Humanoid locomotion & loco-manipulation · Robot learning

I am a final-year PhD student at Harbin Institute of Technology, advised by Prof. Zongwu Xie. I make humanoid robots learn to walk, see, and work in the real world.

I am currently with the HONOR Robotics team as a core contributor to its humanoid robots, which debuted at MWC 2026 in Barcelona, won the 2026 humanoid half-marathon, and broke three human world records at the 2026 World Humanoid Robot Games.

I also created LeggedLab, an open-source RL workflow for legged robots.

Collaborations and conversations are warmly welcome.
