Lingao robot ROS2
A wannabe beach cleaning Robot but in simulation still roaming the grass. The goal is to use the coverage planner to drive up a specified area and filter big particles out of the sand, like a vacuum cleaning robot but on the beach.
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.
