Every country is preparing for a strong army to prevent them from terrorists, the soldier undergo a particular period of training in the camp and finally they will be shifted to the most dangerous place of where terrorist area camp, even to protect the borderline between the two countries.
The landmine is the most dangerous weapon that is invented when the World War happened. It plays a very important role in the period of war and most of the soldiers have lost their life or body parts due to their inability to detect them.
For this, a robot can be used to find the landmine in the critical areas and also the robot can be controlled by the technologies like Zigbee, Radiofrequency, DTMF. The metal detector is used to find the landmine in the land and map them or mark in the field exactly. Then they can be easily defused with the help of robot.
You need the controller as 8051, metal detector, motor drive, transmitter and receiver to control the robot direction. When landmine is detected make them as the mark like from robot place some centimeter the Land Mine is located.
In addition, the robot with the camera can be used to surveillance as like the drone.
AT89S52: The AT89S52 is a low power, high performance CMOS 8-bit microcontroller with 8k bytes of in-system programmable flash memory. This is a powerful microcontroller which provides high flexibility and cost-effective solution to many embedded control applications. It has the following standard features: 8K bytes of flash, 256 bytes of RAM, 32 I/O lines, watchdog timer, 2 data pointers, 3 16-bit timers/counters, on-chip oscillator and clock circuitry.
L293D: The L293D are quadruple high-current half drivers. It is designed to provide bidirectional drive currents of up to 600-MA at the voltage ranging from 4.5V to 36V. It is mainly used to drive inductive loads such as relays, solenoids, dc and bipolar stepping motors. On the L293D, external high-speed output clamp diodes should be used for inductive transient suppression.
DC Motor: This is an electric machines which converts electrical energy to mechanical energy. This is the most commonly used motor for the actuation of robots.
Zigbee: The robot uses Zigbee to establish the connection. It works on 2.4GHz ISM band with 20~250kbits/s data rate and has a transmission range of up to 1.5 km.
The Robot model should made and the fix the metal detector to small length of post to hold it.
Attcah the input to the Micro Controller and you need to program concept of the program.
If the landmine is detected the excalt location can mark
Fix the zigbee or RF receiver on the robot and the transmitter to control the robot direction.
You can add the Camera to live using wireless communication
Project Brief: The control unit transmits the command using Zigbee, which is received by the Zigbee receiver unit in the robot. The survey robot then moves according to the instructions received. A buzzer sounds when its detects landmine. The geared DC motor is used for actuation and is controlled by the L293D motor driver. A 12V battery or a 12V adapter is used to power up the entire robotic system.
