Wireless Remote Control of Omni Wheels RC Car Using Bluetooth

In this paper, we study wireless remote control of a RC car with omnidirectional wheels using
a Bluetooth application in Android-based smartphones. The RC car is developed with the Arduino board and the Android smartphone is employed to operate it. In order to operate, the RC car and the smart phone communicate with each other through Bluetooth protocol. We also use the button touch user interface (UI) in the smartphone application to control the RC car. The battery supplies power to the Arduino board, and it supplies the DC motor with an additional power. The smartphone transmits commands to be controlled in the master mode in conjunction with the Bluetooth module, and the Bluetooth module receives the data from the smartphone in the slave mode and transfers the data to the Arduino board. The Arduino board processes the received command and transmits the signal to the motor and sensors. Through the analyzed signals, Arduino's digital input and output (I/O) pins yield high and low signals and apply signals to the motor driver.
