- 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.
- Industrial collaborative robotics platformPublication . Vicente, L.; Lomelino, P.; Carreira, F.; Campos, F. M.; Mendes, Mário J. G. C.; F. G. Osório, A. Luís; Calado, João Manuel FerreiraCyber-physical systems are not designed to integrate an industrial collaborative network when their integration with other systems is required. It is necessary to adopt a strategic model of integration and value creation that allows the interoperability of equipment supported by open technologies, based on the concepts underlying Industry 4.0. To this end, a conceptual information architecture is proposed to manage industrial robotic platforms based on a Cyber Device Bus design. The challenge is to contribute to an open technological framework involving computer systems, cyber-physical systems, and IoT elements in a logic of integration by adaptation without the need for specialized adapters. Adaptation occurs through the adoption of the informatics System of Systems (ISoS) technological framework, providing an integrated service-oriented (micro-services) view of technology elements and establishing cooperation between computer and cyber-physical systems under different responsibilities and based on a diversity of technological frameworks.
- Supervision System 4.0 for a Road Tanker Washing Robot ManipulatorPublication . Vicente, L.; Carreira, Fernando; Campos, Francisco M.; Gonçalves Cavaco Mendes, Mário José; Calado, João Manuel Ferreira; Carvalho, GamboaThe washing of road tankers is currently still a manual process that requires an operator to place the washing head into the tanks. To increase productivity and operator safety, it is essential to implement automated systems with Fault Detection and Isolation (FDI) capabilities. On the other hand, the industry 4.0 paradigm promotes the use of collaborative systems that integrate with the other organization’s processes. Realizing this new vision requires Supervision, Control and Data Acquisition (SCADA) systems with FDI modules that integrate with collaborative systems and promote the digitalization of companies. This paper proposes a SCADA system for a new road tanker washing robot, aimed at integrating all systems and communication networks of the organization and future FDI modules. To this end, this paper proposes a communication architecture based on open protocols and a common database to connect SCADA to the lower and higher levels of automation. Furthermore, this paper describes the various aspects of SCADA system development, from synoptic design to validation. To support the development of the SCADA system, a Digital Twin (DT) of the road tanker washing robot was used, allowing to test and validate its functionality through this virtual prototype. The results show that the proposed SCADA system and underlying information architecture are suitable for supervision of a robotized wash operation and that the use of a Digital Twin facilitates SCADA system design and validation.
- An electro-pneumatic prototype to support the teaching of industry 4.0 conceptsPublication . Francisco, Miguel B. R. M.; Mendes, Mário J. G. C.; Calado, João Manuel FerreiraThe appearance of industry 4.0 and the internet of things allowed to shorten the gap between the consumer and the product industry, with the introduction of new digital processes. With this in mind, a project of an electro-pneumatic laboratory prototype tosupporttheteachingoftheindustry4.0conceptswas proposed.Fortheconstructionofthelaboratorysystem was developed a typical industrial electro-pneumatic process (at scale), for which some support components were constructed using 3D modelling. For the automation part of the this system, the control platform of the programmable logic controller, type of programming language and creation of the code were developed. For the supervision system and remote digital control, the human machine interface is based in web pages using a common web browser, with the possibility of decentralized access in every tablet and smartphone. This prototype was simulated and tested, and it will help in the teaching of the 4.0 industry concepts.
- 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).
