The competition adopts a national unified proposition and regional organization, and the competition adopts a "semi-closed, relatively centralized" organization. During the competition, students can consult papers or relevant technical materials in the network, and students in the team can collectively discuss design ideas, determine design schemes, be responsible for division of labor, unite and cooperate, and independently complete the competition tasks with the team as the basic unit.
During the competition, no teacher or other personnel shall give any form of guidance or guidance; During the competition, participants are not allowed to discuss with anyone outside the team. The participating schools should concentrate the students in the laboratory for the competition, so as to facilitate the organization of personnel inspection. In order to ensure the competition, all participating schools are responsible for providing the equipment and parts needed for the competition.
