Section 1. Game Overview
Stars twinkle in their respective constellations, while planets move through the cosmos along established orbits. As humanity embarks on interstellar travel and explores the vast universe, we will investigate the nature and laws of time and space through more precise observations and experiments. This journey will create a new legend and help us better understand the universe's evolution and development.
This competition requires young students to use their self-made robots to write and debug programs and perform competition tasks at the competition site. The theme of this competition is "Interstellar Legend." The contestants will use robots to explore the mysteries of the universe in a simulated environment, thereby popularizing scientific knowledge and training and improving the contestants' thinking, reaction, hands-on coordination, and team spirit.
Section 2. Requirements for the Team
The teams for the competition are divided into four categories:
- Primary school (junior) group (Grade 3 and below),
- Primary school (senior) group (Grades 4-6),
- Junior high school group,
- Senior high school group.
Each team consists of a contestant and a coach. Contestants must still be registered students until June 2025.
Section 3. Robot
3.1 Requirements for Building Equipment
The event requires contestants to design and build robots to complete the corresponding tasks, but there is no need to build them on-site. Only electronic parts with plastic shells and plastic building blocks can be used to build robots. 3D-printed parts cannot be used. During the competition, the robots must not damage the competition field and task models.
Except for the motor, battery box, sensor, remote controller, and camera, all parts of the equipment prepared by the contestants shall not be assembled by screws or welding, and auxiliary materials such as glue and tape are not allowed. By registering for the competition, it is deemed that the organizing committee has the final right of interpretation of these rules.

Section 4. Game Procedure
4.1 Entry Order
The Super AI Super Track competition is a points competition. The participating teams draw lots on the spot to determine the grouping and order of competition and take turns playing in the order determined by the draw.
The organizing committee will ensure that every participating team in the same group has the same chance to play, generally not less than two rounds.
When the previous team starts the game, the next team will be notified to wait and prepare.
Teams that do not arrive within the stipulated time will be deemed to have given up the qualification for the competition.
4.2 Programming and Debugging
The participating teams will have at least 60 minutes to debug their robots before the first round. The referee team will adjust the duration of the debugging according to the actual situation and announce it to all participating teams before each round of debugging.
Contestants are required to program and debug in an orderly manner. Contestants who do not comply with the order may be disqualified. Once programming and debugging are complete, all teams must place their robots in a location designated by the referee and keep them there. Contestants are not allowed to touch robots again without permission, otherwise, they will be disqualified.
After the referee signals the start of the game, the team that is still not ready will lose the opportunity to play in this round, but it will not affect the next round.
4.3 Preparations before the Game
When preparing to go on stage, the contestants take their robots and enter the competition area under the guidance of the referee or staff. Teams that fail to arrive within the specified time will be deemed to have forfeited.
When entering the field, contestants should stand near the Starship Dock and put their robots into the Starship Dock. At this time, any part of the robot and its projection on the ground cannot exceed the Starship Dock.
4.4 Start the Game
After the referee confirms that the team is ready, he will issue a countdown start command of "3, 2, 1, start". As the countdown begins, the contestants can slowly approach the robot with their hands. When the contestants hear the "start" command, they can touch a physical button on the controller to start the robot.
Starting a robot before the "Start" command will be considered a "false start" and will result in a warning or penalty. Once a robot is started, players are not allowed to touch the robot (except for reset).
After starting, the robot must not separate parts or drop mechanical parts on the field. The referee will clear the robot parts that accidentally fall off the field at any time. Separating parts for strategic needs is a foul. If the robot completely crosses the field’s boundary due to excessive speed or program error after starting, or throws the items it carries out of the field, the robot and the items shall not return to the field.
4.5 Time Score
If you complete all the basic tasks and random tasks set by each group within the specified time, you can get a "time score". The completion of additional tasks does not affect the "time score". After the game, the players should immediately signal the referee to stop the timing. The remaining time will be calculated according to the interval described below. (Note: The integer part of the remaining time is taken for calculation, 2 seconds for 2.7 seconds, and 10 seconds for 10.3 seconds.)
(1) If the remaining time is less than 3 seconds, the time score is 0;
(2) If the remaining time is 3 seconds ≤ remaining time < 10 seconds, 5 points are added;
(3) If the remaining time is 10 seconds ≤ remaining time < 20 seconds, 10 points are added;
(4) If the remaining time is 20 seconds ≤ remaining time < 30 seconds, 20 points are added;
(5) If the remaining time is ≥ 30 seconds, 30 points are added.
4.6 Reset
To encourage participating teams to improve program stability and optimize competition strategies, a "smoothness score" is set. 50 points of "smoothness score" are automatically obtained when the competition starts. Every time a reset occurs during the entire mission, the "smoothness score" is reduced by 5 points, with a maximum reduction of 50 points.
Each time a reset occurs, the points obtained are reset to zero, the mission model needs to be restored to the initial state, and the robot returns to the Starship Dock and starts again. When a reset occurs, the timing does not stop.
The robot needs to be reset to the Starship Dock in the following situations:
(1) The contestant requests a reset from the referee;
(2) The robot leaves the competition venue;
(3) The contestant touches the mission model or robot without permission;
(4) In an Advanced Mission, the robot does not move along the flight path or the robot leaves the track line.
4.7 End of Game
If the following situations occur, the competition will end upon the referee's whistle and the time will be recorded.
(1) The robot is unable to continue to perform subsequent tasks;
(2) The team completes the "safe return" task;
(3) The team actively signals the referee to end the competition;
(4) The task time limit is reached.
4.8 Final Score
After each game, the team's single-round score is calculated. The total score of the task is scored according to the task completion standard, see the Descriptions of Elementary Missions or Advanced Missions for details. After all rounds of competition are completed, the highest score of each single game is used as the final competition score of the team.
The time score is the number of seconds remaining at the end of the round, refer to the requirements of "Section 4.5 Time Score".
Single-round score = the score for completed tasks + smoothness score + time score.
4.9 Ranking
After all the games in a certain group are over, all teams will be ranked according to their total score. If two teams have the same score, they will be ranked again according to the following criteria:
(1) The team with the higher total score in the two rounds will be ranked higher.
(2) The team with the shorter completed time in the two rounds will be ranked higher.
(3) The team with the fewer reset times will be ranked higher.
(4) The team with the fewer motors and sensors used by the robot will be ranked higher.
Section 5. Descriptions of Elementary Missions
The following description of Elementary Missions only applies to the Primary School (Junior) Group. Teams control the robot to complete tasks by program control or remote control. The robot can arrange the order of completing the tasks by itself. After completing the task, all robots of the team must return to the designated area to end the game.
The competition consists of an automatic period and a remote-control period, totaling 120 seconds, of which the automatic period takes up to 10 seconds and the remote-control period takes up to 110 seconds. During the automatic period, the robot must complete the tasks set in the field through program control; during the remote-control period, the contestants can operate the robot through the remote controller to complete the tasks set in the field. The remote-control period can only start after the automatic period ends.
For the task models, please refer to the diagrams below the task description. Note that the actual task models in the competition may differ. For example, the beams, connector pegs, and other structures may come in different colors or vary slightly in size and height. Contestants should be capable of making adjustments based on the actual conditions.

5.2.5 Interstellar Scientific Research (Additional Task)
(1) Before programming and debugging begin, the referee randomly draws lots to decide whether to add the Interstellar Scientific Research task to the game. If so, the task model of the Interstellar Scientific Research will be covered in mission area C2. The referee will randomly adjust the task model's orientation based on the field's situations.
(2) The model mainly comprises a lever, a scientific research device, and four constellations. The four constellations are set up on the left and right sides of the scientific research device. The four surfaces of the scientific research device are pasted with patterns of the four constellations.
(3) After the robot pushes the operating lever to make the scientific research device rotate more than one circle, the contestant needs to operate the robot to push down the corresponding constellation on the left or right side according to the constellation pattern on the side of the scientific research device facing the operating lever, so that it changes from a vertical state to a horizontal state.
(4) If the robot causes the limiter to engage, 10 points will be scored. If the corresponding constellation on the front of the scientific research device is pushed down to a horizontal state, 50 points will be added. It can be scored if only one corresponding constellation is pushed down among the four constellations. No points will be awarded if more than one or the wrong constellation is pushed down.

Additional tasks may be assigned on-site for Junior High and Senior High School groups and will be announced before debugging. The task model of the additional task will be set in the corresponding area according to the requirements.
6.2.1 Smooth Departure
(1) The robot leaves the Starship Dock.
(2) If the robot's vertical projection completely leaves the Starship Dock at the beginning (only one record per round of the competition), 60 points will be awarded.
6.2.2 Flight Path
(1) On the flight path of the entire field, there are several dotted lines perpendicular to the flight path, which divide the entire flight path into multiple sections. English letters such as "A, B, C" are marked in order.
(2) The robot must move forward in the direction of the flight path throughout the whole process. If the robot needs to perform other tasks, it can briefly deviate from its current flight path to reverse. (After completing these tasks, it must return to the point of deviation and continue on its original path.) The two driving wheels of the robot must be located on both sides of the flight path or just cover the flight path’s track line.
(3) If any driving wheel of the robot touches a marked line on the flight path, 6 points will be awarded, with a full score of 60.

6.2.4 Event Horizon Exploration
(1) Detector models are randomly set up on some flight paths, with at least one set for the primary school (senior) groups and at least two sets for the junior and senior high school groups. Two soft rubber strips with a length of 410 mm, a width of 10 mm, and a height of 10 mm are set at the dividing line between the event horizon and the apparent boundaries of the black hole.
(2) The detector model is a dodecahedron with a length, width, and height not exceeding 50 mm. Before programming and debugging begin, the referee randomly draws a letter representing the marked line on the flight path. After confirmation, the referee will directly cover the detector model at the intersection of the corresponding marked line and the flight path.
(3) When the robot reaches the detector, it picks up the detector and delivers it to the black hole in the center of the field. When the detector leaves the initial placement point, the task is completed and 10 points are scored for each move.
(4) If the detector touches the apparent boundaries of the black hole, 10 points will be added for each; if the detector touches the black hole's event horizon, 20 points will be added for each; if the detector touches the center of the black hole, 30 points will be added for each touch. If the detector touches both areas at the same time, the highest score of the two will be used for extra points.
(5) During the entire process of the robot picking up and delivering the detector, the robot's vertical projection must always remain in contact with the track line and not touch the black hole area, otherwise it will be considered an invalid operation.

6.3 Randomness of Tasks
Except for "Starship Navigation" which is fixed in mission area A1, the additional task "Interstellar Scientific Research" is fixed in mission area A2, "Space-Time Distortion" is fixed at marked line E, and the locations of the task models of "Event Horizon Exploration", "Hatch Unfolding" and "Supplies Loading" are not fixed. Before programming and debugging start, the referee determines the location and direction of the task models by drawing lots, according to the task requirements.
6.4 Time Limit
The duration of a single round is 180 seconds.
6.5 Off the Track Line
During the movement, the robot is not allowed to deviate from the track line of the flight path (that is, the robot's driving wheels must touch or be on both sides of the black line, and must pass through all track lines along the way). If the robot completely deviates from the black line, it must be reset.
For completing tasks other than the "Event Horizon Exploration" task, the robot can temporarily deviate from the track line but must return to the original deviated location before continuing to drive.
- Violations
7.1 Each team is allowed to "false start" the robot once in each round of the mission. If the second "false start" occurs in the group stage, the score for that round will be 0 points, and in the finals, the team will be eliminated directly.
7.2 After the start of the game, if a contestant touches objects or robots on the field without the referee's permission, they will be warned for the first time, and their score for the second time will be 0 points.
7.3 If the coach or parents give verbal instructions that affect the contestants' performance, personally participate in the building and debugging, or touch or repair the works, the score for that round will be recorded as zero once verified.
7.4 After starting, the robot shall not deliberately separate parts or drop parts on the field for strategic needs. If the robot does this, it will be considered as a foul and a warning will be given as determined by the referee. If the violation occurs again, the score for this round will be 0 points. Parts that are separated or dropped due to foul play will be cleared immediately by the referee.
7.5 If a contestant fails to follow the referee's instructions, the referee will assess the severity of the situation and take appropriate action. The contestant may receive a warning, a score of 0 in the preliminary round, elimination from the final, or even disqualification from the event.

Mission Challenge LEGO
The goal of this category is to build a robot at the competition and conduct a designated mission on the day of match.
This category is meant for young robotics enthusiasts that want to compete with other participants at a beginner to medium level. The age limit for this category is 16 years.
General specifications
The robot and the solution for the mission must be solved only using a robot built out of Lego Mindstorms devices (RCX, NXT, EV3 or Spike Prime).
Under the rules of the game, teams will have to build at the competition an autonomous robot, that will have to accomplish the mission according to the mission specifications received at the start of the competition while also respecting the specifications in the regulations.
1. Notification
We realize that there are other variations to the rules for Mission Challenge, while there are many similarities between other variants the official Robotics Championship rules posted on the website will be used, for this competition we ask that participants to read and be familiar with this particular rule set at the time of the competition, in order to avoid surprises.
This category is inspired by the games organized by the International Robot Olympiad Committee (IROC). (see more at https://www.iroc.org/2018-rules-1 )
2. Team
2.1. A “team” is composed of one to five participants who will build a robot at the event. Each team should also have one adult present with the team. One adult can represent multiple teams if they wish.
2.2. The robot must be an autonomous robot constructed by themselves at the competition site to regulation and mission specifications. This robot category does not permit prebuilt robots, kits will be inspected before the start of the category. There will be a predefined time for adjustments and changes to the robots and their programming during the event.
2.3. Each team / robot will receive a check-in number and should have a unique name or identity to be easily recognizable by spectators and officials when they are on the field and when they score. The identification label will be placed on the robot during the technical inspection after the building of the robot is done.
2.4. Each team that has built a robot for this category will have equal chances and number of tries. During the trials, only two members can approach the track, the other team members must follow the trial from the public or remain in the participants area.
