CEBELÜ's robot
The CEBELÜ team

In their words

We are team “CEBELÜ” attending RoboCupJunior Rescue Maze from Türkiye. The name of our robot is “Ayla-890” in memory of the Turk martyrs of the Korean War. We will use this name when referring to the robot in later parts of this document.

We figured that for us to navigate throughout the maze with maximum efficiency and speed, we must have a small, compact and agile robot. So we fit all of our hardware into a 132x175mm chassis, therefore Ayla-890 has a total size including tires, reskit mechanism etc. 170x190mm. Combined with a maximum speed of 2,5 tile/s (75 cm/s) Ayla-890 is decent in turns. Moreover, because we encounter sharp turns very often in the maze, this sets us apart from other competitors and saves a lot of time.

After extensive research, we have decided that none of the commercially available wheels met our requirements within our budget. Therefore we decided to cast our own specially designed tires out of 30 ShoreA RTV silicon. This allows us to have a higher road grip and overcome obstacles more easily.

We used 3 cameras on the sides and front to identify victims and a custom designed 3D printed system to deliver kits to both sides of our robot with high accuracy. For aligning the robot, navigating through the maze, detecting ramps and obstacles, we used a total of 8 Time of Flight (ToF) sensors placed; 4 on sides and 2 in front dedicated for ramp detection and better alignment, 2 looking diagonally in front of the vehicle specifically designed and trigonomically calculated for obstacle detection and also used for validation of ramp identification. We also used IMU for more reliable alignment and movement.

Rather than relying on complex path-planning algorithms, Ayla-890 utilizes a lightweight sensor-driven right-hand wall following navigation strategy, enabling fast and reliable exploration of unknown maze environments.

ToF Sensors (8x) (Purple): Four side-mounted, two front-facing, and two
diagonal ToF sensors are used for wall following, maze navigation, robot
alignment, ramp detection, and obstacle detection. The diagonal sensors were
positioned using trigonometric calculations to improve obstacle recognition and
validate ramp identification.

IMU: Provides orientation and motion data, enabling more reliable alignment,
precise turns, and stable movement on ramps.

Victim Cameras (Left & Right) (Black): Used to detect victims on both sides of
the maze and determine the correct side for rescue kit delivery.

Color Sensor: Used to detect floor colors such as black tiles and other field
markings.

Encoders: Measure wheel rotation for accurate distance tracking and movement
control.

DC Gear Motors: Provide the driving force for the robot. Their speed and
direction are controlled precisely to ensure smooth navigation, accurate turns, and
reliable movement through the maze.
