The 19th China Robocon was held on Nov. 6-8, 2020 online by use of the Tencent Meeting, and the contest was live webcasted to all interested audiences with the help of the Bilibili website.

Considered that the teams' preparation activities for the contest were interrupted for about nine months as the epidemic of new coronavirus pneumonia, and a real game field was hard set in the campus for the room limitations, some simplifications, such as the game field and the robot actions, were made based on the real ABU Robocon 2020 rulebook to encourage more teams to participate. Two basic robot missions, Pass and Goal Kick, were selected to display the strength of the team in the contest. Finally, 75 universities completed the contest safely, orderly and wonderfully. The referees and the contestants kept real-time communications through the Tencent Meeting. The audience watched through the live broadcast platform, and the anchorman explained the whole process.
