The Laboratory for Autonomous Systems Research (LASR), Code 1700 of the Naval Research Laboratory (NRL) provides facilities, equipment and other resources that enable research in the fields of robotic and autonomous systems (RAS), communication and navigation, human robot interaction and machine learning. To better support this research, the LASR facility requires a high-fidelity digital twin of its facilities, equipment and platforms. The Digital Twin will accurately model and simulate the physical environments and various assets within the LASR facility, providing NRL researchers with an easily accessible tool for simulating robotic and autonomous system (RAS) behaviors in realistic digital environments. The Digital Twin shall enable controlled exploration and extensive test and evaluation of RAS across a wide range of conditions in a cost-effective manner not afforded by the physical environment. NRL is seeking information from sources that may be capable of providing a solution that will achieve the requirements indentified in this notice and within the Statement of Work (SOW) attached.
