The project addresses fundamental research to develop novel autonomous and adaptive monitoring systems for natural resources across large spatio-temporal scales using networks of aerial robots equipped with visual sensors. The robots will be able to autonomously adapt to the observed phenomena and to multiple, often conflicting, time-varying constraints and mission specifications, greatly improving the precision of the collected data, and allowing spatio-temporal scalability. This is achieved by considering tradeoffs between visual sensing, real-time trajectory planning, decision making, and system optimization.

The goal of this project is to create the knowledge to facilitate effective and efficient collaborative perception on top of a set of independent and multi-modal data generating agents. The project studies how to jointly model social and sensor data and use this modeling to efficiently support spatio-temporal queries on the joint embedding space. In addition to mapping information from multi-modal disparate sources to a common information space, the project studies how to optimize the attention routing of controllable agents like UAVs to maximize the reliability and coverage of the collected information.

This project investigates the mechanisms that uncertainties in robot-environment interactions affect (small) robot behavior. Small robot motion is more stochastic since errors at the actuators and uncertain interactions with the environment amplify errors in pose. The goal is to introduce a platform-agnostic, data-driven modeling framework to quantify uncertainty and subsequently exploit it via control for reliable robot navigation under uncertainty. The specific aims are to: 1) extract dynamics using limited data for modeling uncertain systems; 2) synthesize uncertainty-aware model-based controllers based on derived reduced-order models; and 3) test and validate theoretical analysis and derived models and control algorithms with aerial, ground, and marine robots. Spectral methods are used to extract spatio-temporal dynamics and to quantify uncertainty. A model-reference adaptive control scheme utilizes extracted dynamics and uncertainty for reliable robot navigation. While the basic principles developed in this research are grounded on small robots, this project's findings may generalize to larger robots with limited sensing and noisy actuation.

This project focuses on foundational principles that enable integrated sensing and analysis in large-scale, multi-modal, multi-agent networks with weak supervision, leading to reliable decision-making in complex, dynamic and uncertain environments while being resilient to adversarial interactions. This overarching goal is achieved through the integration of 1) learning multi-agent, multi-modal models with limited supervision and 2) enabling reliable decision making in collaborative and decentralized robotic teams. The project's tasks involve solid theoretical analysis and algorithm development, e.g., optimization strategies, computational complexity, performance bounds, etc., and are complemented with a rigorous evaluation.
