Вопросы по младшей возрастной группе WRO 2015

В прошлом сообщении делался анонс о появившихся правилах World Robot Olympiad 2015. На текущий момент доступна первая версия правил, которая еще будет уточняться, после чего 1 марта будет выложена финальная версия.
Поэтому сейчас самое время подготовить вопросы по правилам, чтобы чтобы сформировать четкое понимание какой робот сможет выполнить задачу наиболее эффективно.

Одна из возможных стратегий обсуждения правил - мозговой штурм, когда в одной комнате собираются вместе несколько человек, читают построчно правила и задают все возможные вопросы. Какие-то вопросы решаются сами по себе, а какие-то формулируются для дальнейшего разъяснения. Таким образом убивается сразу несколько зайцев: все заинтересованные в обсуждении правил стороны собираются вместе, у всех собравшихся формируется одинаковое максимально полное понимание текущей версии правил, во время обсуждения правил идет параллельное обсуждение возможных вариантов решения.

Команда Университета Иннополис до нового года собралась своим коллективом и провела такого рода обсуждение доступной версии правил. Вот какие вопросы для организаторов появились в ходе штурма для младшей возрастной группы основной категории WRO 2015 (вопросы и замечания выкладываются на английском языке во избежание двойной обработки).

Если у вас есть чем дополнить этот список - добавляйте свои вопросы в комментариях.
  1. Rules and Regulation, Item #7 (further it will be marked as RR.7). Currently it says 'No part of the robot is allowed outside the large green area before it starts'. Last year we used in-zone and completely-in-zone terms. Could you specify which term is applicable here? Is this for the projection of the robot or only for parts which touch the field.
  2. RR.11. 'The colored LEGO blocks must be pushed into the small colored end zone below the white square where the block is found'. It is not clear here - could the block pushed in any zone or in the particular one which is exactly below the corresponding white square? Depending on the answer the following needs to be clarified: for example there are two red blocks on the field in the sector #3 and in the sector #7 - what is the mechanism to determine if I pushed the first red block from the white square in the sector #3 in the colored end zone in the sector #3 and the second red block from the white square in the sector #7 in the colored end zone in the sector #7. It is possible to imagine a robot who picked up all the blocks and moved them in the different end zones.
  3. There are no sizes for the barriers between zones on the page 8.
  4. Is it possible to imagine a robot that will try to manipulate with the dive time clock as so the clock's sensors will be pressed forever. For example, it can leave its part near to the touch pad and it will be locked in pressed state. Is it allowed?
  5. Who will reset the dive time clock at the start? Will it be done by judges when they say "Start" or it will be done by one of team member at the moment when the "enter" button on the robot is pressed?
  6. The task can be solved without determining colors of the blocks. Imagine, the robot has three sections and needed number of the ping-pong balls are put in the corresponding section by the operator. So, the robot should move to the corresponding large colored zone and unload all balls from the corresponding robot's sections. So, the robot will use just encoders to navigate on the map or one or two sensors to follow the line.
  7. RR.14. Could you clarify the statement "They will bias their decision to the worst outcome available for the context of the situation". We are not sure that understood it properly.
  8. There is no mention in the RR.15 that the attempt will be considered as finished if the robot finishes in the large red area as it is defined in S.5 (the Scoring section, the item #4).
  9. There is no strict requirements for finish: should the robot be completely in zone and stopped, should it be completely in the zone but continue moving or will the timer be stopped if the robot is partially in the zone. Is it for projection of the robot or for the parts which touch the field?
  10. What if the colored block is broken during the movement to the small zone and one of its part is out of this zone whereas the projection of the block itself is one of presented on the left side of the picture in the S.2.
  11. Currently the rule S.6 is not clear in the definition of "the fastest time". Are the recorded times for the corresponding attempts compared? or the fastest time of all attempts of the corresponding team is chosen? I understand that the first way is correct but it needs to be stated so in this case.
  12. What is the process of the draw in the competition? Does it make sense to have the same number of pearls for all rounds during the day of the competition? Otherwise it will be hard to compare time for different teams in the different rounds since the time to unload all ping-pong balls could be different from one attempt to another.
  13. Is maximum of color blocks specified on the page 11? The question is due to the number of pearls specified in RR.10 - judging on this item it could be 9 green blocks on the field.
  14. Usually the table specification mentioned tolerance in 10-50 millimeters. It was needed to foresee errors which can be made during the field development and assembling. Does it make sense to point out it in the specification again in order to reduce number of complains from the teams side?
  15. The item RR.15 does not include action "Any team member touches the game objects on the field after the attempt started"
  16. Is it allowed to robot move over the barriers between small colored zones?
  17. Will be the program for the dive time clock provided? Which software is it for (EV3, NXT, Robolab)?
  18. How the judge will be signaled that the dive time clock expires? In case of big competition it could be several tables with the clocks and a judge could stop the attempt by mistake if the signal from the next table will be heard.
  19. Will all the barriers be rectangle (or square) in profile?
  20. How can the mechanism of pressing the clock be secured as so avoid situations when the robot actually pressed the touch-pad but the sensor did not reflect this.
