    A Persistent Simulation Environment for Autonomous Systems

    The age of Autonomous Unmanned Aircraft Systems (AUAS) is creating new challenges for the accreditation and certification requiring new standards, policies and procedures that sanction whether a UAS is safe to fly. Establishing a basis for certification of autonomous systems via research into trust and trustworthiness is the focus of Autonomy Teaming and TRAjectories for Complex Trusted Operational Reliability (ATTRACTOR), a new NASA Convergent Aeronautics Solution (CAS) project. Simulation Environments to test and evaluate AUAS decision making may be a low-cost solution to help certify that various AUAS systems are trustworthy enough to be allowed to fly in current general and commercial aviation airspace. NASA is working to build a peer-to-peer persistent simulation (P3 Sim) environment. The P3 Sim will be a Massively Multiplayer Online (MMO) environment were AUAS avatars can interact with a complex dynamic environment and each other. The focus of the effort is to provide AUAS researchers a low-cost intuitive testing environment that will aid training for and assessment of decisions made by autonomous systems such as AUAS. This presentation focuses on the design approach and challenges faced in development of the P3 Sim Environment is support of investigating trustworthiness of autonomous systems

    The Effects of Commercial Video Game Playing: A Comparison of Skills and Abilities for the Predator UAV

    Currently, Predator unmanned aerial vehicles (UAV) are operated by pilots and navigators experienced with manned combat aircraft. With a projected increase in UAVs, more combat pilots will be needed to operate these aircraft. Yet, if the current operational tempo continues, the supply of combat pilots may not be able to meet the demand. Perhaps alternative pools of Air Force personnel could be considered for UAV duty to meet operational requirements. Because the Predator UAV is a software-driven aircraft, video game players (VGPs) already possess and use many skills that may be similar to those of Predator UAV pilots. A variety of games can add situational awareness skills that a player/airman can bring to a new situation. This research examines the applicability of video-games-based skills to the operation of the Predator UAV. Nine people were interviewed to determine the overlap between piloting skills, UAV-specific skills, and skills gained and developed from gaming. The results indicate that frequent VGPs have the confidence and the consistent ability to obtain and retain new skills, many of which are related to operating the Predator UAV in a 2-D environment while not relying on the visual and nonvisual cues of the manned aircraft pilot

    Performance Analysis of WebRTC-based Video Streaming over Power Constrained Platforms

    This work analyses the use of the WebRTC framework on resource-constrained platforms. WebRTC is a consolidated solution for real-time video streaming, and it is an appealing solution in a wide range of application scenarios. We focus our attention on those in which power consumption, size and weight are of paramount importance because of size, weight and power requirements, such as the use case of unmanned aerial vehicles delivering real-time video streams overWebRTC to peers on the ground. The testbed described in this work shows that the power consumption can be reduced by changing WebRTC default settings while maintaining comparable video quality
