For autonomous systems such as unmanned aerial vehicles to successfully perform complex missions; a great deal of embedded reasoning is required at varying levels of abstraction. To support the integration and use of diverse reasoning modules we have developed DyKnow; a stream-based knowledge processing middleware framework. By using streams; DyKnow captures the incremental nature of sensor data and supports the continuous reasoning necessary to react to rapid changes in the environment.

DyKnow has a formal basis and pragmatically deals with many of the architectural issues which arise in autonomous systems. This includes a systematic stream-based method for handling the sense-reasoning gap; caused by the wide difference in abstraction levels between the noisy data generally available from sensors and the symbolic; semantically meaningful information required by many high-level reasoning modules. As concrete examples; stream-based support for anchoring and planning are presented.
