🙋About Me

I am a master student of Robotics Institute at Carnegie Mellon University (CMU). Prior to that, I received my bachelor degree from Southern University of Science and Technology (SUSTech), with a major in Robotics Engineering.

I am broadly interested in robotics planning and control, and I hope to focus on legged systems in the future.

🤖 Projects

NMPC controller for Wheel-leg robot

A nonlinear model predictive controller based on ocs2 and ros-control. The floating-base dynamics was derived under the base frame, so there is no need for state estimation.

RL based whole-body operation controller for quadrupedal robots

My undergraduate thesis. We trained a controller to make the robot climb, lean on the wall, and use its forelimbs to press a point on the wall.

3-Dof Hopping controller for Delta Hopper Robot

A hopping controller for CMU GOAT robotic leg. The robot can jump in all directions at desired height and velocity when its orientation is constrained.

RoboMaster Teach Pendant

A Visual-SLAM based teach pendant for Robomaster ‘Engineer’ robot.

RoboMaster 'Hero' robot and 'Engineer' robot

Competition robots designed for Robomaster 2021 season. I was responsible for the embedded system software development.

Oculus-ROS

ROS Interface for Oculus Quest 2 based on the ROS# Unity plugin and Oculus Unity integration.

Cheetah Seven

DND Character, Warforged (quadrupedal), level 7 clockwork sorcerer.
