IntroductionBluetooth 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.

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

General descriptionThe 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.

Problemscar 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

ConclusionWe 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.Assistant for professor .Assistant for housewife .Electrically powered wheelchair, 2003-2015.
