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 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 optimal trajectory, the distance between a...
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.
Today, vision systems for robots had been widely applied at many important applications. But 3-D vision systems for industrial uses should face to many practical problems. Here, a vision system for bio-production has been introduced. Clone nursery plants are one of the important applications of bio-technology. Most of the production processes of clone nursery plants are highly automated, but the transplanting...
Technique of image processing to detect moving objects on time series images is important subject in the fields of environmental monitoring and rescue system which used a mobile robot. In the past, it is difficult to detect the moving objects by the effects of changes in brightness which caused by the sunlight and measure positions of the moving objects by the change of region of the moving objects...
