Review On 4 DOF PLC Controlled Robotic ARM for Pick and Place Using IR Sensor And HMI

Abstract

Robotic arms are used in many of the industries, where humans can’t work efficiently. The conventional practices used in industries are the work done by the humans (workers) and as humans are working fatigue is there and hence accuracy of work and productivity will affect. Human-machine interface commonly known as HMI is deployed for control and visualization interface between a human and a process, machine, application and appliance. This paper attempts to provide PLC Controlled robotic arm for pick and place using IR sensor and HMI. Implementation of logic is done for pick and place robot in HMI and design a GUI for controlling and monitoring the working of the robot. The proposed paper is to develop a system for pick and place object of weight in between 2-5kg which is teachable i.e. configurable by human via HMI panel whenever object is come in front of IR sensor the controller gives signal to actuator to actuate particular joint as sets on HMI. This is to done for greater accuracy, precision and to work in hazardous conditions where it is difficult for humans to work. IR sensors are used to detect the objects presence as object come in front of that sensor controller gives signal to the actuators to actuated the required joints And accordingly movement of arm takes place object is picked and placed on one particular position, confirm by destination IR when object is placed at destination then only next cycle starts and again object is picked and cycle is repeated.
