Abstract
Robot Car is a System designed for robot controlling implemented with many features, and is a robot that can be controlled via Smartphone. This system uses microcontroller interfaced with different modules such as Wifly module and Bluetooth module and DC motors and different sensors to detect obstacles and the movement of objects. When anyone wants to use this robot all he can do is to have smart phone (Android device) that connect to Bluetooth then Bluetooth module will send the data serially to the microcontroller and the controller will send the command to motor to rotate and control the robot, this enable users to control their robot from distance up to 100 meter and user can read the status of the robot on their app when they send the command to the robot car.
