This paper presents a fuzzy system approach that incorporates sensing, control and planning to enable micro wall climbing robots navigating in unstructured environments. Based on a fuzzy multi-sensor data fusion scheme, a novel strategy for integrating task scheduling, sensing, planning and real-time execution is proposed so that task scheduling, action planning and motion control can be treated in a unified framework, and the design of task synchronization becomes much easier. A hybrid method is employed to create robot's gaits by switching the robot between continuous motion modes with the help of a finite state machine driven by the signals from robot sensors. For a highly non-linear system as the micro wall climbing robot, a fuzzy motion controller is designed to improve the robot's performance at different situations. Experimental results prove the validity of the proposed method.
