Mobile Robot Navigation Using Trajectory of Laser Spot

Abstract

This paper proposes the system for a mobile robot navigation with a laser source on the ceiling. At first, users make a map which shows where the robot should go. Based on the map information, the laser spot is automatically irradiated to the ground. Then, the mobile robot detects the position of the laser spot by the photo transistor array and follows the trajectory of the laser spot. The proposed system is implemented and confirmed the feasibility through several basic experiments.
