Behavior-based mobile robot using active sensor fusion

Abstract

The authors present a navigation system using multiple sensors for unknown and dynamic indoor environments. To achieve robustness and flexibility in the mobile robot, a behavior-based system architecture is developed consisting of multilayered behaviors using multiple sensors that were ultrasonic sensors and a video camera. Basic behaviors required for navigation, such as avoiding obstacles, moving toward free space, and following targets are redundantly developed as agents and combined in a behavior-based system architecture. The capabilities of the system were demonstrated in unstructured real office environments using an indoor mobile robot.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
