Frequently Asked Questions (FAQ)
<<UPDATE>> For Point 8.1 in the General rules booklet “During preliminary rounds of WRO Presentation segment, all teams are required to showcase a short video of their robot completing missions according to the challenge requirement.” Please take note that this is not compulsory. It is only applicable for teams who intend to compete for the programming awards. Click here to refer to updated General rules.
1. For rule 3.7, teams are not allowed to use instructions etc. to assemble their robot. However, as teams will also have to present on the same day, they would have materials with the complete robot, which can constitute as building instructions. I would like to know how you will handle this situation as teams will inevitably need their presentation materials. E.g. will presentation materials have to be placed in a separate room from the competition hall?
Each team is only allowed to bring 1 laptop and to be used strictly for programming purpose. Additional materials for presentation can be kept by teachers or trainers until presentation time. Teams will start off with the robot game before proceeding with their presentation.
2. I would also like to know why the number of runs teams are allowed has been reduced to 2 for the preliminaries, as it is WRO standard for the scores of the day to be determined by a best-of-3 format.
NRC is independent of WRO, the National Organiser have the final say of the format.
3. How many 2-min rounds are there during competition day and finals?
There will be 2 runs for the preliminary round and 1 run on Finals
4. Are cables subjected to the 25x25x25cm limit during inspection?
All cables and LEGO parts are to follow the limit for inspection.
5. What does the 150 minutes preparation time consist of? Does it include calibration, programming and testing after the robot is completely built?
Please refer to Challenge Manual Point 6.1
6. What does it mean by disassembling all parts? Every single unit part? Any limit on the number of parts to bring?
Please refer to Challenge Manual Point 3.6
7. What do I do if my EV3e set does not have the security sticker?
Any LEGO MINDSTORMS Education EV3 set which does not bear the LEGO Education authorised distributor/partner security sticker at its battery compartment is required to submit an official letter of authenticity from LEGO Education. Teams are required to submit these letters to the NRC committee at firstname.lastname@example.org before 17 August 2018. Teams who fail to do so may result in disqualification.
8. What does it mean by an identical/similar robot? Will teams be given a first warning or immediately disqualification?
The team will be given a First warning to modify the robot in 10mins before their run.
We agree with you that such a rule should be clearly stated within the official challenge manual. We had the intention to have it included but why we missed it out in the first edition was perhaps due to some subsequent oversight. Hence, we thank you for spotting this. That said, the subsequent documents, ie FAQs, posted online at the competition website should be read on top of the manual as there is constant review or clarifications that we need the participants to be informed of. Information on these documents will be as relevant as the main challenge manual and participants have been reminded to check the website for such updates. For your understanding, please.
On your query regarding the rule, we have intention to enforce it as it strongly encourages the students to not fully rely on a standard solution from peers, mentors or trainers. Our definition of an identical/similar robot is one where it is functionally and physically the same as another, ie built from the same base parts in an identical configuration. We do allow for tweaks to a single solution where for example, the students base their design off one from their peers, mentors or trainers but made modifications to parts to alter function or look to a degree deemed sufficiently original. An example of an original robot can be one where the students modify the gripper attachment with say two extra extension, thus allowing the robot to hold an object with 4 vs 2 digits. This functional enhances the robot as it can better grasp the object. As for an example where the modification is insufficient, say a team dress up their robot with extra attachments that serve no function and only serve to make the robot look more complex or aesthetically appealing, will be deemed as an identical/similar robot to another that has no such attachments.
Our intention is not to penalise students but rather to spur them to think beyond model solutions handed to them. I believe that you will agree with me on where we are coming from, which is for the good for the students. Adding on, our officials will exercise our discretion in issuing such warnings. There will not be any immediate disqualifications and student will be allowed to modify their robots on the spot and continue with the competition.
WRO Primary (Elementary)
1. Can the fruits be thrown into the zones? Or gently placed? What about kicked in? for example https://www.youtube.com/watch?v=IBrsBW64MIQ
2. If a team is assigned points at first but got zero after scoring penalties, will any points be assigned when the robot goes back to base after that?
WRO Secondary (Junior)
1. Under the scoring segment, 5th box, ‘All soil quality data blocks touch the white square of their initial locations. Points are only given if at least one plant in a farm gets points and no plant is placed in a farm not matched with soil quality data’. Does the one plant refer to the green plants as well? Or only for red and yellow.
Only for Red and Yellow
2. Under the scoring segment, 6th box, ‘Remaining 5 plants touch the grey squares around their initial locations in the Seedling Area. Points are only given if at least one plant in a farm gets points’. What does it mean by touch? Must it be fully within or partially? Must it be the upright position? Can it be slightly damaged?
Fully within, upright and undamaged.
3. Last box in the scoring area, what does it mean by ‘if other points are assigned’? Does it mean that it has to be a positive score? Or an attempt to score would do? Regardless if succeed or failed.
Teams will have to succeed in scoring positive points in order to get the last 10 points. This is regardless if there is a penalty or not.
4. Are the teams allowed to bring in building instructions?
Please refer to Challenge Manual Point 3.6
5. Referring to the score sheet, 5th segment ‘All soil quality data blocks touch the white square of their initial locations. Points only are given if at least one plant in a farm gets points and no plant is placed in a farm not matched with soil quality data. What does it mean by not matched? Must all 4 yellow/red plant be placed correctly? What if only 2 plants placed correctly and the rest were at their original position, still considered?
‘Not matched’ mean the plant is in the grey area when it should not be in there (ie there is a black cube in the corresponding Soil Quality Data Area). If the team matches between 1 to 4 plants to the correct area, without placing a plant that corresponds to a black cube, then the team would be able to score the 25 points.
6. Referring to the score sheet, 6th segment ‘Remaining 5 plants touch the grey squares around their initial locations in the Seedling Area. Points are only given if at least one plant in a farm gets points’. For the at least one plant, does it consist of the green plant as well? Must it be remaining 5 plants exactly? If 4 or 6 plants, is this scoring segment considered?
All conditions have to be fulfilled. Only 5 remaining plants, and a plant in any farm, Inc. green.
WRO Tertiary (Senior)
1. During the mission setup, when the food brick is placed above the corresponding food container, is it pressed down? Or gently placed above the food container?
Please refer to page 8. The food brick is gently placed above the food container
WRO OPEN Category
<<NOTE>> Teams who are participating in this category are required to submit their report and video (via a youtube link) to email@example.com by 20th August 2018, 5.00pm.

Robotic Arm Challenge (General)
1. Only grab, suction and place action are allowed. No throwing or sliding of mission objects is allowed. Is sliding the mission object through a chute within the robot arm allowed?
Yes, it is allowed. However, the initial and final contact between the robot and the mission object has to be in a grab, suction or place action.
2. It is not stated that the robot is allowed to start the run while exceeding the robot base area, nor has the robot end the run within the base area. Therefore, can I assume the robot is allowed to exceed the area only during the run?
The robot base needs to be fully within the area at all times, during the start and finish of the run. However, the extensions of the robot arm are allowed to move out the base area during the start and do not need to be within the base area during the end of the run.
3. Rubber finish or anti-slip material can be used at the end/tip of the end effector of the robot arm. No double sided or adhesive tape, etc are allowed. Does the rule extend to allowing anti-slip material under the robot arm base?
Yes, it is allowed. The foundation structure of the robot arm base needs to be built using TETRIX, EV3 or VEX. The anti-slip material is allowed to support the robot base structure.
4. Are non-LEGO EDUCATION parts/items allowed to be part of the robot structure? As an assist to the structure of the robot?
Non-LEGO EDUCATION parts/items are allowed to supplement the structure of the robot/robot base. However, the main structure and the main components must be from LEGO EDUCATION Mindstorms EV3 set.
Robotic Arm Challenge (Advanced category)
1. Are Lego parts allowed as building components?
LEGO EDUCATION parts are allowed to support the main structure of the robot. However, the main structure and components still need to be build using TETRIX or VEX.
WeDo 2.0 Junior Challenge
1. The placement of the fruit in the grocery store and juice factory, must it be upright? Or can it be tilted?
Kindly refer to Page 7, Para 11. The fruit, upon reaching the designated areas, can be picked up by hand and place on top of the “Fruit Supporting Device”. This is to prevent the fruit from rolling away during the rest of the gameplay.
2. In the scoring sheet, what does it mean by ‘piece of fruit manually transported into the red area from the home area’?
There are two scenarios whereby the fruit can be placed at the correct designations, ie the “Juice Factory” or “Grocery Store”. The first scenario is when the robot brings the fruit from the “Farm Fields” to the “Juice Factory” or “Grocery Store” direct. The second is when the robot returns to “Home” with the fruit and then the fruit is handled and placed “manually” in the “Juice Factory” or “Grocery Store”. The sentence you quoted will refer to the latter scenario.
3. Can 2 perfect fruit be in the same grocery store? Or 1 each. Same question for ugly fruit.
There is no restriction on the above.
4. From the scoring sheet, 6th row, ‘Each fruit-supporting device (FSD) not moved completely outside the Farm Area where it was located initially. Define not moved completely.
At the end of the run, as long as the FSD is fully attached and within their own respective black box, it will be considered for scoring. Damaged FSD or FSD which are out of the black box will not be considered for scoring.
5. Is the robot allowed to collect all 4 fruits and place it on the Grocery Store and Juice Factory at the same time? Or must the fruit placement be done 1 by 1?
Both situations are allowed, either placing all 4 fruits at the same time or 1 by 1.
6. If the robot is within the Grocery Store or Juice Factory but the respective fruit is not within the area but attached to the robot. Is that particular fruit considered as within the coloured area?
The fruits itself has to be fully within the colored zones to be considered for scoring.
7. What if the fruit accidentally rolls and stops in a colored zone, will it be considered for scoring? Or must it be accompanied by a robot?
If a fruit rolls and comes to rest on the respective colored zone, it will be considered for scoring regardless if the fruit is accompanied by the robot or not.
Science Automatica (General)
1. During the tournament day, how much space will the participants have? Any materials provided?

2. Must the participants do the data logging on the spot?
Not necessary. Teams must present their data during the judging. Teams may, however, be requested to show their setup successfully collecting-downloading data.
3. Where will this presentation be held? Annex or the rooms?
The Annexe Hall
4. Is the LEGO Education EV3 Temperature sensor allowed?
5. Is the Energy Meter from the LEGO Education Renewable Energy add-on set allowed?
