Abstract: In the existing line follower robot, the robot operates as the name specifies. It is programmed to run on a black path on a white area and detects the turns and deviations and changes its movement appropriately. Arrays of IR sensors are used for detecting the path. Proposed project designed to work similar to line tracking robot. With slight modification, that reduces the complexity. By eliminating path, background and sensors we have reduced the complexity present in the existing system. RF technology is used in this project that helps in transferring the path drawn on the computer screen for the movement of Robot. The window to draw the line on computer screen is developed using C# language. And for tracing the path, we have used line algorithm which is aim of this project are used. And the robot is developed by using embedded application. H-bridge circuit is used to control the speed of the robot. Motor is used for the turning movement of Robot. From the computer, the path is transmitted and sensed by microcontroller. For turning of robot, differential steering is used. For each front and back wheel motors are used to rotate along the path. For controlling the two DC motors to navigate through its path, microcontroller is used. The mechanical constructional design and circuitry interfacing with microcontroller of robot has to be presented in this project along with computer side programming.
