Motion planning is a fundamental problem in a number of application areas, including robotics, automation, and virtual reality. This paper describes a parallel implementation of a motion planning algorithm particularly suited for complex systems characterized by many degrees of freedom. The implementation is based on the concurrent exploration of the search(More)
— The Programming by Demonstration paradigm promises to reduce the complexity incurred in programming robot tasks. Its aim is to let robot systems learn new behaviors from a human operator demonstration. In this paper, we argue that while providing demonstrations in the real environment enables teaching of general tasks, for tasks whose essential features(More)
Due to the high number of sensors managed and need to perform complex reasoning activities, real-time control systems of autonomous robots exhibit a high potential for overload, i.e., real-time tasks missing their deadlines. In these systems overload should be regarded as a likely occurrence and hence managed accordingly. In this paper we illustrate a novel(More)
— The next generation of tools for rehabilitation robotics requires advanced human-robot interfaces able to activate the device as soon as patient's motion intention is raised. This paper investigated the suitability of Support Vector Machine (SVM) classifiers for identification of locomotion intentions from surface electromyography (sEMG) data. A(More)
Probabilistic path planning driven by a potential field is a well established technique and has been successfully exploited to solve complex problems arising in a variety of domains. However, planners implementing this approach are rather inefficient in dealing with certain types of local minima occurring in the potential field, especially those(More)
In recent years, several technical architectural paradigms have been proposed to support the development of distributed and concurrent systems. Object-oriented, component-based, service-oriented approaches are among the most recent paradigms for the implementation of heterogeneous software products that require complex interprocess communications and event(More)
The increasing use of System Area Network (SAN) demands efficient communication to benefit of SAN features through a direct access to network resources and avoiding kernel intervention in communication path. Recently, a consortium composed by Microsoft, Compaq and Intel authored a new standard, the Virtual Interface Architecture (VIA), designed to reduce(More)
