In this paper, we introduce new performance indices to characterize the workspace of reconfigurable hyper-redundant robotic arms. These indices are then used to analyze the workspace of a type of hyper-redundant robotic arm using as modules lower mobility parallel platforms. The modules of the reconfigurable robotic arm are the three-legged translational universal–prismatic–universal (UPU) and ...

Relatively few studies have been reported that document how proprioception varies across the workspace of the human arm. Here we examined proprioceptive function across a horizontal planar workspace, using a new method that avoids active movement and interactions with other sensory modalities. We systematically mapped both proprioceptive acuity (sensitivity to hand position change) and bias (pe...

This work addresses the problem arising on all construction sites: the occurrence of workspace interference between construction activities. From a site space planning context, this problem can lead to an inevitable roadblock to the progress of the scheduled construction operations. In real situations, when the spatial congestions occur, they could reduce productivity of workers sharing the sam...

In the last few years, automatic guidance of agricultural vehicles has received increased interest to improve field efficiency, while releasing human workers from monotonous operations. this context, work proposes a short or medium-term alternative complete automation manual harvesting processes by introducing fleet robotic N-trailer support crop transportation task. With aim coordinate several...

We examined the generalization of adjustment to a visuomotor rotation across the workspace in younger and older adults. Participants practiced in the right workspace with a single target direction and were tested in both the right and left workspace with eight different target directions. A set of tests served to identify implicit and explicit components of adjustment. Explicit, but not implici...

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...
