The general rules state that no data input into the robot is allowed after team handed it in (Rule 6). The aim of this rule is to change the randomization after the robot has been handed it, so no hard-coded solution are used to solve the task.
In the online international final, this rule is interpreted as follows: No hard-coded solutions are allowed. It must be clearly visible in the uploaded video, that the robot uses its sensors to solve the randomized task.
In lack of clarity, a head judge will contact the team separately for a specific presentation of the code and the robot. Non-compliance to this interpretation results in deduction of points or disqualification.
Following the rules some part of the randomization are valid for the whole competition day (Elementary: position of barriers; Junior: position of parked cars). These elements will have the same position in all 5 randomizations for the international final and can be hard coded into the robots. There is no need to detect these objects via sensor.
