These rules are formulated in accordance with the Articles of Association of the National Seaplane Design and Manufacture Competition. The jury of the contest should follow these rules when grading the entries.
Article 1 The basic principles of grading work
1. According to the competition category, the entries are divided into creative design category, physical production category and ship model intelligent navigation category.
In the process of grading, first consider the specific requirements of different competition categories, and then comprehensively consider the innovation, scientificity, feasibility and economic application value of the works. The grading of creative design works is divided into two parts: material review and on-site defense. The jury will review the recommended works and then arrange on-site defense for the shortlisted works. The referee committee scores the two parts respectively, and each part is always divided into the final comprehensive score, according to which the award-winning grade of each work is judged. 4. The grading of physical production works is divided into three parts: material review, physical demonstration and on-site defense. The referee committee will review the recommended works, arrange physical demonstrations for the finalists, and finally organize on-site defense. The referee committee graded the three parts respectively, and each part was divided into the final comprehensive score, according to which the award-winning grade of each work was judged.

You can't turn on the machine at will. By then, the stadium will be equipped with frequency scanners and GPS signal monitoring equipment. Violators will be disqualified.
Competition mode: The day before the competition, each team has two hours of flight test time to familiarize themselves with the venue. During the competition, a maximum of four players from each team can play. Complete the preparation for trial training within 10 minutes after the participants enter the venue.
According to the aircraft's navigation attitude, route navigation, crossing the width-limited gate (or avoiding obstacles), power mode, navigation control mode, accuracy and stability of navigation control, and anti-overload structure design, score and set additional points. Scoring includes navigation scoring and function scoring, and the system design report is used as scoring reference. Each scoring item is scored by the judges, and the average score is included in the total score. Each award is named according to the score.

Third, ship model intelligent navigation
1, competition form
Competitors can make and buy semi-finished products or commodity models by themselves, and set the model according to the sailing route to sail the competition automatically.
2. Competition venue
Aoxiang Swimming Pool in Chang 'an Campus of Northwestern Polytechnical University (50 meters long, 2 1 meter wide and 2 meters deep, with photoconductive width-limiting door on the water surface).
Total model weight: the sum of model weight and load, with the heavier one scoring; The carrying capacity is determined randomly by the organizing Committee in the specified specifications.
Model power supply: standard battery designated by the organizing Committee before the competition.
3. Rules of the game
The model must pass through each photoelectric gate on the navigation route in turn as required, and those that fail must come again, otherwise the guidance signal of the next gate cannot be turned on. Timing starts when the model leaves the landing platform and ends when it passes through the last door.
There are two rounds in the competition, and the time of each round is 10 minute. Anyone who completes the voyage according to the specified route within 10 minutes shall be deemed as valid, otherwise there will be no result. Two rounds of competition can use the same or two different models to participate in the competition, and take the best result as the competition result.
Before the competition, the contestants' models were submitted to the judging committee for inspection, and the length, weight and batteries used were recorded. After the model is checked, it will be sealed until the start of the game. Before the start of the competition, the models will be handed over to the contestants in the order of the competition, and after the competition, the models will be returned to the staff.
Technical requirements for ship model intelligent sailing competition are attached.
Step 4 prepare for the game
On the day before the game, each team always has two hours to try familiar venues. During the competition, a maximum of four players from each team can play. Complete the preparation for trial training within 10 minutes after the participants enter the venue.
5. Score points
Sailing achievements are recorded by the effective time of model sailing records, with the shortest time as the first, and the rest are analogized.
The comprehensive score consists of two parts: the effective time of the model navigation record and the model weight, and the points will be deducted according to the following provisions.
The model with the shortest time (100) among the valid results of navigation records is divided into the model with the longest time (0) and the time records of other models are the percentage between them;
Take the model with the heaviest weight 100 as the base, and the model with the lightest weight is 0, and the weight between them is converted into the number of components by percentage;
After the above two results are added up, it is the final score of the contestants, and the highest score is the first place, in this order.
