Abstract
We presented the method to guide and control a mobile robot under the environment informationized by IC tags until now. In ROBOMEC2011, we presented the method to move a mobile robot to a destination while it moves to low potential by using potential field written in IC tags. This paper describes a method to guide a robot by using the composite potential field of fixed potential environment decided by a structure and modifiable potential environment decided by application. For example, the potential field can limit the territory of a robot in a big event site. The experiments show the effectiveness of this method.
