For my masters degree work, I updated the human machine interface (HMI) control program for a robot welding cell. Due to an upgraded HMI, the operator’s work with the robot welding cell is easier and safer. Furthermore, a final testing procedure in the company Yaskawa Motoman is also simplified. Upgrade of the interface was needed because of the increasing safety standards in automated factories. The new interface operates on the already installed hardware equipment, so it can be implemented on any preexisting robot welding cell around the world.
The first part of my masters degree work depicts the design phase of the HMI and how it will be used. It also includes all the devices needed to operate and what is their intended purpose.
The main part of masters degree work explains how the upgraded HMI control program works. The beginning of the main part explains how the communication between the robot controller and the programable controller is established. Then a detailed explanation on the data transfer is given. The last part highlights the received data processing and preparation for the display on the HMI.
Masters degree work ends with the description of the debugging phase of the control program and with some plans for future improvements.
