Mine Detection with 3 DOF Robotic Arm

Abstract

Mining is a major factor for the process of extraction of minerals from the Earth’s surface. Thee minerals can be of two types, metallic and non-metallic. In this project, we are focusing on metallic minerals/substances detection. But these materials are randomly located that their presence is not easily predictable. To make it easy and efficient to locate these materials, we intend to use robots in these areas to avoid save time and avoid risk causing to human life while deploying./extracting. This project throws a vivid light on how effectively we use robotics in the process of mining. The robot here is made to move on wheels that are controlled by two DC Motors which are drive-by L298 driver IC. A proximity sensor is connected to the tip of the robot arm. This sensor is used for the detection of metallic presence, so it uses a principle of the magnetic field for this purpose. Since mines are also metallic substances, this project can be used for both mining and military purpose as well. As the name suggests proximity, means closeness, when this sensor is made to come near a metal substance, an LED that is present over it is made to glow. This indicates the presence of metal. This project uses a wireless technology i.e. a Bluetooth module for the robot movement. All the components used in this are interfaced with Arduino, a microcontroller that can be easily programmed to instruct all the components. A buzzer is also connected so that it makes a buzzing sound when metallic material is detected.
