Research

My research interests are primarily focused on Embodied Artificial Intelligence and Computer Vision. My research interests focus on how to achieve broad generalization capabilities for open-world manipulation tasks, the application of Vision-Language-Action models to robots, and inference acceleration.

OpenHelix is a dual-system framework for robotics(VLA Model), which leverages the reasoning capabilities of high-level multimodal large language models (MLLMs) to enhance low-level policies with minimal training cost. This work first summarizes and compares the structural designs of existing dual-system architectures, and then conducts systematic empirical evaluations on their core design elements. Finally, we present a low-cost open-source model to support further research and applications.

SDM Policy distills diffusion-based visuomotor policies into one-step generators via a two-stage process combining score and distribution matching. It uses a dual-teacher setup to enhance robustness and achieves 6 times faster inference.
