We model the rebound phenomenon between a ping-pong ball and the table/racket rubber. In the model between the ball and racket rubber, it is assumed that the kinetic energy of the contact velocity is stored as the potential energy due to the elasticity of the rubber. This assumption leads to that the impulse in the horizontal direction is proportional to the contact velocity. The vertical and horizontal...
This paper presents a SIFT based map building and self localization method for mobile robots. First a mapping robot with trinocular vision builds the 3-D keypoint map of unknown environment with a high accuracy and then the working robot with a monocular vision localize the own position by matching the SIFT keypoints to the map. Experimental results of mapping and localization for a real indoor scene...
In this paper, we describe the concept, design and implementation of a series of autonomous mobile soccer robots, named "Musashi" robot, which have a mechatronics modular architecture, to participate in the RoboCup middle-size league. In this design methodology, we show that the selection of a proper moving mechanism, a suitable vision system and a mechatronics modular architecture design...
