FASTEST LINE FOLLOWER

23,24,25, June-2025

One of the most popular and engaging leagues in robotics competitions is the Fastest line follower League, where robots must be equipped with sensors capable of distinguishing black and white colors to navigate the track according to the competition rules. The team that completes the track with the highest precision and in the shortest time is declared the winner.

• Teams: Each team can have a maximum of five main members with no age restrictions.
• Robots : Robots must operate autonomously using microcontrollers such as STM, SRC, KRC, ARDUINO, PIC, AVR, etc.

Communication between the robot and external devices, such as laptops, Bluetooth modules, or any external systems (e.g., RF modules), is strictly prohibited.

Each robot must fit within dimensions of 25 cm x 25 cm x 25 cm, including any attachments. Robots will be tested for size compliance using a box of these exact dimensions.

Arena

• The track is made of MDF or plywood with a white base and black lines or vice versa, determining the robot's path.
• The line width is approximately 18 mm with a tolerance of ±2 mm.
• Intersections: The track may include intersections with angles no less than 45 degrees.
• Gaps: The track may have gaps with a maximum distance of 10 cm.
• Curves: The track may feature curves with a minimum radius of 10 cm.
• Angles: The track may include angled lines with external angle of up to 110 degrees.
• Loops: The track may contain one or more closed loops as follows:
• Color Reversal: In some sections, the black and white colors of the track may be reversed. Teams should note that before entering such a section, there will be at least a 5 cm straight path.
• Line Width Variation: The width of the path may vary, increasing up to 2.5 cm on each side.
• End of Track: At the end of the track, there is a completely black zone measuring 45 cm x 45 cm where the robot must stop.
• Parallel Lines: Parallel lines on the track must have a minimum distance of 10 cm between them.
