Control and Operation of 4 DOF Industrial Pick and Place Robot Using HMI

Human-machine interface commonly known as HMI is deployed for control and visualization interface between a human and a process, machine, application and appliance. It is a graphics-based visualization of an industrial control and monitoring system. In this paper we intend to present the controlling of an industrial pick and place robot using 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 robot is interfaced with PLC and the PLC in turn is interfaced with the HMI. The HMI can be used to control the robot by giving control signals from the HMI panel and also it simultaneously receives the signals from the system to show the status of the robot operation. The HMI panels shows which arm of the robot is active during the operation. Advantage of this HMI controlled system is that the system is automatic and supervises continuously as a result of which faults can be monitored and acknowledged to the user.
