In this paper, we develop a robotic table tennis system in the case of the back spin with the same measurement method and the ball models of the aerodynamics and the rebounds as in the study of Nakashima et al. (2011). First, the aerodynamics model is improved for precise prediction of the ball trajectory with data of the flying back-spin ball. Second, a method to determine the racket motion is...

We have developed a cognitive architecture for a robotic teammate based on the neuro-psychological principles of perceptual symbols and simulation, with the aim of attaining increased fluency in human-robot teams. An instantiation of this architecture was implemented on a robotic desk lamp, performing in a human-robot collaborative task. This paper describes initial results from a human-subject...

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau...

Tracing leaks of airborne radio-active, poisonous or flammable materials is a potentially dangerous activity that could be undertaken by robotic systems. This paper describes a practical investigation of the possibility of developing simple, low cost, autonomous robots to perform this task. It is envisaged that these robots would be used in large numbers. This would improve reliability through ...

We present a zipper-based instruction set for constructing genetic programming variation operators. We study the effects of such variation operators on the lawnmower problem. Operators in this language possess the ability to outperform standard mutation and crossover in terms of both decreasing the average population error as well as the best population error. Furthermore, the expression of sta...

Understanding and designing appropriate educational youth safety programs for the Amish requires an appreciation of their history, their distinctiveness in an American society built on economic, social and cultural change, and how the Amish themselves have changed over the years. The qualitative research study highlighted in this paper sought to determine culturally and age-appropriate curricul...

Robotic search and rescue is a challenging yet promising research area which has significant real-world application potentials. In this paper, a survey of multi-robot systems and how they can be implemented in search and rescue operations is presented. In particular, the problems of task allocation, communication, and human-robot interaction in multi-robot systems are explored.

Robotic lawnmowers currently available in the market cover their assigned area using a random reflection navigation strategy. While this strategy has been widely accepted for autonomous vacuum cleaning systems, it poses quality problems in outdoor applications since a randomic crossing of the garden can lead to an uneven mowing. In this paper we propose a localization algorithm based on a modif...
