Design and implementation of multi sensor based autonomous minesweeping robot
1. Design and Implementation of Multi-sensor Based
Autonomous Minesweeping Robot
The act of removing landmines from the minefield is called mine clearance or demining
process. On the other hand mine detection is referred to minesweeping procedure. Mine
clearance term is often used for removing landmines within active combat zones. In military
applications the priority of speed is rather than exactitude. In contrast with humanitarian
purposes, exactitude of minesweeping procedure becomes more important. Minesweepers use
many tools in order to accomplish their task. Trained animals such as dogs and rats are
historically employed to find the landmines. The modern techniques of landmine detection are
relied on metal detectors or vehicles with special mechanical devices that are designed for this
application. To reduce the human activity within the minefield, all these tools and techniques are
applied. Recently autonomous robots are being developed to decrease the possible civilian mine
casualties. Minesweeping robots are classified into the rescue robots category that is recently a
hot topic in robotic science.
Existing System:
Most of the robots are too huge and heavy to carry out such tasks in some narrow areas of
city such as narrow aisles of buildings or pipelines of factories. To avoid this mini-size robot
with multi sensor is designed.
Proposed System:
Reduction of the human activities in dangerous environment is the first objective of
employing the autonomous mobile robots in many applications. Mine detection is a risky action
that can be done by either human or robot. Here we design a mini sized robot with ultrasonic
sensor, minesweeping sensor and Zigbee wireless communication. The robot uses the ultrasonic
sensor for detecting obstacle found in its path; mine sweeping sensor is used to detect the mine in
the field. After detecting the mine the controller sends the alarm message to monitoring center
using Zigbee communication. From PC the robot can be controlled and monitored, the robot has
2. digital compass which shows the direction of moving robot. Using the compass data the robot
moves to desired destination.
