused on such issu...

A systematic study is performed for the workspace characteristics and orientation capability analysis of 3R planar manipulators. This study will aid the design and control of this kind of manipulators. This particular manipulator is well suited for industrial applications in aided automation manufacturing as well as medical applications for orthopaedic surgery robotics and micro holder for tact...

This paper describes the VITE system, a spatial hypertext system that supports two-way mapping for projecting structured information to a two-dimensional workspace and updating the structured information based on user interactions in the workspace. VITE uses information visualization techniques to render structured information in the workspace and provides users an environment to interact with ...

This paper presents a new method to calculate and display an approximated workspace of a surgical robot in nearly realtime. Displaying this information on a screen in the operation room could support the surgeon during intraoperative trocar placement for teleoperated minimally invasive robotic surgery (MIRS). We give a short overview on existing trocar placement procedures in teleoperated MIRS ...
