The ‘Embedded Based Metal Detector Robotic Vehicle’ is used to detect metal and ores beneath the soil remotely.
With embedded system, robotics is usually one of the closed linked topic as circuit, power requirement, portability minimizes to its limit.
Metal detection is done at specified location, as at entry point of any premises, stadium, railway station, bus stands. In such cases no moving robot is needed.
Where as, ore detection under soil or to detect landmine is done with moving [metal detecting robotic] vehicle. Usually such robots are controlled wireless or using Radio Frequency Technology. No man/dog can be posted for such works as the work is hazardous or lethal in nature.
Objective: A moving robotic vehicle detects while moving as per user commands and found any metal stops and makes alarm sound.
A robot moves in the intended area, as user send commands through his RF Transmitter unit. If any metal/landmine is detected under robots hood, it stops their and makes alarm sound for user attention. Such robot is fitted with Metal Detector, Alarm unit and RF Receiver at suitable place. Robotic vehicle has its own power bank to meets it power supply for movement, receive commands, metal detection and alarm sound.
Learning curve:
The System is built around 8051 Microcontroller. The code does all the controlling part of the system.
The Vehicle moves as per user commands. The Command transmission is done using Radio Frequency Transmitter/Receiver. So range is decided by this module.
The Microcontroller chip is used to do controlling, accepting metal detection information and driving alarm using its memory resident code/program.
The Metal Detector module is used to detect landmine/metal parts and is fitted properly below the robot.
The Alarm unit is nothing but a buzzer, and driven directly by microcontroller chip when metal is detected at its input pin.
The Robotic part is constructed using popular H-bridge IC and driven logically by Microcontroller code. As user sends commands from remote end robot moves in Forward or Reverse direction and Turns Left or Right.
The power supply unit gives all necessary power to robot for smooth operation.
Note that the controlling range of the robot is limited by RF Transmitter, Receiver modules used in the system.
Applications:
- Such system/project can be used to detect landmines, metal, minerals/ores, bombs, steel bars in concrete, weapons in airport, buildings etc.
- Since a system is wireless and embedded in nature, it is very easy to deploy, portable to carry and maintains cost is minimized.
