Design of Metal Detecting Robot

Abstract

In the current period robots play an important role. The purpose of this project is to design a military robot that will detect the enemy. A robot is controlled through Android Application using a Bluetooth module. To detect the status of the robot, the hardware Arduino UNO microcontroller board is used. This microcontroller will sense and control the object. Arduino is very easy to use, and the program is erasable and allows reprogramming from which multifunctional applications can be designed in a robot. Arduino UNO is interfaced with Bluetooth module through UART protocol. An ultrasonic sensor is employed to detect the space of the thing. For example, Bluetooth, Wi-fi and ZigBee innovation to control other gadgets with the help of improved of present-day innovation and Android Smartphone. Bluetooth innovation means to trade information remotely over a short distance utilizing radio wave transmission including highlights to make straightforwardness, insight, and controllability. In this paper we have planned a robot that can be controlled utilizing an application running on an android smartphone, it sends control by means of Bluetooth which is interfaced to the regulator. The regulator can be interfaced to the Bluetooth module however UART convention and shows movements as per the commands received by android application.

Existing System

The existing system consists of transmitter and receiver circuit. The transmitter circuit transmits the commands required to operate the robot. The receiver circuit receives these commands through RF and moves the robot according to the received commands. A metal detector is interfaced to the controller in the receiver side. Thus whenever any metal is detected the robot stops there and buzzer starts ringing.

Proposed System

The motive of this methodology is to design a successful architecture and system of a robot that will accomplish all the design requirements. We decide to implement the advanced smartphone technology by operating the robot via Android Application. Design of Components are described as follows: Bluetooth Module- Bluetooth module HC-0 is used that will transmit the commands to a microcontroller that are received from the Android Application. Arduino UNO Board- Robot is operated by a microcontroller which is programmed with the help of software i.e. Arduino. When two devices are connected, commands are sent to the Bluetooth module and it transmits the command to the Arduino UNO microcontroller. Ultrasonic Sensor is used to detect an obstacle; the buzzer alerts the user by LED which is connected with the sensor. An Android Application on mobile phone will control the robot by giving the commands. As the mobile phone will act as a remote controller for the robot.
