Lingyu (Tom) Xiao

Hi there! I am currently a PhD student at The University of Hong Kong (HKU), supervised by Prof. Xintao Yan. I obtained my MSc in Control Science and Engineering from Southeast University in 2025, supervised by Prof. Wankou Yang.

My research interests include:

  • Generative Simulation
  • Perception & Decision-making
  • Multi-modal Machine Learning

Many of my undergraduate projects focused on embedded systems and robotics (ROS, Gazebo, etc.). Selected projects are listed here.

Feel free to contact me by email if you are interested in discussing or collaborating with me.

Projects

Line-Following and Treasure-Hunting Robot

RoboCup Competition, 2021 National 1st Prize in Robot Tourism Group
Techniques: Electronic design, Mechanical Design, Control, Computer Vision
Full Video

The project requires robots to complete exploration and treasure-hunting tasks within 180 seconds, testing planning, adaptability, positioning, climbing, and obstacle-crossing abilities, while balancing speed and stability.

Autonomous Driving Robot

University Students Intelligent Car Race, 2021 National 3rd Prize in Creative Group
Techniques: Computer Vision, Mechanical Design, Control
