The metal detector robot is a novel method for identifying metal objects and detecting landmines. Although traditional procedures are prone to unintentional detonation, safer solutions must be developed. This paper presents a solution in the form of a robot with a metal detector that uses coil induction to detect metal precisely and is operated by an Android-based smartphone. Essential components include motors with DC that are managed by an Arduino UNO microcontroller and an LCD interface that shows measured metal frequencies in real time. When metal is discovered, the robot immediately provides feedback by making a loud buzzing sound and displaying the detected metal frequency on the LCD interface. The metal detector robot's effectiveness has been thoroughly tested, and results show that it can be controlled remotely from an Android smartphone up to 15 meters away. The detector head's detection radius reaches up to 88 millimeters, confirming accuracy in locating metal items, even potentially dangerous landmines. The metal detector robot emphasizes increased safety and accuracy while providing a viable solution to the problems associated with landmine detection. It is useful for community safety and landmine clearing efforts in conflict-affected areas because of its remote controllability and integration of cutting-edge technologies.
