Abstract : During 27-29 January 2017, the US Army Research Laboratory (ARL) hosted a software integration event to build a working software-in-the-loop (SIL) simulation environment in support of the US Army Tank Automotive Research Development and Engineering Center Wingman program. Wingman focuses on human-machine collaboration, decision making, human-machine combat teaming, and advanced manned-unmanned teaming operations. Its primary operational objective is to effectively project lethality for first contact with enemy forces, enabling friendly freedom of maneuver. Developing a joint SIL will allow for rapid prototyping, software development, and early assessment by joint services and team members. Developments in the SIL can be directly implemented on real-world vehicles. In addition, this SIL will also provide a simulation test bed for ARL to assess human interaction with manned-unmanned teams during periods without real-world field tests. Outcomes of joint research efforts will support the design of a robotic system user interface and enhance communication among manned-unmanned team members, which are critical to achieve Training and Doctrine Command 6 1 required capabilities for robotics and autonomous systems.
