In this paper we address the problem of energy optimal gait generation for biped robots Using a sim pli ed robot dynamics that ignores the e ects of cen tripetal forces we obtain unconstrained optimal tra jectories generated by piecewise constant inputs We study a complete gait cycle comprising single support double support and the transition phases The energy optimal gaits for di erent step le...

This article has focused on evaluation and identification of effective parameters in positioning performance with an odometry approach of an omni-directional mobile robot. Although there has been research in this field, but in this paper, a new approach has been proposed for mobile robot in positioning performance. With respect to experimental investigations of different parameters in omni-dire...

Nowadays, Robots account for most part of our lives in such a way that it is impossible for usto do many of affairs without them. Increasingly, the application of robots is developing fastand their functions become more sensitive and complex. One of the important requirements ofRobot use is a reliable software operation. For enhancement of reliability, it is a necessity todesign the fault toler...

industrial-scale r&d it projects depend on many sub-technologies which need to be understood and have their risks analysed before the project can begin for their success. when planning such an industrial-scale project, the list of technologies and the associations of these technologies with each other is often complex and form a network. discovery of this network of technologies is time con...

Web robots periodically crawl Web sites to download their content, thus producing potential bandwidth overload and performance degradation. To cope with their presence, it is then important to understand and predict their behavior. The analysis of the properties of the traffic generated by some commercial robots has shown that their access patterns vary: some tend to revisit the pages rather of...

(OWLS). In the Module layer, there are two kinds of module: modules for action and modules for recognition. By combining these modules, this architecture can handle symbols and signals. In this study, we applied our method to RobotCafe, which is a cafe where robots work as waiters, to enable the robots to change their greetings to suit the situation when customers come and to assist the service...

This paper describes new work and creations of LEMUR, a group of artists and technologists creating robotic musical instruments.

Controlled testing on standard tasks and within standard environments can provide meaningful performance comparisons between robots of heterogeneous design. But because they must perform practical tasks in unstructured, and therefore non-standard, environments, the benefits of this approach have barely begun to accrue for field robots. This work describes a desert trial of six student prototype...

We present a solution to prevent collisions among robots that are moving toward their respective goals. A robot may start moving at any time from its station to its goal. For a moving robot, the probability of conflict increases proportionately to the complexity of other robots’ respective routes. In terms of lowering possibilities of collision, a proper strategy for controlling robot behaviors...
