Autonomous Learning to Robotic Swarm Tactics

Meta-Reinforcement Learning Innovation for Robust Swarm Tactics

Charles River Analytics received funding from DARPA under the OFFensive Swarm-Enabled Tactics (OFFSET) program to develop Meta-Reinforcement Learning Innovation for Robust Swarm Tactics (MERLIN-RST). MERLIN applies a meta-reinforcement learning approach to discover and learn novel swarm tactics.

MERLIN uses a meta-reinforcement learning approach so swarms can autonomously learn new tactics

“MERLIN explores a rich, complex, and unpredictable search space that describes the many possible forms a tactic can take and automatically optimizes it to a wide range of mission goals.”

Senior Scientist on the MERLIN project

Through biology-inspired algorithms and deep machine learning, tactics in the OFFSET program help swarms achieve and adapt to mission objectives. However, human programmers cannot support the evolution of these tactics quickly or accurately enough—numerous variants in adversary strategy and evolving environments make manual development a challenge that may lead to system failures or brittle tactics.

“MERLIN explores a rich, complex, and unpredictable search space that describes the many possible forms a tactic can take and automatically optimizes it to a wide range of mission goals,” said Michael Harradon, Senior Scientist at Charles River Analytics and Principal Investigator on the MERLIN effort. “We’re laying the groundwork for a highly flexible design process that can dramatically improve swarm effectiveness.”

Under the MERLIN effort, Charles River is augmenting OFFSET simulators to model swarm performance in a wide range of challenging urban environments as part of the OFFSET Program’s Fourth Swarm Sprint. MERLIN builds on our recent successes under the OFFSET program. With SATURN, we developed capabilities that give heterogeneous swarms of unlimited size resilient behavior while achieving mission objectives. Our EUROPA effort helps operators better control swarms in urban operations by providing novel, multimodal user interfaces tailored to tactical operational environments.

Our OFFSET participation complements other techniques and applications we have developed to support autonomous and uncrewed systems, such as the MINOTAUR interface for controlling robotic leader-follower systems, the AMPT framework for supervising uncrewed vehicles, and the CROWSNEST maritime traffic awareness solution for an uncrewed surface vessel.

Our deep understanding of applied robotics and autonomy is the result of extensive research and development across many disciplines, such as artificial intelligence, machine learning, cognitive science, and human factors. Our decades of experience deploying our solutions into the field uniquely positions us to provide mature and tailored solutions for our customers’ needs.
