On the Utility of Koopman Operator Theory in Learning Dexterous Manipulation Skills

CoRL 2023oral

Despite impressive dexterous manipulation capabilities enabled by learning-based approaches, we are yet to witness widespread adoption beyond well-resourced laboratories. This is likely due to practical limitations, such as significant computational burden, inscrutable learned behaviors, sensitivity…

Geometric Fabrics: Generalizing Classical Mechanics to Capture the Physics of Behavior

RA-L 2022

Classical mechanical systems are central to controller design in energy shaping methods of geometric control. However, their expressivity is limited by position-only metrics and the intimate link between metric and geometry. Recent work on Riemannian Motion Policies (RMPs) has shown that shedding th

Neural Geometric Fabrics: Efficiently Learning High-Dimensional Policies from Demonstration

CoRL 2022poster

Learning dexterous manipulation policies for multi-fingered robots has been a long-standing challenge in robotics. Existing methods either limit themselves to highly constrained problems and smaller models to achieve extreme sample efficiency or sacrifice sample efficiency to gain capacity to solve…

Generalized Nonlinear and Finsler Geometry for Robotics

ICRA 2021poster

Robotics research has found numerous important applications of Riemannian geometry. Despite that, the concept remain challenging to many roboticists because the background material is complex and strikingly foreign. Beyond Riemannian geometry, there are many natural generalizations in the mathematic…
