Navigation path scanning system for mobile robot by laser beam

We propose the system for the mobile robot navigation with a laser source on the ceiling. At first, users make a navigation path which shows where the mobile robot should go. Base on the navigation path information, the laser spot is automatically irradiated to the ground. Then, the mobile robot detects the position of the laser spot by the optical sensor array and follows the trajectory of the laser spot. In this paper, we describe the scanning method of the navigation path that uses the laser.
