LINE-X National Robotic League 2025

The LINE-X National Robotic League 2025 is a premier autonomous line-following robotics championship that challenges teams to push the limits of robotic speed, sensor calibration, control systems, and autonomous algorithm efficiency.

Held in Delhi, India, the competition brings together robotics enthusiasts and technical teams to design and build custom autonomous robots capable of navigating a demanding high-contrast track featuring broken lines, sharp curves, and intersections.

Competition Highlights

• 🤖 100% Autonomous Robots — Robots must operate without manual intervention.
• 🏁 High-Speed Line Following — Teams compete to complete the track in the shortest possible time.
• 🎯 Precision Sensor Calibration — Accurate sensor readings and control algorithms are essential for navigating difficult sections.
• ⚙️ Custom-Built Robots — Participants build their robots using modular components such as Arduino-based controllers and IR sensor arrays.
• 🧠 Autonomous Algorithms — Efficient control logic and rapid decision-making are critical to achieving competitive times.

Robot Specifications

Participants must follow the competition's technical requirements:

• Maximum robot dimensions: 25 cm × 25 cm × 15 cm
• Maximum power source: 12V DC
• Robots must be 100% autonomous
• Modular components such as Arduino and IR sensor arrays may be used.
• Pre-built commercial toy robots are not permitted.

Track & Scoring

The robot must follow a 30 mm wide black line on a white surface.

Each run has a maximum time limit of 3 minutes. Manual repositioning or touching the robot during a run results in a 5-second time penalty, with a maximum of 3 restarts per run.

Remote controls, wireless links, and external human intervention during the run are prohibited. Remote assistance can result in disqualification.

The final ranking is determined by the lowest cumulative time, calculated from the track completion time plus applicable touch penalties.

2025 Winners

The First Place title was secured by the Reyansh and Anurag Team, receiving a cash prize, medal, and trophy.

Second Place: Kavissh and Darsh
Third Place: Prakhar

Technical Judges

The competition was evaluated by a technical judging panel consisting of:

• Piyush Bafna Jain
• Mr. Manav Dugar Jain
• Arit Jain
• Shaurya Sharma
