Land mines buried underground pose threats to lives and the economy. Detecting and removing them manually is dangerous and sometimes causes accidents. Robots can help detect land mines and other buried metals. The document describes a proposed robot that uses a metal detector based on electromagnetic induction to search for land mines and metals underground. When metal is detected, eddy currents are induced that generate a signal indicating the presence of metal.

2. Project overview
 Land mines buried under the ground causes
threat to the lives and affect the economy of the
nation.
 Detection and removing of these mines
manually is a dangerous task, which may
sometimes causes accidents.
 In such situations robots aid in detection of the
land mines. Not only can land mines, these
robots be used to detect any other metals
presented in the ground

5. Metal detector
 The operation of metal detectors is
based upon the principles of
electromagnetic induction.
 When the magnetic field of the coil
moves across metal, such as the coin,
the field induces eddy currents in the
coin.
 The single-coil detector is the one
used in a real metal detector.

6.  The eddy currents induce their own magnetic field,
which generates an opposite current in the coil, which
induces a signal indicating the presence of metal.
 We can also use an inductive proximity sensor, which
can detect only metal.
