Team leader, Sun Yat-sen University, 2020.9 - 2021.1

Mentor: Liang Lin, Professor
Research in bipedal robotics walking control method. Achieved an automatic solution for bipedal robot walking control by reinforcement learning.
In gym with PyTorch, used Walker2D to delve into factors of RL algorithm. Using SAC algorithm, achieve precisely walking in complex 2D circumstance, and simply straight walking in 3D circumstance.

Team leader, Sun Yat-sen University, 2019.2-2020.1

Mentor: Xiaohua Xie, Associate Professor
A project of scientific research internship in the lab of Prof. Xiaohua Xie.
Propose an image overlapping area positioning and fusion method for pedestrian trajectory tracking between multiple vertical cameras, based on OpenCV Aruco.
The method is eventually integrated into the laboratory’s camera products and applied to wide-area passenger trajectory tracking.
