Nomy-Lella, Act 3

Born in November 2022, this robot participates in the "Rescue Maze" category of the Robocup Junior contest.
In this contest, the robot must, without any help, find its path through a whole maze. In this maze, there are "victims" that our robot must "rescue". These victims are marked by colours or letters on walls.
When the robot detects a victim, it must deposit the corresponding number of "rescue kits" next to it. The robot must indeed carry a kit distributor.

The group is composed of six girls:

  • Noémie, captain, lead programmer
  • Emelyne, co-captain, lead mechanic
  • Elena, programmer
  • Lana, mechanic
  • Léonie, mechanic
  • Manon, helper

This robot find its way through the maze thanks to its ultrasounds sensors which indicate whether the robot is next to a wall or not.
The robot uses the wall follower algorithm which states that, to find the exit of a maze, we have to follow a wall continuously. So, this robot actually follows the wall to its left. If there's no wall to its left, it turns to the left until there's one. If there's one wall to the left and in front of it, it turns to the right.
The robot has a color sensor that detects the wall's color. If the wall is green, it ignores it. If it's yellow or red, it deposits one "rescue kit".
It must also read letters on walls. We are still setting this up. The robot will be equipped with a Rapsberry Pi 4B which will control a second "kit" distributor.
If the letter is a U, it ignores it. If it's a S, it deposits one "rescue kit". If it's a H, it deposits three kits. -> The robot's letter detection is made by a python script using "OCR" (Optical Character Recognition).
Finally, the robot has a color sensor under it, as it must avoid black tiles and pause for 5 seconds on blue tiles.

Sweet Bubble Tea'm

The group meets twice per week: On mondays noon and on tuesdays noon.
It allows us to work on the robot two hours per week.
We also did tasks at home, such as coding or printing 3D parts.
Our beginnings were disastrous, as we lost a lot of time. Two weeks before the contest, the robot couldn't move!
But, we finally managed to win this contest (our trophy is the red one).

May update, we won the national contest! We are France champions!
July update, we finished 15th in the world contest! It was tough, but we managed to be in the middle of the rankings.
