In war zone, human causalities are more due to physical engagement of soldiers with the enemy, especially in mountainous terrain, the ratio is approximately 1:10. So it is better to engage or sacrifice machine instead of our soldiers because human sacrifice brings sorrow to the country and family suffers lifelong, so it is better to engage or sacrifice machine instead of our soldiers because human sacrifice brings sorrow to the country and family suffers lifelong. It will be the added gadget to armed forces to carry out work easily. Many of the soldiers die and the whole family suffers for decade so with this project the army combat will be less and only robot carry out operation to destroy them. If by chance our robot is detected, the emergency button is pressed and the robot destroy itself causing explosion in that area.

Step 1: What We Doing
This paper describes the development of robot which can travel on terrains detecting obstacle controlled wireless. by PC with communication through RF Transmitter and Receiver pair. The motor direction can be controller using H bridge module. The robot has a metal detector circuit to detect mines and retrieve data to us. A wireless camera is mounted on top and used for surveillance and recording purpose. A system to drop bomb at enemy site is designed and operated wireless. Arduino is the brain of the whole system which control all other subsystem interfaced with it.
Step 2: Design of Chassis
The chassis we are using is Tamiya type with rubber belts. Chassis is made up of acrylic material, light and tough Dimensions of chassis is 14” *6”. Motor used for driving purpose is high torque DC motor (10kg/cm),12V,1.4A. The interface of robot is done with Arduino UNO microcontroller. UV sensor is placed in front of the robot to judge the distance. H bridge module is used for controlling the direction of motor. Relay module is used for bomb displacement purpose at enemy site.
Step 3: BLOCK DIAGRAM
The various components of block diagram are: -
UGV Block:See picture
1) UGV Microcontroller – The microcontroller used to control UGV is Arduino Uno which is 5V, 8-bit controller which can be interfaced with many other devices. 2) Power Supply – 9V DC battery is used as the power supply to power Arduino, Wireless Camera and Relay Module. 3) Mine Detection circuit – Mine detection circuit is mounted on UGV which helps to detect mines in its path. 4) H Bridge Motor Driver – This motor driver is used to control the direction of DC motor and help it change the movement of UGV. 5) Ultrasonic Sensor – The sensor is used to measure the distance of the obstacle and act accordingly. 6) Wireless A/V Camera – Wireless camera is mounted on top of UGV for surveillance and recording purpose. 7) Explosive Handler – A small DC motor with gear is mounted on UGV which trips when signal is given through transmitter to drop an explosive at any moment. 8) RF Receiver – This is the communication channel between the UGV and transmission station which receive signal given by transmitter and respective functions takes place accordingly. 9) DC Motor – Two DC motor helps to push the UGV which is connected to H bridge to drive it in any direction.
PC Block:See pic
The various components of the block diagram are: -
1) TV Tuner Card – It allow TV signal to be received by PC. 2) Wireless Video Reception – The receiver receives the video signal from the camera and send it to PC through TV tuner. 3) RF Transmitter – This helps to transmit RF signal to receiver on UGV and sends command given by PC. 4) Remote PC – The PC keyboard is used to control the direction of motor, explosive handler and record Video signal through TV tuner.
Step 4: Flow Chart:Gives Rough About How to Code It.
Step 5: COMPONENTS REQUIRED
Ultra Sonic Sensor
Surveillance Camera (
H bridge driver
RF module(Rx & Tx)
We need 2 Arduino(1 for UGV and other for transmission station)
