ABSTRACT
The remote control of a moving vehicle is a project that uses a radio frequency to
control the maneuver and movement of the model car. The Peripheral Integration
Controller (PIC) 16F877A is used in this project. The LCD is placed at the remote
control to help user to determine the maneuver angle of the model car. The
potentiometer is used as a joystick for the transmitter. There are 2 potentiometer used in
this project. The first potentiometer is used to control the maneuver angle and the other
one is used to control the movement of the car. The stepper motor is used instead of DC
motor to maneuver the car. This is because the stepper motor is more precise than DC
motor. DC motor is used to for the movement of the car. The stepper motor and DC
motor are interface with PIC on receiver board. The frequency of RF module that used is
343MHz. The car will maneuver to the left or right with the exact angle and the angle is
already program in PIC. The angle that has been program in the PIC is 5°, 15° and 45°.
To ensure the maneuver more precise, the movement of the motor will stop whenever
the car is maneuvering to the left or right. The head light will automatically ON when
the car detect the surrounding a little bit darker than usual. The bottom light of the car
will automatically ON whenever the surrounding is completely dark. There are also 2
other head light that can be ON using the remote control
INTRODUCTION
1.1 Overview
Nowadays, we often heard about nature disaster and how it can kill thousands of
people. For an example, sometimes when a building collapsed, there are still survivors
under the ruin but we can’t enter and search for the survivors under the ruin because it
is too dangerous and sometimes there is just a small opening. Besides that, sometimes
it is dangerous to enter dark area bluntly. We can get hurt or worst we can die because
we enter without knowing what is beyond it.
Realizing this problem, this project is developed to help us scout the
surrounding inside a dangerous area and unreachable to human. We can control the
movement of the vehicle using a joystick. The vehicle can be control within a range of 7
meter. When entering a dark place, the vehicle will automatically switch on the vehicle
light to make the vision clearer. A camera is attached to the vehicle to help us see the
visual inside the area.
In the first phase, this project will only focus on making the vehicle movement
according to the joystick and move within the range of 7 meter. After the first phase is
successfully done, the vehicle will be added with a vehicle light that will automatically
on when entering a dark area. After finish adding the vehicle light, a camera will be
attached to the vehicle and connected to a laptop or a computer.
1.2 Problem Statement
There is some areas that can not be entered by human being such as a small hole
and a place that dangerous to human. This project is developed to help human scout the
surrounding inside a dangerous area and unreachable to human.
1.3 Objective
The main objective of this project is to build a device that can control a vehicle
maneuver and movement within a range of 7 meter.
1.4 Scope
This project is focused to design and build the model of a remote control and a
model car that would be used to scout the dangerous and unreachable areas to human.
Therefore, this model will cover the scope as followed:
(i) The vehicle can be control in a range of 7 meter.
(ii) The vehicle can move forward, reverse, left and right.
(iii) The degree movement of the vehicle can be control precisely.
