Bucharest, Romania Abstract: The rapid development of industrial digitalization and the improvements that Industry 4.0 has brought into the world of manufacturing has led to a significant need for flexibility in terms of industrial robotic applications. The aim of this paper is to present the improvement process of an existing industrial robot cell by adding a control cabinet that includes a PLC, relays, safety circuits and an HMI. The PLC design is oriented towards flexibility, compact form and connectivity, in order to provide a device that can be used both as a machine communication interface and as a tool for testing and simulation of robotic station logic through connection with a computer running dedicated software. Furthermore, the robotic application is improved by integrating an automatic tool changer that increases flexibility, provides a new concept for tool changing that can be electrically actuated and provides an improved framework for testing the control cabinet.

University "Lucian Blaga" of Sibiu, Faculty of Engineering, Romania Abstract: This study introduces a novel approach to real-time data acquisition and monitoring using the versatile ESP32 microcontroller, which is highly regarded for its flexibility and capabilities in IoT solutions. Sensor data is transmitted wirelessly via an open-source MQTT broker, which has been specifically adapted to meet the scalability requirements of modern IoT infrastructures. This method not only facilitates real-time data capture but also provides a robust platform for processing and visualizing the collected information by integrating efficient software solutions. The paper delves into both the hardware configuration, such as setting up the ESP32 and connecting it to different sensors, as well as the software development required to manage communication protocols and implement MQTT integration. The MQTT protocol is particularly beneficial due to its efficiency in data transmission with minimal bandwidth usage and low latency, making it suitable for fast, reliable communications, which are critical in IoT environments. Experimental results show that the proposed solution ensures high stability and fast response times, making it applicable in various domains. These include the remote monitoring and control of smart homes, where precision and quick response are essential, automation of industrial processes, and the development of intelligent environments. Moreover, the solution demonstrates significant potential for integration into Industry 4.0, with the ability to work alongside emerging technologies such as augmented reality (AR) for system monitoring and maintenance in industrial production settings. As a result, this system can play a pivotal role in optimizing industrial processes by offering a comprehensive solution for real-time control and data analysis in crucial industrial applications.

and Robotics, Bucharest, Romania Abstract: Biomaterials are usually
non-magnetic, non-corrosive, resistant and durable materials, with a pleasant
appearance and possibly recyclable. They are manufactured by clean and
efficient technologies, from high quality raw materials, which have
properties adapted to specific requirements. The paper presents research
on the obtaining of biocompatible austenitic stainless-steel type that have
been doped with chemical elements such as Cu, Ag and Ti,
which are known for their beneficial effects in terms of inhibiting the
ability of microbes and bacteria to proliferate. Following
the microstructural analyses, it was observed that the simultaneous addition
of these elements allows the grain refinement, with the effects of improving
the mechanical properties. Key words: antimicrobial,

The potential problems arising from joining different materials highlight the need to perform thorough testing. By studying a particular case, the paper establishes a link between the parameters of the welding regime and the method or combination of methods (NDT testing) that can lead to the identification of the imperfection generated by their alteration.

In an industrial context where optimizing resources and reducing environmental impact are priorities, but also in custom projects made with the help of additive manufacturing such as FDM, generative design is an innovative method based on algorithms that allows the automatic generation of optimized configurations of the input design. By defining parameters such as basic start geometry, preserve and obstacle geometries, this process produces design iterations tailored for maximum performance with minimum material used. The case study examines the benefits of this approach in reducing the volume of material required to manufacture a flange part, analyzing and comparing the performance achieved against the traditional design. The results indicate a significant reduction in material waste, with potential for 3D printing implementation to improve sustainability and efficiency. The article also discusses the challenges and limitations in adopting generative design in the industrial environment, including the requirements for integration into current workflows and adapted to rigorous safety and reliability specifications.
