Height Restrictions

Dear Friends,

our team is a bit confused about the definition of H_top, mainly about two points:

  1. The rules state, that the robot is measured in an upwards standing position with legs fully extended and the head “tilted to either its maximum upwards tilt angle or the horizon line, whichever is lower.” However, the referee training video shows the robot lying on a plank with the head looking straight forward, regardless of which orientation would be lower. Which of these variants will be used at the world championship?

  2. What exactly does “maximum upwards tilt angle” and “horizon line” mean? We assumed, it means that the robot either looks towards the ceiling as far as possible, or straight towards the horizon, whichever of these two results in a smaller H_top. Is this assumption correct?

Thank you for clearing up the situation,

with kind regards,

Hi Sebastian,

  1. During the robot inspection, the measurement is usually taken with the robot laying down on the measuring board. Since the rules specify that the robot is supposed to be standing with the legs fully extended, the length of the standing or laying robot should be the same. Since the robot laying down does not require the robot to be turned on, this method makes it easier for the committee to measure.

  2. For almost all robots this means the horizon line. Only in case the robot is physically not capable to tilt the head to the horizon line, the maximum upward tilt is taken.

Let me know if you have any other question.
Cheers,
Maike
