This paper introduces the basic Rapidly-Exploring Random Tree (RRT) and its basic modification Rapidly-Exploring Random Tree star (RRT*), which is not only the extension of RRT, but also a widely applied algorithm because of the properties of asymptotically optimal path regardless of any obstacles, whereas the limitation to achieve optimal path has a slow convergence rate. As a result, it costs too...
This paper proposes a complete robot location system: monitor moving robot in household environment and get its accurate physical coordinates to provide assistance information for robot decision making system. Firstly, video flow retrieved from a multi-camera system is processed by an object tracking system, which is based on AdaBoost algorithm and Haar-like features with a slight improvement. Secondly,...
Aimed at project instructional courseware design using geometrical painting method which is an sample of multimedia courseware, an suggestion was made that design should be directed by appropriate teaching and learning theory, bring forth all materials to learner through appropriate technology, making the learner to be able to join into the whole process of learning, to practice all the related technique...
Computer simulation, as a mode of instruction using, played a positive role in teaching during these years. However, the simulation experiment design of the teaching and learning environment still remains problems. This paper focuses on the simulation experiments design in teaching and learning environment.
