We present insight into how contextual awareness can be derived from, and improve, a fusion algorithm combing a WSN and a\npassive RFID for autonomous mobile robot navigation. Contextual awareness of not where the robot is, but rather the context in\nwhich it exists in relation to the environment and human user serves to improve accuracy in navigation, alters the speed of the\nrobot, andmodifies its behavior. TheWSN system, using a virtual potential field, provides fast general navigation in open areas and\nthe RFID provides precision navigation near static obstacles and in narrow areas. We verified the effectiveness of our approaches\nthrough navigational and guidance experiments.
