The Mobile Detection Assessment Response System (MDARS) is a joint Army-Navy effort to field interior and exterior autonomous platforms for security and inventory assessment functions at DoD warehouses and storage sites. Based on a Cybermotion K2A Navmaster platform designed for singular operation in structured office environments, the MDARS Interior platform has incorporated additional collision avoidance, intruder detection and inventory assessment systems under a Multiple Robot Host Architecture (MRHA). The MRHA is a distributed multiprocessing system that provides coordinated control of multiple autonomous vehicles from a single host console. The increased functionality of the base platform required the addition of sensor equipment and accompanying distributed processing.
