Research Questions: How can we coordinate connected robot fleets that are cooperating with a diverse array of stakeholders to achieve their group objectives?  Can we scale the autonomy with the fleet size and geographic span with minimal re-configurations in long-term?

I research along  game theory and deep multi-agent reinforcement learning to extend the fleet autonomy with long-term scalability and cooperative decision-making, focusing on the inter- and intra-fleet interactions.

  • (2022 August) I presented our work on graphical game-theoretic swarm control at IEEE RO-MAN (International Conference on Robot and Human Interactive Communication (RO-MAN).
  • (2022 June) Presented my research on graphical game -theoretic control at University of Sydney.
  • (2022 May) I presented at the Workshop on Intelligent Aerial Robotics , International Conference on Robotics and Automation – 2022, Philadelphia.
  • (2022 March) A new paper accepted to IEEE Robotics and Automation Letters (RA-L): “CoCo Games: Graphical Game-Theoretic Swarm Control for Communication-Aware Coverage” [Paper].

Online Flocking Control of UAVs with Mean-Field Approximation

In this work we cast the aerial swarm flocking as a probabilistic inference and utilize mean-field approximation to infer the control actions for the robots in real time. This allows achieving dynamically feasible real-time flocking control with convergence guarantees borrowed from graphical games.

Flocking of Multi Aerial Vehicles Generation of flocking behavior for UAV swarms in confined areas.
