This paper proposes a navigation system of a personal mobility robot in informationally structured and unstructured environments. First, we introduce a group of robots named Portable Go, which are equipped with laser range finders, gyros, and omni-directional wheels. The Portable Go robots expand the informationally structured environment by deploying in the informationally unstructured environment in advance. Then, a personal mobility robot based on an electric wheelchair is guided by eleven Portable Go robots in the new informationally structured environment which is just created by the Portable Go robots. Through navigation experiments, we verify that the proposed system navigates the personal mobility robot from the informationally structured environment to the informationally unstructured environment smoothly by using the Portable Go robots. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

This paper proposes a navigation system of a personality mobility in informationally structured and unstructured environments. With the proposed system, a personal mobility can automatically move in an informationally structured environment where rich sensory information is obtained, a temporary informationally structured environment where a group of mobile sensing robots are deployed and develop a informationally structured environment temporary, and an informationally unstructured environment where no embedded sensors are installed. Experiments show that the personal mobility is guided appropriately from indoor to outdoor by changing the localization and navigation processes.
