The project is designed to
develop a robotic vehicle that can sense metals ahead of it on its path similar
to sensing land mines. The robot is controlled by a remote android application.
Remote operation is achieved by any smart-phone/Tablet etc., with Android OS,
upon a GUI (Graphical User Interface) based touch screen operation.It consists
of a metal detector circuit interfaced to the control unit that alarms the user
behind it about a suspected land mine ahead. An 8051 series of microcontroller
is used for the desired operation.
At the transmitting end using
android application, 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 they are
used for the movement of the vehicle.
The android application device
transmitter acts as a remote control. While the receiver end Bluetooth device
is fed to the microcontroller to drive DC motors via motor driver IC for necessary
work. A metal detector circuit is mounted on the robot body and its operation
is carried out automatically on sensing any metal underneath. As soon as the
robot senses this metal it generates an alarm sound. This is to alert the
operator of a possible metal (eg: land mine) ahead on its path. Further the
project can be enhanced by mounting a wireless camera on the robot so that the
operator can control the movement of the robot remotely by watching it on a
screen.
