A computing anticipatory system must have the ability to make decision about its next action. To design and develop various computing anticipatory systems effectively , it is desirable to find a general methodology for decision making in computing anticipatory systems. This paper presents a deontic relevant logic approach to reasoning about actions in(More)
Epistemic Programming has been proposed as a new programming paradigm for scientists to program their epistemic processes in scientific discovery. As the first step to construct an epistemic programming environment, this paper proposes the first epistemic programming language, named 'EPLAS'. The paper analyzes the requirements of an epistemic programming(More)
This paper introduces an obstacle avoidance control for a mobile robot using a single CCD camera and ultrasonic sensors. First, the mobile robot detects an obstacle based on information of both the image and the distance. Then, from the information obtained about the obstacle, the mobile robot generates a trajectory to avoid the obstacle. Finally, the(More)
This paper treats the navigation problem of a mobile robot based on vision information and ultrasonic data. In our method, by calculating the optical flow on the images, the mobile robot can detect obstacles which exist ahead of it, further avoiding the area of obstacles, it can make the optimal trajectory to the final goal. Then, in order to generate the(More)
The purpose of this paper is to measure the working radius of a crane truck by using vision systems. Then, we introduce the observation device which is equipped with a CCD camera, a laser range finder and two AC servo motors. Further, we propose new algorithm for the mark recognition and then construct PID control system with an extended Kalman filter in(More)
