The line tracking robot build by Arduino board and accessory example motor module, motor, sensor, and so on. Robot will practice mission by ordered from Arduino code. The robot can finish the mission tracking back line, crash box, move to goal and the robot be effective in practice the mission. The line tracking robot is auto robot so the From the track to create a robot by successor information and equipment, such as motors and other sensors, the robot divers to perform their duties by command from the programming. The robot can obligations to finish the task. The robot will move to the goal and powerful robots to perform tasks and automatic robot is a robot mission to make hope this robot will be useful in the future, less.
