"not moved or damaged" in the scoring table means: at the end of the run the barrier/fence is in the starting position

Explanation:
In WRO it is always the end-situation that is scored. This means that the robot can lift or move any barrier or fence during the run and then put it back.

"There is one solar cell that should be placed on the robot at the start of the run."

What does this mean?

  • The team can choose how the robot brings the solar cell to the correct area.
  • They can put the cell on the robot, under the robot, in front of the robot or in any other position touching the robot.
  • They can even put the cell inside of the robot, but only if this does not delay the starting process.
    Meaning: During the start process they cannot remove pieces of LEGO from their robot, put the panel in and then put the pieces back.
  • The team cannot touch the solar cell anymore after the start.
  • Whatever option they choose: the solar cell cannot stick out of the start area.
    Meaning the projection of the cell and the robot need to be inside the start area.

Unfortunately there is an error in the calculation of one of the examples. This can lead to confusion.

An Energy Unit is completely in the house or storage battery if it only touches the area (= the field).

Units that are on top of another unit, or that are in any way supported by another unit or the fence of the storage battery will get no points.

See the corrected example for the house. (24 instead of 44 points.) And the extra example added. (Only points for the yellow unit in this case.)

To avoid further confusion:
"only touching" refers to how the unit is supported.
It is OK if units that are fully supported by the field are just touching each other because they are next to each other.

 

The wind turbine could have fallen over during the run (is on its side) but still be only touching the relevant area.

In this case the wind turbine would count as 'not moved or damaged', because not moved in WRO means that it is still inside the designated area in the end situation.

The team is lucky and will get the bonus points.

Rule 8.9 for Football can cause some confusion, because it specifically mentions omni wheels.
It was written this way because almost all robot designs use omni wheels. But the intention of the rule is that each robot can have a maximum of three driven wheels in total.

Therefore the rule should be read as follows:

8.9 A maximum of three driven wheels - built of only LEGO branded components - can be used on a single robot. Use of a reciprocating kicker in the remaining EV3 output port is strongly recommended.

This means that the wheel cannot be devided over both sides of the motor.

See image for clarification.
