Abstract: The present invention discloses a wireless charging system for Q-UGVs, housed in a robust build. The wireless charging system is housed in a weatherproof box and is capable of charging more than one Q-UGV, thus baggage and fatigue of having to maintain multiple charging stations for multiple systems. An improvement in the system is expedited charging for two Q-UGVs, which is ideal environments wherein autonomous and persistent security is necessary and is capable of receiving and transmitting charging commands from the Q-UGV.

Abstract: A navigation system provides pose, i.e., location and orientation, solutions using best available location information from two or more location systems. One of the location systems is a fiducial-based location system, which is accurate when a sufficient number of fiducials is recognized. However, when an insufficient number of fiducials is recognized, an odometry-based location system is used. Although the odometry-based location system is subject to drift, when a sufficient number of fiducials is recognized, the fiducial-based location system is used to correct the odometry-based location system. The navigation system provides robust, accurate and timely pose solutions, such as for augmented reality (AR) or virtual reality (VR) systems, without the time-consuming requirement to establish and localize many fiducials or the computational and memory requirements of pure fiducial-based location systems, and without the inherent drift of pure odometry-based location systems.
