This project addresses the development of autonomous self- deploying aerial robotic systems (SDARS) that will enable new in-situ atmospheric science applications through targeted observation. SDARS is comprised of multiple robotic sensors and distributed computing nodes including: 1.) multiple fixed-wing unmanned aircraft, deployable Lagrangian drifters, mobile Doppler radar, mobile command and control stations; 2.) distributed computation nodes in the field and in the lab; 3.) a net-centric middleware connecting the dispersed elements; and 4.) an autonomous decision-making architecture that closes the loop between sensing in the field and new online numerical weather prediction tools. The proposed effort draws on the expertise of the project team in the areas of robotics, unmanned systems, networked control, wireless communication, active sensing, and atmospheric science to realize the vision of bringing cloud robotics to the clouds. Combining autonomous airborne sensors with environmental models dispersed over multiple communication and computation channels enables the collection of information essential for examining the fundamental behavior of atmospheric phenomena.
Autonomous self-deploying aerial robotic systems will close significant capability gaps in conventional platform’s abilities to collect the data necessary to answer a wide range of scientific questions. The motivating application for this work is improvement in the accuracy and lead time of tornado warnings. Other science applications that would benefit from the proposed work include thunderstorm outflows and gust fronts; landfalling hurricane boundary layer dynamics; planetary boundary layer physics studies (including many processes relevant to climate dynamics); atmospheric responses to fires; pollutant dispersion monitoring and forecasting; and terrain-driven circulation systems. Curriculum development, mentoring, and outreach activities will emphasize the complexity of modern engineered systems and their potential societal benefits in order to motivate the next gener- ation of scientists and engineers.
