Autonomous systems composed of multiple sensors potentially have significant importance in applications while one sensor is not suffice due to interference of signals, limitations in angular range, and malfunctions of sensors in the navigation scheme. Besides the failure of sensors, it is prerequisite to switch the sensor for approaching to the target object from absolute to relative positional sensor. The core work of this contents concerns the coordination and switching of sensors for essential approaching using landmark for agricultural operations. To accomplish the elusive project of...
