Line Following Robot

About the Competition

The Line Following Robot competition at CosmoCon’25 is a test of precision, control, and smart design. Teams must build an autonomous robot capable of accurately following a black line on a white track while handling curves, intersections, and sudden turns.

This event focuses on real engineering — proper sensor placement, efficient control logic, and reliable hardware matter just as much as speed. Once the run begins, the robot is on its own.

Event Information

Technical Requirements

• Maximum robot dimensions: 12 × 12 inches.
• Maximum robot weight: 1 kg.
• The robot must be powered by onboard batteries only.
• Maximum allowed operating voltage is 12V.
• No external power supply or wired connection is permitted.
• A microcontroller is mandatory (Arduino, STM32, ESP, etc.).
• IR or line sensors must be used (maximum 8 sensors allowed).
• Any motor driver is allowed.
• Any custom or commercial chassis may be used.
• Pre-built or plug-and-play circuits are not allowed; all circuits must be assembled by the team.

Competition Rules

• Each team may consist of up to 3 members.
• Only one robot is allowed per team.
• The robot must operate fully autonomously once the run starts.
• No manual intervention is allowed during the run.
• Use of wireless or remote control (Bluetooth, Wi-Fi, RF, etc.) is strictly prohibited.
• The robot must follow a black line on a white surface.
• The track may include curves, sharp turns, T-junctions, intersections, and straight paths.
• Start and finish zones will be clearly marked.
• Checkpoints may be used for scoring and restart purposes.
• Robots damaging the track, arena, or other robots will be disqualified.
• Any form of misconduct, unsafe behavior, or unfair play will result in disqualification.
