- A gantry robot automatic positioning system using computational visionPublication . Beites, Nuno; Dias, Manuel; Gonçalves Cavaco Mendes, Mário José; Carreira, Fernando; Campos, F.; Calado, João Manuel FerreiraWith the new industrial revolution (industry 4.0) under way, there is a need to automate/digitalize even the simplest processes to keep companies competitive, efficient and secure. This work proposes an automatic and robotic positioning system with position control through the image of video cameras. The objective is to propose this type of automatic system to companies aiming to improve robotic systems operations that are often controlled manually and with associated risks. The developed system was tested in simulation (using Matlab) and in an experimental scale prototype.
- Fault diagnosis system via internet applied to a gantry robot — A proposal for industry 4.0Publication . Gonçalves Cavaco Mendes, Mário José; Neto, Íris M. M. S.; Calado, João Manuel FerreiraCurrently, due to the global competitiveness and the need for cost reduction, companies are more and more interested in increasing the availability of their production systems. Moreover, Internet is becoming indispensable for the distribution of information throughout the world, becoming critical to implement distance supervision systems which detect and diagnose faults. Thus, the concepts of Industrial Internet of Things and Industry 4.0 arise, where from a large amount of available information decisions can be quickly taken, preventing the occurrence of faults and failures. For this reason, the system proposed in this paper is an Internet based fault diagnosis system (FDSvI), it has applicability in a wide range of industrial processes and it has been applied and tested on a gantry robot. This system was developed using software like the graphical programming software LabVIEW ® using the Datalogging and Supervisory Control LabVIEW module and the OPC Servers for the communication between Siemens ® S7-1214C programmable controllers and the fault diagnosis system (FDS).
