Flexible Multitask Learning With Factorized Diffusion Policy

RA-L 2026

Multitask learning poses significant challenges due to the highly multimodal and diverse nature of robot action distributions. However, effectively fitting policies to these complex task distributions is often difficult, and existing monolithic models often underfit the action distribution and lack

Hybrid Diffusion for Simultaneous Symbolic and Continuous Planning

RA-L 2026

Constructing robots to accomplish long-horizon tasks is a long-standing challenge within artificial intelligence. Approaches using generative methods, particularly Diffusion Models, have gained attention due to their ability to model continuous robotic trajectories for planning and control. However,

Multi-Modal Manipulation Via Multi-Modal Policy Consensus

ICRA 2026poster

Effectively integrating diverse sensory modalities is crucial for robotic manipulation. However, the typical approach of feature concatenation is often suboptimal: dominant modalities such as vision can overwhelm sparse but critical signals like touch in contact-rich tasks, and monolithic architectu…

\textcolorMaroon\texttt{OAT}\textcolorMaroon\texttt{OAT}\textcolor{Maroon}{\textbf{\texttt{OAT}}}: Ordered Action Tokenization

RSS 2026poster

Autoregressive policies offer a compelling foundation for scalable robot learning by enabling discrete abstraction, token-level reasoning, and flexible inference. However, applying autoregressive modeling to continuous robot actions requires an effective action tokenization scheme. Existing approach…

Implicit Graph Search for Planning on Graphs of Convex Sets

RSS 2024poster

Smooth, collision-free motion planning is a fundamental challenge in robotics with a wide range of applications such as automated manufacturing, search \& rescue, underwater exploration, etc. Graphs of Convex Sets (GCS) is a recent method for synthesizing smooth trajectories by decomposing the plann…
