We invite you to visit the exhibition “Kaleidoscope” by Assoc. Prof. Mindaugas Užkuraitis of the VILNIUS TECH Faculty of Architecture. The exhibition is on view in Gallery A (Saulėtekio al. 14, second floor). About the Author Mindaugas Užkuraitis is an Associate Professor at the VILNIUS TECH Faculty of Architecture, Head of the Department of Design, Chief Artist at LRT, and a member of the Lithuanian Design Forum. His professional practice includes scenography for television, concerts, and public events. He has created stage designs for the national selection finals of Eurovision, the finals of Dainų dainelė, the Lithuanian of the Year Awards, as well as for TV programs such as Lietuva kalba, Rinkimai, LRT Forumas, and other projects.   About the Exhibition “In this exhibition, I continue my exploration of color, layering, and fragmented forms. I am interested in how different elements come together into a unified image that constantly shifts depending on the viewer’s perspective. The principle of a kaleidoscope resonates with me because there is no single stable composition – the image is continuously changing, yet the structure remains. Working with spray paint, stencils, and layers, I aim to create visual systems where both chance and control emerge. These works are not about a specific narrative – they are about the process of seeing: how an image forms, breaks apart, and reassembles into a new whole,” notes the exhibition’s author, Mindaugas Užkuraitis. The meeting with the author will take place on May 21, 16:00 in Gallery A. The exhibition in Gallery A  will be on view until May 29. Virtual exhibition >>> Archive of virtual exhibitions >>>

VILNIUS TECH Library invites you to follow the published new dissertations. The dissertation „Control of Robot Path Using an Artificial Intelligence System by Fusing Sensor Signal“ („Roboto trajektorijos valdymas dirbtinio intelekto sistema suliejant jutiklių signalus“) prepared at VILNIUS TECH by Vygantas Ušinskis. The dissertation was prepared in 2021–2026. Scientific consultant – Prof. Dr  Vytautas Bučinskas. The dissertation was defended at the public meeting of the Dissertation Defence Council of the Scientific Field of Mechanical Engineering in the Aula Doctoralis Meeting Hall of Vilnius Gediminas Technical University at 10 a.m. on 30 April 2026. The dissertation examines the problem of local robot navigation, where sensor data must be processed in real time to assess the environment and generate an adaptive motion trajectory. The research object is a local navigation system with sensor fusion for mobile robots operating in tunnels and confined channels. Navigation is divided into four parts: environment assessment, localisation, path planning, and motion execution. The analysis of localisation technologies enables the selection of an effective sensor set for obstacle detection. Heuristic and artificial intelligence methods allow generating an optimal trajectory that avoids collisions and maintains the goal. The work addresses navigation and obstacle detection in human-inaccessible environments using a cost-efficient combination of active and passive sensors, with experimental validation of the system’s performance. The dissertation consists of an introduction, three main chapters, conclusions, references, and a list of the author’s scientific publications on the topic of the dissertation. The introduction presents the problem, relevance, research objective and tasks, methodology, scientific novelty, practical significance, and defended statements, as well as the author’s publications and the structure of the dissertation. The First Chapter presents a literature review, including an overview and comparison of global and local path-planning methods, localisation technologies and their combinations, and sensor-fusion approaches used in mobile robots. Key factors affecting reliable navigation are identified, forming the basis for the dissertation tasks. The Second Chapter describes the developed research methodology for autonomous tunnel navigation: the operating principles of the red, green and blue (RGB) channel-camera- and laser-based optical obstacle detection system, sensor-fusion techniques, and the application of modified Vector Field Histogram (VFH) and machine-learning-based path-planning methods. The Third Chapter presents the research results: optical system experiments, path-planning simulations, a comparison between machine-learning and modified VFH methods, and the testing of the constructed robot prototype in a laboratory environment. Five research papers have been published on the topic of the dissertation: three in journals indexed in the Web of Science database, and two in conference proceedings. Additionally, five conference presentations related to the dissertation topic have been delivered in Lithuania and abroad. Doctoral dissertation readers can search via VILNIUS TECH Virtual Library.
