Abstract

A navigation strategy for an autonomous land vehicle (ALV) based on the Defence Geographic Database is currently being developed under the auspices of. the Mobile Advanced Robotics Defence Initiative (MARDI). The database is hierarchically structured, and supports the storage of an unlimited number of attributes for each geographical feature. It also expressly identifies the interconnectivity of adjacent features, making it ideal for automatic route calculation. Tactical battlefield information is being combined with the database resulting in a composite link-node map which will be searched for optimum routes using standard algorithms. Both military and geographical criteria will be simultaneously optimized. Waypoints suitable for machine vision techniques will also be extracted and used to confirm the ALV location.
