Line Following with Proportional Control in EV3-G

Getting a mobile robot to follow a line smoothly and quickly is the foundation of competitive robotics, yet many beginners struggle with jerky, unreliable movements. Moving beyond simple on/off switches to advanced algorithms is the key to winning races and completing challenges. This written course guides you through the principles of proportional control (P-regulator) using two light sensors in the EV3-G programming environment. You will transition from basic logic to smooth, self-correcting movement algorithms that make your robot highly competitive. What you'll learn: - Understand the core math and logic behind proportional control systems. - Configure and calibrate two light sensors in EV3-G for maximum accuracy under varying lighting conditions. - Calculate error values and apply proportional coefficients to adjust motor speeds dynamically. - Build clean, efficient EV3-G program blocks that implement the line-following algorithm. - Troubleshoot common movement errors, oscillations, and track-loss issues through systematic testing. The course begins with foundational concepts of sensor feedback and error calculation before walking you step-by-step through writing the EV3-G program. You will learn how to fine-tune your coefficients using logical troubleshooting methods. This course is designed for beginner roboticists, students, and educators looking to master competitive robotics algorithms. No prior experience with proportional control is required.
