IMPLEMENTATION OF MICROCONTROLLER TO THE CONTROL OF AN AGV

This work describes the designing and the implementation of microcontroller
to the control of an AGV. AGV is an acronym for Automatic Guided Vehicle and it's
apparently become more demanding nowadays especially in the manufacturing
industry due to its ability to self guided the transportation process. The main hardware
components consist of the microcontroller board, the sensor, the voltage regulator and
the motor driver circuits. The task of interfacing the hardware and the programming
of the software is challenging. The microcontroller will act as brain of the AGV to
control the action that should be taken by the AGV while moving under pre-defined
pathways. Basically, the sensors which are located at the front and both sides of the
AGV will sense the existence of black line at the bottom of the AGV. The sensor
provides the input signal to the microcontroller. The microcontroller will process the
input obtained and provide the appropriate instruction to the output to control the
motion of two motors. The output would results in the AGV to change the direction
of movement either to the right or left or may remain in the same direction depending
on the microcontroller' s decision. Several experiments and tests also have been
conducted to verify the operation of the circuits. The AGV prototype is successfully
designed, assembled, built and tested.
