Underground Material Handling Using PLC and HMI

Abstract

Underground material handling using Programmable Logical Controller & Human Machine Interface helps us to hold the materials (books) which are stored in underground will be taken above the ground if necessary with the help of Two Access Robotic Arm.
Nowadays each and everything is getting smarter in its own way. We used to store the excess materials in a store room or in some other place from where we can access it in support of upcoming use and it needs man power. Instead of using man power, here we are using automation to access the materials. Storing materials in the underground is an effective method. In this project HMI acts as an input unit as well as a display unit, it helps us to give the input to proceed with the process. PLC is used to control the process with the help of coding. Books are stored in racks under which there is a moving bed and the two access robotic arm is used to pick and place the book in a moving bed (base plate). The working of the base plate’s movement and two access robotic arm’s forward, reverse, pick and place actions are controlled by DC motors.
