Abstract
To operate a mobile robot by remote control with safety, the operator needs to know around the robot to avoid obstacles. In this study, we use a vision system with wide field of view in order to acquire images around the robot. Then, we propose a method to show nearness of an obstacle in the image by LED and antenna. The operator can confirm the safety of the robot in the image by observing a movement of the light projected on the wall or antenna comes contacting with an obstacle. In addition, we evaluate the usefulness by experiments and show the result in this paper.
