In this talk, Delong Zhu talked about their experience in the DGI Developer Challenge . His team won the global top 10 in the contest. They have designed and engineered an automonous drone that is capable of tracking moving vehicle, automatically landing on it, and avoiding collision, e.g. collision with trees in the trajectory of flight. With the hardware and SDK provided by DGI, Delong’s team focused on the development of auto-landing, collision avoidance, and terrain coverage algorithm. Their implementation is based on Robot Operating System.
