A microcontroller is a small and low-cost computer built for the purpose of dealing with
specific tasks. Microcontrollers are mainly used in products that require a degree of control to be
exerted by the user. It is generally built using a technology known as Complementary Metal Oxide
Semiconductor. A metal detector robot designed as a new application of microcontroller. It used the
microcontroller to control its mechanism movement. The robot has two links and two joints
supported on moving table to make its movement easy. A carriage vehicle used for carrying robot
which used the skid steered wheeled types to make its movement easy and safety on ground open
area. The robot’s movement orientation done very accurate depending on link between the
microcontroller and the user’s hand remote.
