Abstract:
This system is mainly highlighted on the
microcontroller based on automatic line following
system. In the last few years, there has been a lot
of interest in the area of automatic operations.
This is partly due to the fact that the computer
equipments have been closer with human and
human-machine interaction has been required in
many applications, e.g. health care for the elderly,
domestic robot, entertainment, agriculture, etc.
Therefore it is necessary to establish an automatic
control system without cooperate with human.
Among the various PID control system, tuning
method is not only to control and but also to
adjust its control parameters to get the desired
control response. So, this tuning method is
suitable for automatic system. Nowadays, our
environment needs the auto-driving system in
order to get the good transportation. This paper
describes the method of how to control the autodrive
system used in car, how to control the DC
motor speed control and how to demonstrate the
some features of auto-drive system.
We propose a control system to cooperate with
human based on PID instructions. The object (car)
will move along the lane and it can test the
environment conditions in order to change
object’s position. At least 2 LDRs sensors will be
used in tested to test the path line and environment
condition.PIC 16F84A is used as an interface
between the controller (PID) and electric
circuit.PIC Basic Pro programming is used for
designing the PIC circuit.
