A Unique Multi-functional Landmark for Autonomous Navigation

To save time, improve flexibility and guarantee accuracy of the navigation system of the mobile robots, a multi-function landmark and a new navigation algorithm are proposed in this paper. With the new algorithm and landmark the mobile robots can be located by only a single landmark, and can be navigated in a large area by serial landmarks. The simple configuration and the convenient material of the landmark increased the system´s flexibility and decreased the complexity of the algorithm. From the experimental results it can be concluded that the navigation system has fast navigation speed and high navigation accuracy.
