1. AUTONOMOUS NAVIGATION ROBOT FOR
LANDMINE DETECTION APPLICATIONS
Introduction:
Antipersonnel mines may exist in any environments near human beings and threat their
lives. It is more difficult to detect and remove these mines especially if they exist in unstructured
environments or if they are close to crop fields. According to the United Nation statistics, more
than 100 million landmines exist in the ground in more than 60 countries causing 10,000 deaths
and 20,000 injuries annually. The mine clearance cost is greater than the budget of poor
countries that suffer from mines. In addition, this operation is usually performed manually,
which is slow and dangerous. Therefore, demining robots have been used to perform such
dangerous task instead of humans. The existing demining robots have limited maneuverability,
which does not allow the robot to navigate within the environment easily. To get high
maneuverability, some robots use Omni directional wheels or differential steering type.
However, these mechanisms cannot work well in rough environments since they lack the
suspension system or any other mechanisms that guarantee the stability. On the other hand,
legged demining robots were used since they show high maneuverability in unstructured
environments. However, they require high control effort besides the fear from tipping-over.
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 navigation robot
with mine 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 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

2. field. After detecting the mine the controller sends the alarm message to monitoring center using
Zigbee communication. From PC the robot can be monitored, controlled and moves to desired
destination.
