Robot Navigation Using Camera by Identifying Arrow Signs

Robot navigation is an active area of research. In this paper, we emphasize on the image processing algorithms for the navigation of robots. A track with left and right arrow signs is provided for navigating the robot from one end of the track to the other end. The navigation is done by identifying the arrows signs and making the decisions to either turn left or right based on the direction of the arrow signs. We selected four different features to isolate the arrow region in the image from rest of the regions. Further, we exploited the shape of the arrow to decide on the direction of the arrow. We found that the robot accurately navigates through the track with left and right arrow signs and it reaches the destination successfully.
