Small object search with RFID tags

This bachelor's thesis focuses on the development of a device for locating small-sized objects using RFID technology. An analysis of existing RFID technologies and their applications was conducted, which led to the selection of ISO 15693 and ISO 18000-3 standards for the development of the small-sized object locating device. Experimental results were obtained to study the detection capabilities of RFID tags under various conditions using the HBE-RFID REX setup. Structural, functional, and circuit diagrams of the device were developed based on the selected components: the TRF7970A RFID module from Texas Instruments, ID ANT310/310 antenna, ATXMEGA64D3 microcontroller, LM041L LCD screen, matrix 3x2 keyboard, LP9960115 battery, 2 LED indicators (red and green), and DC-DC buck converter (LM2596). Algorithms for the device's operation were developed for searching known tags, displaying saved tags, and searching for new tags, along with the corresponding software codes.

Mobile robotic welding cell

This paper examines the market for robotization in welding production. It proposes the development of a portable robotic welding cell based on these insights. The work is divided into four sections.The first section explores the current market for robotic welding systems and evaluates the necessity of integrating such systems into welding production. It discusses advantages like increased efficiency and precision, alongside disadvantages such as high initial costs and maintenance.The second section outlines essential criteria for designing a mobile robotic welding cell. This includes constructing a technical diagram detailing the location and set of required components, defining necessary dimensional criteria, and creating a 3D model and structural diagram to illustrate component interactions.The third section involves selecting components that meet the established criteria. A functional diagram is constructed to demonstrate how these components work together to achieve the desired functionality of the mobile robotic welding cell.The final section develops an electrical circuit diagram for the connection of components in the control device. It demonstrates the logical connection of components and their signal interactions using the Ladder programming language in PLC.
