GTD and Marshall Aerospace will deliver to the UK Ministry of Defense a Knowledge Management System for semiautonomous robot navigation GTD and Marshall Aerospace have proposed a novel knowledge based approach to providing semi-autonomous tactical navigation for the Assisted Carriage Vehicle concept of the UK MoD Research program, reducing the Burden on the Dismounted Solider (RBDS) Capability Vision (CV). This is achieved through the software development of a Knowledge Management System (KMS) and a Knowledge Acquisition System (KAS), both of which have been tailored following technology transfer from an existing similar aeronautical solution into the land domain. Using information and data from ISTAR sensor platforms, C4I geographic sources, and human expert knowledge the Knowledge Management Solution provides enhanced topological data within current road maps with a higher level of information including associated risks. The Knowledge Management Solution achieves this by a technique of processing optimization of rules and algorithms for a number of variables such as distance, risk, time and mission objective resulting in an appropriate semi-autonomous tactical navigation routes to being calculated The resulting research is demonstrated through a number of use case scenarios validating the development of a software solution that is independent of any specific vehicle platform or sensor suite providing a semi-autonomous tactical navigation platform agnostic solution.
