Infrared Line Follower Robot

Project Overview

Build a robot that follows marked paths and handles gentle turns autonomously.

Objectives & Learning Outcomes

Line sensors, PID concepts, motor calibration and recovery maneuvers

Required Hardware

Arduino Nano, IR sensor array, motor driver, two motors, test track

Suggested Build Stages

1. Review the components and create a low-voltage wiring plan.
2. Assemble the prototype and test each sensor or module individually.
3. Implement firmware, display or communications in small verified steps.
4. Integrate the modules and document operating states and failures.
5. Run validation tests and prepare demonstration documentation.

Testing & Validation

Measure lap success, sharp-turn failure rates and sensitivity to lighting.

Suggested Deliverables

Working demonstration, wiring diagram, commented firmware, test observations, component list, project report outline and presentation outline.

Educational project concept. Verify circuit values, actual component compatibility and safe operating limits before assembly. Illustrations are representative, not exact build photographs.
