Navigation is the significant feature in applications of Mobile Robots. Various navigation tools are available based on accuracy & complexity. PID Controller is used for designing a Line follower Robot. Array of multiple sensors detects the black surface and travel along the line. Arduino Uno continuously monitors the signal from the sensors and turns the Robot as the line getting detected. Obstacle detection is performed by Ultrasonic sensor. Line follower Robots are applicable in military, intruder alarm systems and so on.
