1. Metal Detecting Robotic Vehicle FAIYAAZ AHMAD ID-14101048 SECTION-3

3. How a metal detector circuit works ??  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.

6. Hardware Components:  8051 microcontroller  Radio Frequency (RF) transmitter and receiver pair  RF encoder and decoder  Push buttons  Buzzer  DC Motors  Motor Driver IC

7. Software Components:  Keil software  Flash magic  Proteus.

8. Metal Detector Robot Applications:  These robots are used in detecting landmines.  Robots are used for in detecting the minerals present in the ground.  These robots are used for detecting the bombs.  These can be used in construction industry for locating steel bars present in concrete.  They are used in airports and building security to detect the weapons.

9. Limitations : The transmitter can operate the robot only in the range of RF that is approximately 30 meters.
