Hongbo Zhang

I am a third-year Ph.D. candidate in the Department of Mechanical and Automation Engineering at The Chinese University of Hong Kong (CUHK). As a member of the Legged Robot Lab (CUHKLRL), I work under the supervision of Professor Yunhui Liu. My research focuses on developing advanced control strategies for legged robots through reinforcement learning approaches. I am particularly interested in bridging the gap between theoretical robotics and practical applications, working to create more robust and adaptable control systems for complex robotic platforms.

Before joining CUHK, I received my B.E. degree in 2022 at Zhejiang University in Automation and Control.

My current research interests focus on robot learning, including:
