I have been on the training team for two years in the METU Robotics Community, which I have been participating in for three years. The aim of the training team is to provide the new members of the community with the necessary training in software, mechanics and electronics. For this training, we first create a 6 or 4 week plan and divide the topics into weeks. We want them to work on their own with certain documents and assignments. Of course, they can ask us their questions whenever they want. At the end of the entire training, we organize a workshop. In this workshop, we have been making line follower robots for new members for two years.
In these workshops, we used Arduino, QTR sensor, Motor driver, a pair of motors and a pair of wheels to create the line follower robot. Thanks to the QTR sensor, we get information about the position of the line. The 8 phototransistors on the QTR transmit the color information of the area under the robot to us analogously. According to this information, we enable the motor on the right or left to slow down and give direction to the robot. You can review the code we used below:
