Agile and Controllable Omnidirectional Fast-Start Maneuvers of Robotic Fish Via Bio-Inspired Reinforcement Learning

ICRA 2026poster

Fast-start maneuvers—exemplified by the C-start in fish—represent a highly agile and very attractive locomotor strategy that requires precise multi-joint coordination under conditions of unsteady fluid dynamics, and has evolved through extensive predator–prey interactions in natural environments. Re…

A Spatiotemporal Downwash Modeling for Agile Close-Proximity Multirotor Flight

IROS 2025

Accurate aerodynamic interaction modeling in multi-drone tasks is crucial for enhancing system stability and efficiency, especially when facing major disturbances from downwash wake effects. Conventional data-driven and empirical models mainly address simplified cases where one drone hovers or all v

Learning Flow-Adaptive Dynamic Model for Robotic Fish Swimming in Unknown Background Flow

IROS 2025

Robotic fish face considerable challenges in natural environment due to the absence of a comprehensive and precise model that can depict the intricate fluid-structure interactions, particularly in the presence of background flow fields. To this end, we present a novel data-driven dynamic modeling fr

Multi-Level Progressive Reinforcement Learning for Control Policy in Physical Simulations

ICRA 2024poster

Training model-free intelligent agents in complex real-world scenarios using reinforcement learning (RL) often necessitates simulation-based environments due to high physical expenses. However, when simulation takes a long time, e.g., in an unsteady 3D fluid simulation with interactions to the contr…
