1. Outline of the Contest

Each team consists of no more than three robots: one manual and one or two automatic robots. The manual robot must complete the first task by picking up three Joss Stick Pots and placing them at Common Zone before performing other tasks. After that, the manual robot will bring a Candle Base and place it at Decoration Point located on Sala. The manual robot will collect Joss Sticks from the Common Zone to be used again during Krathong assembly.

The automatic robots will collect Krathong Petals and Flowers and place them at Preparation Points. The automatic robots will decorate Krathong by stacking one Krathong Petal and then one Flower on the Candle Base located on Sala. After completing this task, the manual robot will then place three Joss Sticks into the decorated Krathong. The automatic robots will carry the completed Krathong and drop it on River Surface of its own side. No part of any robots can touch or contact the River Surface.

Lastly, the automatic robots will bring and drop a Candle Light Flame on top of the Candle in the completed Krathong floating on the River Surface. No part of any robots can touch or contact the River Surface or the completed Krathong. The first team that drops the Candle Light Flame successfully is the winner of the match. This type of winning is called "Loy Krathong".

If neither team achieves the "Loy Krathong" within 3 minutes, the winner shall be decided by the earning scores of the completed tasks.

Each match is contested by Red and Blue teams. A match lasts 3 minutes.

5. Competition Tasks and General Restrictions

Once the game has begun, each team shall complete the tasks:

  1. The Manual Robot picks up three Joss Stick Pots and places them at any Poles in the Common Zone. The three Joss Stick Pots include two Joss Stick Pots which belong to its team and one Joss Stick Pot which belongs to the other team. Without completing this task, the manual robot is not allowed to do other tasks, likewise, the automatic robots are not allowed to start.
  2. The Manual Robot brings the Candle Base and places it at the Decoration Point on the Sala.
  3. The Automatic Robots collect Krathong Petals and Flowers from the Storage Points and place them at the Preparation Points only from the ground field.
  4. The Automatic Robots move up the Sala and bring a Krathong Petal and a Flower from the Preparation Points. The automatic robots stack a Krathong Petal on the Candle Base at the Decoration Point, and then stack a Flower on the Krathong Petal.
  5. The Manual Robot collects any Joss Sticks that belong to its team which are considered from color of the Joss Sticks from the Common Zone and places three Joss Sticks at the three holes of the decorated Krathong on the Sala. During placing the Joss Sticks, the Manual Robot is allowed to touch the decorated Krathong at the Decoration Point.
  6. The Automatic Robots carry the completed Krathong and drop it on the River Surface. No part of the robots is allowed to touch the River Surface either directly or indirectly.
  7. Only the Automatic Robots can bring a Candle Light Flame and drops it on top of the Candle in the completed Krathong floating on the River Surface. No part of the robot is allowed to touch the completed Krathong or the River Surface directly or indirectly. In any cases of dropping the Candle Light Flame on the Game Area, the dropped Candle Light Flame cannot be reused any further in the match.

  8. Some restrictions are enforced in the game as follows.

  9. In any cases of dropping the Candle Light Flame on the Game Area, the dropped Candle Light Flame cannot be reused any further in the match.
  10. In the case of dropping the Joss Stick Pots, the Joss Sticks or the Candle Base, the Manual Robot can pick up the dropped Joss Stick Pots, the Joss Sticks or the Candle Bases if they are inside its own Game Area including the space above. The dropped Joss Stick Pots, the Joss Sticks and the Candle Bases can then be reused again.
  11. The Automatic Robots can do any tasks of the Manual Robot.
  12. The Manual Robot can be switched to become an Automatic Robot after placing three Joss Stick Pots at the Common Zone with permission from the referee. The switching process must be done in any Automatic Staring Zones. Once the Manual Robot is switched and become the Automatic Robot, it cannot be reversed back to become the Manual Robot again.
  13. If a Krathong is not completed, no score for dropping that Krathong on the River Surface is given. Likewise, no score for dropping the Candle Light Flame on the Candle of the incompleted Krathong is given.
  14. In the case of dropping the Krathong Petals, Flowers, Joss Sticks, Joss Stick Pots, or the Candle base, they will be returned to their respective Storage Points.


6. Retries of Robots

  3. Retries of a robot or several robots at the same time can be made as many times as necessary.
  4. A retry of Manual Robot is made at Manual Start Zone only.
  5. A retry of Automatic Robot is made at either Automatic 1 Start Zone or Automatic 2 Start Zone.
  6. During a retry, the team can request the referee to bring the dropped Krathong Petals or Flowers back to their previous locations; back to the Storage Points or back to the Preparation Points if they are successfully placed earlier. The earned score still remains.
  7. During a retry, the team can request the referee to bring the completed Krathong that was dropped on the way to the River Surface back to the Decoration Point. The earned score still remains.
  8. During a retry, the team can bring all the objects which are held by the robots during asking for the retry back to the Start Zones. However the dimension of each robot and its objects in the Start Zone must follow the rule on starting the robots written in 8.5 and 8.6. Otherwise the objects will be considered as the dropped objects.
  9. During carrying Joss Stick Pots to the Common Zone if the Manual Robot drops the Joss Stick Pots, the team members are allowed to bring the Joss Stick Pots back to the Storage Points of the Joss Stick Pots. In this case a retry is compulsory.
  10. The Automatic Robots are not allowed to place Krathong Petals or Flowers to the Preparation Points while they are on the Sala. This action causes violation and a retry is compulsory. The Krathong Petals and Flowers which were placed to the Preparation Points by this action will be brought back to the Storage Points.
  11. During dropping the completed Krathong on the River Surface, if any parts of the Automatic Robots or the Krathong held by the robots physically touch the River Surface either directly or indirectly, this action causes violation and a retry is compulsory. The team has to restart the Automatic Robots that made the violation at the Automatic Start Zones. The referee will remove the dropping Krathong out of the Game Area. That Krathong cannot be reused any further in the match.
  12. During dropping the Candle Light Flame on top of the Candle in the completed Krathong floating on the River Surface, if any parts of the Automatic Robot or the Candle Light Flame held by the robot physically touch the Candle, any parts of the Krathong, or the River Surface either directly or indirectly, this action causes violation and a retry is compulsory. The team has to restart the Automatic Robot that made the violation and the other Automatic Robot that holds the Candle Light Flame, if any, at the Automatic Start Zones. The Automatic Robots that still hold the Candle Light Flames during this action are allowed to bring the Candle Light Flames to the Automatic Start Zones. However the dimension in the Automatic Start Zones must follow the rule on starting the Automatic robots written in 8.5, otherwise the Candle Light Flames must be brought back to the Storage Points of the Candle Light Flame.
  13. The Automatic Robot is not allowed to hold the Candle Light Flame and the completed Krathong at the same time. This action causes violation and a retry is compulsory. The Candle Light Flame will be brought back to the Storage Point of the Candle Light Flame and the completed Krathong will be brought back to the Decoration Point.
  14. Strategies premised on the use of retries are allowed.
