to mark as completed Light Line Follower Robot (Autonomus Light Path)
This robot is designed for leading people to their sits in cinema, theatre.. etc by controlling their tickets and accompanying them. It is basically a line follower robot, but its path makes it different from other standart line followers. The path is also autonomous, it is controlled by a PIC16F877A according to a ticket control system. By reading the ticket with CNY70 reflective optical sensors it decides the necessary path to the sit and define the path by lightening it. Therefore, the robot can detect and follow the white light path on the black surface to the sit and after waiting for a while beside the sit it comes back to its starting position. When the robot reachs its starting position the white line path disappears. New different ticket makes a new different path be lightened. The robot is controlled by PIC16F628A and I’ve used 5 CNY70 reflective sensors to detect the white line. There are also 4 CNY70 reflective sensor in the ticket reading box to detect the ticket’s code.
I’ve actually made this robot by affecting Wall-e movie. As you remember the robots i that movie follow also the light paths on the axium’s surfaces to find their ways in order to serve. This is also a similar principle.
