This paper considers a trajectory navigation control of a mobile robot by a CCD camera and ultrasonic sensors. First, the robot detects the obstacle by information of both image and distance. Further, based on the detected obstacle information, the robot generates a trajectory to avoid the obstacle safely without colliding with it. Finally, we show usefulness of our proposed method through experiment.
This paper considers a path planning of a mobile robot by single CCD camera and a scan range finder. First, the mobile robot detects the obstacle based on information of both the image and the distance. Then, from the obstacle information, the mobile robot generates a trajectory to reach a final destination avoiding the obstacles. Finally, usefulness of proposed methods is shown through experiment.
This paper introduces a control method for obstacle avoidance of a mobile robot. First, the mobile robot detects obstacles by information of both a CCD camera and ultrasonic sensors. Then, using information of both of camera and sensors, the mobile robot generates a dynamic trajectory to go to the goal point avoiding the obstacles. Through some experiments, a usefulness of proposed method is shown.
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 order to realize the system without the time...
In this paper, we develop the observation device which measures the working radius of a crane. To realize the measurement, the observation device has the CCD camera and the laser range finder, and the specific mark is attached to a crane. Then, we propose methods for the object recognition and the tracking control. As for the tracking control, to realize the control system without time delay, we construct...
