Marvin is a mechanical engineer, holds a master's degree in computational fluid dynamics. he is a first-year Ph.D. student at Purdue University working with mixed reality apps oriented to teach fluid power concepts.
Dr. Jose M. Garcia-Bravo graduated from Los Andes University in Bogota, Colombia with a B.Sc. in Mechanical Engineering in 2002. He moved to the United States in 2003 and completed his M.Sc.E in 2006 and Ph.D in 2011 from Purdue University. He worked as a Research Assistant Professor at IIT in Chicago from 2011-2012. In 2012 he returned to Purdue to serve as an Assistant Professor at the Purdue Polytechnic Kokomo. Dr. Garcia-Bravo, joined the School of Engineering Technology at Purdue main campus in 2015, he is currently an Associate Professor for the Mechanical Engineering Technology program where he has a special focus on fluid power (hydraulic systems) research and instruction.
Dr. Garcia-Bravo investigates how hydraulic systems can improve the performance and efficiency of heavy duty vehicles. He also researches techniques for the creation of flexible components with embedded sensors using additive manufacturing for robotics, rehabilitation and industrial applications. During his time at Purdue, he has been awarded several grants to develop technology for the improvement of fluid power systems. As the director of his research group at Purdue, he received funding for the development of contamination resistant valves for the throttle control of fighter jet engines. The resulting design of this project generated a modified poppet valve that improved its response time from 40ms to 10ms. He has developed with his students an IoT irrigation system for water deprived areas in Arequipa, Peru. He has also conducted research in novel methods for the hybridization of electrically powered drive trains using hydraulic accumulators. Most recently he is developing an autonomous micro-drilling robot for underground applications.
More recently, he has been studying the principles for the creation of startup companies and have been personally interacting with industry professionals in the truck, automotive and off-road sectors.
Masters student within Purdue University's Polytechnic Institute graduate program. My research is in the field of engineering technology, studying the viability of Mixed Reality as a fluid power educational tool.
Fluid power education is most effective when conducted with hands-on applications and real-life projects. To optimize the students’ understanding of fluid power systems, they need to interact with individual components and systems made by these components, ideally during their operation. However, this effective and widely implemented approach is limited in execution because of safety concerns, budgets, the number of participants, visibility, and available space. In addition, physical testing environments must be properly instrumented to showcase system changes and operations, which can be costly and time-intensive. This work showcases a solution to these challenges by introducing a fully immersive and interactive Mixed Reality (MR)/Virtual Reality (VR) laboratory for gear pumps. The laboratory exercises allow students to interact with parts and/or systems in a safe and immersive manner and help them gain knowledge using guided tutorials. This is achieved using Microsoft HoloLens, mixed reality smart glasses, to present students with interactive CAD models of assembled fluid power components and a tablet computer used for virtual interaction. This paper presents the procedures and materials used to create both a virtual gear pump and a relief valve, including their virtual assemblies, computational fluid dynamics, and animation of the parts interacting within them. The MR and VR devices show instructions and advice so that students may learn how the components and the fluid operate within a component and offer interactions with their moving parts to identify their individual parts. This allows students to identify the parts of a pump and assemble them. Three programs are used in conjunction with the Microsoft HoloLens and a tablet to create interactive experiences: (1) Autodesk Inventor Pro is used as the CAD modeling software to build virtual parts, (2) Unity functions as the environment building engine to house the project and (3) Ansys CFX for the fluid simulation to understand how the fluid behaves in the parts. In this paper, the authors demonstrate how these instructions are created and modified in real-time to better suit the needs for instruction and training in the fluid power classroom.
