Feel free to reach out!

I am a senior undergraduate student in Department of Automation at Tsinghua University. My research interests lie in robotics manipulation, human-robot interaction, and the intersection of control theory and machine learning. I was fortunate to be advised by Prof. Xiang Li and Prof. Mingguo Zhao during my undergraduate studies, and I joined the Stanford Vision and Learning Lab (SVL) as a summer research intern in 2025. In the future, I will pursue my Ph.D. at the Institute for Interdisciplinary Information Sciences (IIIS), Tsinghua University, under the supervision of Prof. Mengdi Xu.

Present UltraDP, a Diffusion-Policy-based method that receives multi-sensory inputs (ultrasound images, wrist camera image, contact wrench, and probe pose) and generates actions that are fit for multi-modal action distributions in autonomous ultrasound scanning. UltraDP achieves a 95% success rate in transverse scanning on previously unseen subjects, demonstrating its effectiveness.
Whole-Body Model Predictive Control for Mobile Manipulation with Task Priority Transition

Yushi Wang, Ruoqu Chen, and Mingguo Zhao

In 2025 IEEE International Conference on Robotics and Automation (ICRA), 2025

Abs Website

Developed a Whole-Body Model Predictive Control (WBMPC) framework to manage task priorities and scheduling in multi-task mobile manipulation scenarios. Integrated task priorities into a unified weight matrix, enabling smooth transitions across tasks in both spatial and temporal dimensions.
