Hello
I have a question about “Successful Stair Navigation”.
In Rescue Maze Rules 2024
4.6.9 Successful navigation means the robot moves from the bottom tile on one side of the stairs to the top tile and then onto the bottom tile on the other side of the stairs without assistance.
Please tell me in what state it becomes “Successful Stair Navigation”
Best Regards
MASA
Interesting question. Maybe “B”? Will wait the answer from the staff.
Hi @MASA
Based on the new, 2025 draft rules:
5.6/9. Successful Stair Navigation. A robot is awarded 5 points for navigating up or down the stairs (i.e., the robot can score a maximum of 5 points per direction (up or down)). Successful navigation means the robot moves from the bottom tile on one side of the stairs to the top tile (or vice-versa) and is entirely within the horizontal tile without toppling over.
Because the rules say, “entirely within the horizontal tile”, point is awarded from option “C” onwards.
Thank you @PeterParker!

Hello @CsabaAbanJr
Thank you for your answer.
I have more questions.
I read the Rescue Maze 2025 Rules DRAFT.
Rescue Maze 2025 Rules DRAFT
5.6.9. Successful navigation means the robot moves from the bottom tile on one side of the stairs to the top tile (or vice-versa) and is entirely within the horizontal tile without toppling over.
If the robot moves from a1 to a2, it will earn 5 points for successfully navigating the stairs. Additionally, if the robot moves from a2 to a3, it will earn another 5 points for successfully navigating the stairs, bringing the total to 10 points.
Although the staircase has fewer steps, if the robot moves from b1 to b3, it will earn 10 points.
Rescue Maze 2025 Rules DRAFT
3.4.6 The length of the top of the stairs is at least 15 cm.
Even if the robot moves from c1 to c2, it will not earn points for the stairs (because the robot has not fully entered the top tile). If the robot then moves to c3, will it earn points for the stairs? (5 points ?)
and more one
If the small robot moves from d1 to d2, it will earn 5 points for successfully navigating the stairs (because the robot has fully entered the top tile). Additionally, if the robot moves from d2 to d3, it will earn another 5 points for successfully navigating the stairs, bringing the total to 10 points.
Is this correct?

Very nice argumentation, as usual!
Reading between the lines, the last scheme (d1,d2,d3) demonstrates that the rules are becoming so complex we need well-trained referees.
Hello @CsabaAbanJr
Since the Rescue Maze 2025 Rules have been released, I will ask my question about the stairs again.
Rescue Maze 2025 Rules
5.6.9. Successful Stair Navigation. A robot is awarded 10 points for navigating up or down the stairs (i.e., the robot can score a maximum of 10 points per direction (up or down) ). Successful navigation means the robot moves from the bottom to the top of the stairs (or vice-versa) and is horizontal.
Please tell me in what state it becomes “Successful Stair Navigation”
( I think B )

Hi @MASA!
You are right, according to the new rules, from situation “B” onwards, the point is awarded because the robot has reached the bottom of the stairs and is in a horizontal position. It is no longer a requirement for the robot to completely leave the stairs.

Hi,
I need clarification on the scoring: “A robot is awarded 10 points (i.e., the robot can score a maximum of 10 points for navigating up or down the stairs, points per direction (up or down)).”
Does this mean the robot can earn 10 points for going up and an additional 10 points for going down on the same set of stairs, for a total of 20 points if both directions are successfully completed?
Yes, this year it’s possible to earn 20 points for the stairs, 10 points when the robot goes up the stairs and reaches a horizontal position, and another 10 points when the robot comes down the stairs and reaches a horizontal position.

I would like to clarify my previous response, as it wasn’t entirely accurate in relation to your question.
In terms of scoring, the robot can earn 10 points for each set of stairs, regardless of the direction from which it first crosses it.
The commonly used “hill-shaped” stairs are considered two separate sets of stairs, since they consist of two parts (up and down). Therefore, when the robot crosses them, it can earn a total of 10 + 10 = 20 points.
However, a stair used as a ramp only consists of a single up or down section, so the robot can earn 10 points for it.
For example:
Here is a diagram to visualize:

Thank you for the very detailed clarification. The misunderstanding came from the “points per direction” part, as it seemed that the same set of stairs could be awarded twice — once when going up and once when going down. But your diagram clearly shows that points are only awarded on the first traversal.
