A line-following robot is an autonomous mobile robot that uses infrared (IR) sensors to detect a high-contrast path (typically black on white). The sensor data is processed by a microcontroller (e.g., Arduino, ESP32), which executes a PID or conditional control algorithm to adjust the PWM signals sent to the DC or servo motors, enabling the robot to follow the predefined line accurately. # #electrician #follower #electronics #facebookreelsviral ##robotics | Electronics & Electricals
