DTMF Based Low-Power Consuming Autonomous Mining Companion Robot with Multiple Sensing Subsystems

In constantly developing countries, all of the major resources are obtained via. mining industry; an industry that is a bliss to the society but also faces some hidden dangers underneath to obtain the resources and accelerate the growth of human existence. The miners are prone to hazardous gases like carbon monoxide (CO), altitude threats, breathing problems and earthquakes. Therefore, the motivation of this project is to combine all the features necessary to help overcome the dangers in the mines by designing an autonomous based 4-wheel drive companion robot, controlled using an Arduino Uno microcontroller and dual-tone multi-frequency technology (DTMF). The DTMF technology can be used to control the robot from a wide range far distance without being in the mines. Multiple sensors are also interfaced without any programmable devices to detect light, temperature and gases in the environment. This project aims in combining all the various factors, reducing costs so as to make them affordable as well as effective against all the existing problems for the underground miners.
