Android Application based Robotic Vehicle

Abstract

The work is designed for spying purpose using android OS device for remote operation, dangerous area like war field, disasters, area covered by terrorism, for underground tunnel surveillance etc. where human cannot enter. An 8051 microcontroller (AT89S52) is used for the desired operation. At the transmitting end using android application device, commands are sent to the receiver to control the movement of the robot either to move forward, backward and left or right etc. At the receiving end two motors are interfaced to the microcontroller where both of them are used for the movement of the robot. Remote operation is achieved by any smart-phone/Tablet etc., with Android OS, upon a GUI (Graphical User Interface) based touch screen operation. The android application device transmitter acts as a remote control that has the advantage of adequate range, while the receiver have Bluetooth device fed to the microcontroller to drive DC motors via motor driver IC for necessary work. we use Bluetooth communication to interface controller and androidThe whole operation is controlled by a AT89S52 microcontroller. A motor driver IC is interfaced to the microcontroller through which the controller drives the motors.
