Information Fusion for Autonomous Robotic Weeding

: Information fusion has a potential applicability to a multitude of different applications. Still, the JDL model is mostly used to describe defense applications. This paper describes the information fusion process for a robot removing weed in a field. We analyze the robotic system by relating it to the JDL model functions. The civilian application we consider here has some properties which differ from the typical defense applications: (1) indifferent environment and (2) a predictable and structured process to achieve its objectives. As a consequence, situation estimates tend to deal with internal properties of the robot and its mission progress (through mission state transition) rather than external entities and their relations. Nevertheless, the JDL model appears useful for describing the fusion activities of the weeding robot system. We provide an example of how state transitions may be detected and exploited using information fusion and report on some initial results. An additional...
