LINE FOLLOWING ROBOTIC VEHICLE USING MICROCONTROLLER
ABSTRACT
The project is designed to develop a robotic vehicle
that follows a specific path. This project uses a microcontroller of 8051
family for its operation. A pair of photo sensors comprising IR transmitter and
photo diode is interfaced to the controller to detect the specified path for
its movement.
Line follower robot is a useful
robot that is used in ware houses, industries,
and stores etc, where it follows a dedicated path. This proposed system
of a line following robot fulfils the desired functionality and demonstrates
the working of it. It uses a pair of photo sensors, comprising of one IR
transmitter and a photo diode in each. It guides the robot to follow a
specified path by giving appropriate signal to the microcontroller. Two DC
motors are used interfaced to the microcontroller through a motor driver IC.
Input signals given to the microcontroller from the sensors and then the
controller takes the appropriate action according to the program written in it
and drives motors as desired.
Further
the project can be enhanced by adding more advanced sensors to it. This will
add more features to the existing project. For example, we can use ultrasonic
sensors for detect any obstacle in front of the robot and to take appropriate
action.
