Gesture-based interfaces have become an effective control modality within the human computer interaction realm to assist individuals with mobility impairments in accessing technologies for daily living to entertainment. Recent studies have shown that gesture-based interfaces in tandem with gaming consoles are being used to complement physical therapies at rehabilitation hospitals and in their homes...
Traditional methods of system verification call for the repeated exercise of that system in its intended environment to give confidence that it will operate as designed. Autonomous systems, however, are systems designed for sophisticated operation in stochastic environments that specifically handle the unexpected; testing all possible operational scenarios for such systems is intractably complex....
The German SpaceBot Cup is a robotics competition that has its first edition in 2013. A second edition is expected by the end of 2015. The SpaceBot application scenario involves typical exploration tasks carried out on a planetary surface after landing on a planet. Competitors' robots are challenged to locate and identify objects, and then convey them to a base station. This activity is meant to be...
Many robot planning approaches use cell decomposition methods for finding a sequence of regions that the robot should traverse. When a fully-actuated robot is used, the robot reference trajectory is simply constructed by linking through line segments the middle points of common facets of successive traversed cells. This paper improves this approach by proposing three different optimizations that yield...
This paper addresses the problem of evaluating the grasping capabilities of a robot hand. The purpose of such evaluation is to provide numerical results that enable the comparison of different aspects of robot hand designs which can lead to improve their performance. The methodology proposed in this paper consists of computing an exhaustive amount of grasp configurations for each robot hand over a...
We present an improved algorithm to RRT∗ in this paper. Our algorithm tries to increase the efficiency by replacing the Initialtree() of RRT∗ with a RRT tree only contains one solution to speed up finding a feasible solution, and then applying a RRT∗_S algorithm to optimize the current solution. This RRT∗_S is similar with RRT∗ in principle, but it does not insert extra nodes into the current tree...
As one of the most unique types of art in Chinese culture, nowadays Chinese calligraphy is attracting increasing interests from researchers. It will be a big step if we have a robot to write Chinese calligraphy, especially in various styles, and it will form a bridge to combine science with art directly. However, there are so many different types and styles in Chinese calligraphy, and to distinguish...
Putting robotic automation to work in a mid-nineties vintage 8” wafer fab is without a doubt a challenging maneuver. Therefore it is not at all surprising that any rigorous project scope puts all its momentum into getting the robots automatically moving wafers based on the existing standard workflows — in other words — executing the non exceptional everyday workflows. In the case of manufacturing...
