This document summarizes a student project to design a robot for landmine detection. It outlines the problem of landmines remaining after warfare endangering civilians. The robot uses a rocker-bogie mechanism to move over uneven ground and metal detector sensors to identify landmines, alerting operators with a buzzer. So far, students have researched these technologies and built a six-wheeled robot frame with the goal of integrating remote control, sensors, and detection systems to create an autonomous landmine detection robot.

Problem Definition
• Landmines are considered to be very deadly
and destroy weapons in warfare. These land
mines are treated to the civilians after the war
ended.
• Landmines detection is most crucial during
warfare and even after the war.
• These landmines detection robots can play a
huge role to spot the landmines in war areas by
lowering the risk of losing a human life.

Introduction
• Robots are very important. Nowadays, they are used to
operating on uneven surfaces. The rocker-bogie mechanism
enables a six-wheeled vehicle to keep all six wheels in
contact with a surface even when driving in severely uneven
environments.
• There are two advantages to this rocker bogie. The first one
is that the pressure of the wheel on the ground will be
balanced. The second one is that while traveling over
uneven surfaces, all six wheels will remain in contact with
the surface.
• Metal detector sensors are mainly used to detect metals that
are inside the objects or metal objects which are under the
ground or on the ground. It is used which helps in finding
out the landmine in a more accurate and efficient way.

Working Principle
• Movement of the robot
 For easy movement of the robot we are using the rocker-bogie mechanism
which will help the robot to move on rocky surfaces.
 We are using the “Radio Frequency Remote Controller”, which is a programmed
circuit that has the preprogrammed codes to move the left and right sides of the
motor accordingly and also individually.
• Sensing the landmine
 To sense the landmine we are using a metal detector sensor which will be
onboard on a robot connected to a microcontroller which will send a signal to the
buzzer which will intern make a buzzing sound and alert the person.

• Construction
 Building a six-wheeled robot considering a rocker-bogie mechanism so that the
robot can operate efficiently even on a rocky surface.
• Connecting RF Remote controller to the wheel
 Radio frequency remote controller is a programmed circuit to control the DC
motors so the wheel of the robot that is DC motors need to be connected to the
RF remote controller module.
• Installing a metal detecting sensor and buzzer on the robot
 Metal detector sensor needs to be installed on a robot so that it can detect a
landmine. This sensor needs to be connected with a microcontroller to receive
and send signals from the sensor to the buzzer which will activate the buzzer and
alert the person.
• Operating
 We can easily operate the robot with the help of an RF remote controller which is
basically designed/programmed to control the robot.

Work done so far
• Collection of required data to build this project
like:-
 How to build a rocker bogie mechanism
 How metal sensors works

9. Outcome of project work

As per the research, it is found that
the rocker-bogie system reduces the motion by half compared
to other suspension systems because each of the bogie's six
wheels has an independent mechanism for motion and in
which the two front and two rear wheels have individual
steering systems which allow the vehicle to turn in. A metal
detector sensor detects the metals hidden within the objects.
