Lingao robot ROS2
The vision is to have a robot going up and down the beach. By covering some area it should filter out dirt from the sand and clean up the beach like a vacuum cleaning robot. I tested some methods for SLAM and navigation on the real robot in my living room. The coverage planner and GPS navigation is already implemented in the simulation. However this project is still in progress.
GPS Waypoint Follower
I used the flight controller from my crashed drone and put it on the rc-car won from the autonomous rc-car race. And boom I got an autonomous rover that can follow gps coordinates set up in Ardupilot as the mission planner.
Autonomous RC-car race (first place) 
In this competition organized at HKUST I trained the Jetson-racer to drive autonomously, avoid obstacles and overtake other cars. Basically I drove along the race course and recorded images with the corresponding throttle and steering values. This data is fed into the a ML model and let it train. It was much fun and I resliced what machine learning is capable of but also it's limitations.
