ABSTRACT

The line following is a classic introductory robot design and requires minimal amount of resources. This robot uses Microcontroller control. This robot is intended to showcase basic sensor design and robot control system in the form of a small autonomous robot which can follow a black line over white surface.

            A proposal for a line following robots and their relevance to engineering and society is given.  A project design for a line following robot is presented and discussed.  The project description is given, as well as the project approach, experiments to be run, and a proposed schedule for completing the robot.

The vehicle is supposed to have a low-resolution sensors and actuator. The control requirement, however, is specified so as to keep the vehicle as close as possible to the center of the line. The controllability issues are investigated, A multiple IR sensor based control algorithm is investigated for straight as well as curved paths. Experimental result is shown to demonstrate the usefulness of our idea. The power for the robot is derived from the standard power supply or optionally from 12V battery.
