Information regarding the environment surrounding remote mobile robots, such as images, sensors, and sounds, is necessary for the effective control of these robots.However, it is difficult to control the remote mobile robot safely because of the delay in receiving the image information and inaccuracies in the sensor information.We aim to reduce the problems occurring during the control of the remote mobile robot and propose a safe method for navigating the robot to the target point.We require a map that shows the surrounding environment, location presumption of the robot, and an obstacle perception technique. We draw the environment map using an infrared ray sensor. It is difficult to discriminate distance information using one-dimensional image information.However, we propose to solve this problem using a virtual stick that represents different distances with different colors.The aim of our study is to improve the perception of the position and distance of the obstacle using the virtual stick and the safe navigation of the remote mobile robot avoiding collision with obstacles.
