Gearotons Line Following Robot Kit Smart Robot Assembly Project Kit Obstacle Avoidance Robot with Music DIY Kit Educational Robot Toy, Medium

The robot plays music while precisely navigating its path. Infrared sensors enable it to avoid obstacles and barriers while following a line. After getting blocked, it’ll stop, move backwards, turn back and continue following the line. Two LEDs on the ears send out a signal by changing their color when the robot sees an obstacle. If the robot is not on the line, it might run around and try to find it. The success rate depends on which moment is its lucky moment. When the robot is lost, it might keep spinning around. Putting it back on the line and restarting it will help. Tip. When placing the track on the floor, please make sure the floor is white enough. The background color of the track should be white enough, or else the sensors might not work properly.
