About Me
I am a PhD student @ General Robotics Lab - Duke (MEMS), advised by Dr. Boyuan Chen, where I am currently working on field robotics with multi-agent systems, aiming to enable robust collective intelligence in uncertain environments.
I hold an MPhil & a BEng (1st Hons) from Hong Kong PolyU (AAE). My research/studies were fully funded via Presidential Research Fellowship & APEC Scholarship. I also did an academic exchange at UQ Australia (AE).
Previously, I was a member @ AIRO Lab mentored by Prof. Chih-Yung Wen & Dr. Boyang Li. I also worked as a RA @ HKCRC, a research institute led by Prof. Zexiang Li.
Up'til now, my focus has been on UAVs, UGVs, UUVs, & multi-agents (homo/heterogeneous), with experiences in v-SLAM, traj-opt, MPC, Lyapunov-based control & dynamics. Feel free to ping me for discussions if any of the above interests you; my RTT is usually low :)

Fun
A Bootcamp for Legged Robotics via Biped and Quadruped Simulation [Code]
Self-implemented biped simulator with feedback linearization and a gait controller for a quadruped using Gazebo ROS. Algorithms and methods employed include Euler-Lagrange modeling, the RK Dormand–Prince method, fixed-point searching on Poincaré maps, forward and inverse kinematics, trajectory optimization with polynomials, feedback linearization, quadratic programming, and cycloid trajectories.
Bipedal Robot Design with Duke Robot Studio [Code]
Designed and built a compact bipedal robot, Rockie, in Duke Robot Studio using a 4-servo actuation setup and a sine-wave gait controller. The project focused on achieving stable walking behavior in a small-form-factor platform, with gait stability evaluated under a Poincaré map assumption. Design considerations emphasized compact mechanical packaging, lightweight structure, embedded actuation, and repeatable locomotion performance.
Toy Convex Solver [Code] [PDF]
Self-implemented a convex solver for equality-constrained minimum-snap trajectory optimization. Algorithms and methods employed include the infeasible start Newton's method and convergence analysis.
An Autonomous UGV with LOAM [Code-SITL] [Code-Firmware]
This implementation showcases an autonomous UGV that employs an open-source LOAM algorithm and a custom-developed nonholonomic car controller utilizing PID-feedforward control. The system was demonstrated on the AgileX Mini platform. Additionally, the corresponding Gazebo SITL simulation environment, including the controller, is maintained and open-sourced.
Bug Planner Implementation for Nonholonomic Planner Robots [Code]
This is an implementation of a nonholonomic path planner for robots during my undergraduate studies. Algorithms and methods employed include 2D lidar scan data processing, 2D wheel robot dynamic modeling, the Bug algorithm for path planning, and 2D wheel robot PID control.
