Introduction• Bluetooth controlled android car consists of a cooperative

subsystems that rely on and Control another subsystem.

• The subsystems are divided into two main systems, the car and the remote control.

Objectives• Controlling robot car using smart phone.• Design a system performs specific functions.• Develop android application .• Dealing with sensor interface with microcontroller• Dealing with module interface with microcontroller

General description• The final design will consist of vehicle and remote control,

The PIC will be our central processing unit . 

• The vehicle and the remote control rely on communication from one device to the other to produce a functioning system.

• The system is expected to allow user to simultaneously connect to vehicle through Bluetooth pairing between the android device and the Bluetooth chip on the vehicle and control the motion of the car.

• PIC 18f4550• Power source• Regulator• led• 2 DC motor • L293 motor drive • Car vehicle• toothpick 2.1 Bluetooth module• Android device • LOGO vibration sensor

Components

Software tools• c language to program the PIC microcontroller using

MikroC PRO for PIC – C complier for microchip

• java language to develop the mobile application using ADT (Android Developer Tools) which is a plugin for Eclipse that provides a suite of tools that are integrated with the Eclipse IDE.

Problems

• car front wheels has a balance problem , one of the wheels is higher than the other.

• Android application is slow and stop working so we need to restart the application

Future work

• Using Wi-Fi technology instead of Bluetooth technology.

• Add the accelerometer option to control the car

Conclusion• We were able to complete our project and produced a

Bluetooth controlled android car that can be controlled through a smart phone.• This opens door for wide range of possible similar

applications.1) Assistant for professor .2) Assistant for housewife .3) Electrically powered wheelchair
