Development of Unmanned Ground Vehicles (UGVs) has been ongoing for decades. Much of the technology developed for UGVs can be applied directly to Unmanned Surface Vehicles (USVs) with little or no modification. SPAWAR Systems Center San Diego (SSC San Diego) has successfully demonstrated this by transitioning technology (both hardware and software) from a man-portable UGV to a USV demonstrator platform. By transitioning technology already proven in a UGV, SSC San Diego was able to develop a working USV much more quickly than would have been otherwise possible. The technologies ported from the UGV to the USV include: the software architecture and protocol, teleoperation, a Kalman filter for state estimates, waypoint navigation, the Operator Control Unit (OCU), miniature processors, Ethernet switches and a video CODEC board.
