2. Competition Field and Environment

Field

The competition field measures 120cm x 120cm (Figure 1) and is made of PU cloth or spray-painted cloth. The two robot bases measure 25cm x 25cm.

Competition Field Environment

The competition field is equipped with fixed boundaries. The environment is characterized by coldlightsources,low illumination, and the absence of magnetic field interference. However, due to the many uncertainties ingeneralcompetition field environments, such as surface textures, unevenness, varying lighting conditions, anddifferentmodelfixation methods, teams are not allowed to modify the field factors on-site, especially the fixation methods of thefieldand task props. Teams should consider various countermeasures when designing their robots.

3. Robot tasks and scoring

Please note that the following tasks are merely simulations of real-life scenarios and should not becomparedtoactual life situations.

Robot Starting Position and Scoring

The robot begins its task from a designated starting point, which is referred to as the "base".
If any robot completely leaves the base and none of its vertical projections are within the base, 20 points are awarded.

Rice Transplanting Task

On both sides of the map, there are 4 rice seedlings (approximately 5cm green square, EVA material), as shown in Figure 2.
Scoring criteria: If a seedling is located in the rice field area (part or all of its vertical projection is within the rice field area), 10 points are awarded for each seedling.

Sending Animals Home

There are 4 random locations on the map where piglets (approximately 5cm red square, EVA material)and lambs (approximately 5cm blue square, EVA material) are placed, as shown in Figure 3.
Scoring criteria: If an animal is located in its home (part or all of its vertical projection is within the home), 20 points are awarded for each animal.
The starting positions of the two animal models will be randomly selected before the competition begins.

Fruit and Vegetable Picking

On the map, grapes and tomatoes (approximately 5cm purple squares, EVA material) are placed on shelves close to the middle partition, as shown in Figure 4. Below the field is a food storage warehouse, as shown in Figure 5.
3.4.2 Scoring criteria: If the grapes or tomatoes are finally placed on the base, 20 points are awarded for each. If the grapes or tomatoes are finally placed in the storage warehouse (without touching the map), 40 points are awarded. See Figure 6 for reference.

4. Robots

Robot Size: Before each launch at the base, the robot's dimensions must not exceed 25 cm x 25 cm x 25cm(length x width x height). The robot's structure can expand autonomously after activation.
Controller: In single-wheel competitions, the controller cannot be replaced. The controller's dimensions must not exceed 12cm x 8cm (length x width).
Actuator: Each robot is only allowed to use the motors that come with the robot controller. External motors are not allowed.
Sensors: There is no limit to the type or quantity of sensors that each robot can use.
Structure: Robots must use plastic snap-fit and screw-based structures. Pins, shafts, and bushings can be used to secure the robot. Other structural dimensions must be based on a 20mm unit. 3D printed parts are not allowed. Rubber bands, cable ties, rivets, glue, tape, and other auxiliary connecting materials are not allowed.
Power: Each robot must have its own independent battery compartment and cannot be connected to an external power source. The battery voltage must not exceed 5V, and voltage boosting, stepping down, or regulating circuits are prohibited.
Teams: Each team is allowed two robots, and the sharing of robots among multiple teams is prohibited.

Programming equipment: Must be controlled using handheld remote controls, programmers, and other devices (excluding mobile devices such as smartphones, iPads, and tablets), as shown in Figure 7.

5. Competition

Teams
1. Each participating team shall consist of 2 students and 1 coach. Students must be currently enrolled in school as of June 30, 2025.
2. Team members should approach and independently handle all problems encountered during the competition with a positive attitude. They should respect themselves and others, treat teammates, opponents, volunteers, referees, and all those who have worked hard for the competition with friendliness and respect, and strive to cultivate themselves into individuals with sound personalities and healthy minds.
Competition format
1. The competition will be held in the preschool group.
2. There will be no preliminary or final rounds. The organising committee guarantees that each team will have the same number of appearances, and each appearance will be scored.
3. After all rounds of the competition, the sum of each team's scores in each round will serve as the team's total score, and teams will be ranked according to their total scores.
4. The competition organizing committee may modify the competition format based on the actual situation of team registration and venue.
Competition Process
- Robot Assembly and Debugging

- Pre-Competition Preparation

During the competition, team members should take their robots and enter the competition area under the guidance of the referee. Teams that do not arrive within the specified time will be considered to have forfeited.
Place the robot inside the base. No part of the robot or its projection on the ground can extend beyond the base.
Arriving team members should use this time (no more than 1 minute) to prepare for the start. During the preparation period, the robot cannot be started. After completing the preparation, team members should signal to the referee.

- Start

After the referee confirms that the teams are ready, a countdown of "3, 2, 1, start" will be issued. Upon hearing the "start" command, team members can start the robot.
Starting the robot before the "start" command will be considered a "false start" and may result in a warning or penalty.

- Retry

Retry will be considered if the robot encounters the following situations:
（1）A contestant touches a robot outside the base. （2） The robot completely rushed out of the field.
Retry: If a retry occurs, the field conditions remain unchanged, and the team must move the robot back to the base.
Tasks Completed: Tasks completed before a retry remain valid. However, any models carried by the robot when it returns to the base for a retry become invalid and will be kept by the referee until the end of the round.
Retry Limit: There is no limit to the number of retries per match. The timer does not stop or restart during retries.

- Autonomous Return to Base

Multiple Returns: The robot can autonomously return to the base multiple times without counting as a retry.
Return Criteria: A robot is considered to have returned to the base when any part of its vertical projection falls within the base area.
Team Interaction: After autonomously returning to the base, team members can interact with the robot and make structural changes or repairs.

- End of Match

Time Limit: Each match is 150 seconds long.
Early Termination: If a team completes all desired tasks and does not wish to continue, they should signal their referee. The referee will stop the timer and end the match. Otherwise, the match will end when the referee announces it.
Power Off and No Contact: After the referee announces the end of the match, team members must immediately turn off the robot's power and avoid touching the robot or any objects on the field. If a team member or the robot causes a change in the model's state, points will not be awarded for that task.
Scoring and Disputes: The referee will inform the team of the score. Teams have the right to correct the referee's scoring. If there are no objections, the team should sign to confirm their score. If there is a dispute, the head referee will make a final decision.
Resetting the Field: Team members must restore the field to its starting state and immediately move their robot back to the preparation area.

6. Scoring

Task Completion: Points are awarded based on the tasks completed in the field. If a completed task is accidentally damaged by the robot or team member before the end of the match, points will not be awarded for that task. The scoring criteria for completing tasks can be found in Section 3.
Task Order: The order in which tasks are completed does not affect the points awarded for individual tasks.
Fluency Bonus: If there are no retries during the match and the robot's movements are smooth and continuous, a fluency bonus of 20 points will be awarded. For 1 retry, a 15-point bonus; for 2 retries, a 10-point bonus; for 3retries, a 5-point bonus; for 4 or more retries, a 0-point bonus.

7. Fouls and Disqualification

If a team fails to arrive within 15 minutes of the start of the competition setup, they will be disqualified from that round.
For the first false start, the team will receive a warning from the referee, and the robot will return to the standby area for a restart, with the timer reset. A second false start will result in the team being disqualified from that round.
If a robot collides with the field facilities at high speed, causing damage, the team will receive a warning from the referee. A second instance of damaging the field facilities will result in the team being disqualified from that round.
If a team member or the robot damages a competition model, the team will receive one warning. The points forthattask will be invalidated.
If a non-competing team member interferes with the competition, the corresponding team will be disqualified, and the interfered team will have a rematch.
If a team member touches a competition model outside the base on the field during the competition, that model will become invalid, the competition will immediately stop, and the score will be calculated based on the current state.
Failure to follow the referee's instructions will result in disqualification from that round.
If a team member accesses the internet, downloads any data, or takes photos of the competition field during the competition, the team will be disqualified from that round.
If a team member contacts their coach or parents without the referee's permission, the team will be disqualified from that round.

8. Ranking

Each group will be ranked based on its total score. In case of a tie, the following criteria will be used to determine the final ranking:
- Teams with the lowest total time across all rounds will be ranked first.
- The team with the fewest retries across all rounds will be ranked first.
- Teams with the highest maximum score across all rounds will be ranked first
Winners will be determined based on the team's ranking according to their scores (teams with zero points or those who have forfeited will not be included in the ranking). Awards will be given for first place, second place, third place,firstclass, second class, and third class.
