UniDex: A Robot Foundation Suite for Universal Dexterous Hand Control from Egocentric Human Videos

CVPR 2026

Dexterous manipulation remains challenging due to the cost of collecting real-robot teleoperation data, the heterogeneity of hand embodiments, and the high dimensionality of control. We present UniDex, a robot foundation suite that couples a large-scale robot-centric dataset with a unified vision-la

Reactive Diffusion Policy: Slow-Fast Visual-Tactile Policy Learning for Contact-Rich Manipulation

RSS 2025poster

Humans can accomplish complex contact-rich tasks using vision and touch, with highly reactive capabilities such as quick adjustments to environmental changes and adaptive control of contact forces; however, this remains challenging for robots. Existing visual imitation learning (IL) approaches rely…

3D Diffusion Policy: Generalizable Visuomotor Policy Learning via Simple 3D Representations

RSS 2024poster

Imitation learning provides an efficient way to teach robots dexterous skills; however, learning complex skills robustly and generalizablely usually consumes large amounts of human demonstrations. To tackle this challenging problem, we present 3D Diffusion Policy (DP3), a novel visual imitation lear…

DIFFTACTILE: A Physics-based Differentiable Tactile Simulator for Contact-rich Robotic Manipulation

ICLR 2024poster

We introduce DIFFTACTILE, a physics-based differentiable tactile simulation system designed to enhance robotic manipulation with dense and physically accurate tactile feedback. In contrast to prior tactile simulators which primarily focus on manipulating rigid bodies and often rely on simplified app…

Learning to Manipulate Anywhere: A Visual Generalizable Framework For Reinforcement Learning

CoRL 2024poster

Can we endow visuomotor robots with generalization capabilities to operate in diverse open-world scenarios? In this paper, we propose Maniwhere, a generalizable framework tailored for visual reinforcement learning, enabling the trained robot policies to generalize across a combination of multiple vi…

Robo-ABC: Affordance Generalization Beyond Categories via Semantic Correspondence for Robot Manipulation

ECCV 2024poster

"Enabling robotic manipulation that generalizes to out-of-distribution scenes is a crucial step toward the open-world embodied intelligence. For human beings, this ability is rooted in the understanding of semantic correspondence among different objects, which helps to naturally transfer the interac…

Thin-Shell Object Manipulations With Differentiable Physics Simulations

ICLR 2024spotlight

In this work, we aim to teach robots to manipulate various thin-shell materials. Prior works studying thin-shell object manipulation mostly rely on heuristic policies or learn policies from real-world video demonstrations, and only focus on limited material types and tasks (e.g., cloth unfolding).…

Flexible Handover with Real-Time Robust Dynamic Grasp Trajectory Generation

IROS 2023poster

In recent years, there has been a significant effort dedicated to developing efficient, robust, and general human-to-robot handover systems. However, the area of flexible handover in the context of complex and continuous objects' motion remains relatively unexplored. In this work, we propose an appr…

Relative Entropic Optimal Transport: a (Prior-aware) Matching Perspective to (Unbalanced) Classification

NeurIPS 2023poster

Classification is a fundamental problem in machine learning, and considerable efforts have been recently devoted to the demanding long-tailed setting due to its prevalence in nature. Departure from the Bayesian framework, this paper rethinks classification from a matching perspective by studying the…

Understanding and Generalizing Contrastive Learning from the Inverse Optimal Transport Perspective

ICML 2023poster

Previous research on contrastive learning (CL) has primarily focused on pairwise views to learn representations by attracting positive samples and repelling negative ones. In this work, we aim to understand and generalize CL from a point set matching perspective, instead of the comparison between tw…
