: Reactive Real-time Flow Policies

Sungjae Park, Shubham Tulsiani

Generalist manipulation policies increasingly take the form of action-chunking flow policies built on large pretrained backbones. Such chunks run open-loop, so the policy cannot re…

Dex4D: Task-Agnostic Point Track Policy for Zero-Shot Dexterous Manipulation

Yuxuan Kuang, Sungjae Park, Katerina Fragkiadaki +1

Learning generalist policies capable of accomplishing a wide range of everyday tasks remains an open challenge in dexterous manipulation. In particular, collecting large-scale mani…

Temporal Score Rescaling for Temperature Sampling in Diffusion and Flow Models

Yanbo Xu, Yu Wu, Sungjae Park +2

We present a mechanism to steer the sampling diversity of denoising diffusion and flow matching models, allowing users to sample from a sharper or broader distribution than the tra…

BG-HOP: A Bimanual Generative Hand-Object Prior

Sriram Krishna, Sravan Chittupalli, Sungjae Park

In this work, we present BG-HOP, a generative prior that seeks to model bimanual hand-object interactions in 3D. We address the challenge of limited bimanual interaction data by ex…

DemoDiffusion: One-Shot Human Imitation using pre-trained Diffusion Policy

Sungjae Park, Homanga Bharadhwaj, Shubham Tulsiani

We propose DemoDiffusion, a simple method for enabling robots to perform manipulation tasks by imitating a single human demonstration, without requiring task-specific training or p…

Learning to Transfer Human Hand Skills for Robot Manipulations

Sungjae Park, Seungho Lee, Mingi Choi +4

We present a method for teaching dexterous manipulation tasks to robots from human hand motion demonstrations. Unlike existing approaches that solely rely on kinematics information…

DROID: A Large-Scale In-The-Wild Robot Manipulation Dataset

Alexander Khazatsky, Karl Pertsch, Suraj Nair +98

The creation of large, diverse, high-quality robot manipulation datasets is an important stepping stone on the path toward more capable and robust robotic manipulation policies. Ho…
