Vocational training in VR

One of the prominent EU funded projects in the city of Sisak aimed to establish the infrastructure of the Regional Competence Center of the Sisak Technical School in the field of electrical engineering and computing. The main idea was to renovate the currently neglected complex of the former military barracks and equip it with modern technologies, thus improving vocational education in the Sisak-Moslavina County.

In the light of that, part of the project involved creating a new curriculum for a vocational high school where students could choose between the Robotics or Computer Game Development specialization. Besides hands-on learning on the real robotics equipment and systems, their everyday learning approach is intended to involve immersive lessons in VR.

These lessons are intended to follow the curriculum and bring closer complex robotics systems  to students  (such as hazards and emergencies, changing parts, etc.)

The Solution

Our part of the project was to create 60 independant VR experiences for the Robotics specialization curriculum. They are spread across all 4 study years and follow the lessons from all 15 study book materials. 

In close coordination with the book authors, school board and our client Algebra, we pinpointed 4 lessons per book which need to be shown in VR, due to complexity of the equipment or the methodology and theory behind them. Lessons consist of the theoretical part with a voiceover and corresponding custom models and animations. After each lesson, an interactive quiz is presented to the students, where they can test their knowledge of the lessons they have just completed.

All VR lessons are set in a custom-made 3D environment representing a real location where practical training takes place for students (a hangar). Some notable features from the lessons include the creation of multiple detailed 3D models of industrial robots, optimized for Unity’s real-time engine (5-15k polygons each). Examples include Fanuc ARC Mate 120iD/35, Fanuc ARC Mate 50iD, RB-Kairos+, RB-1-Base, HSTec Cell, and Cylindrical robot arm.

We have also developed a large number of specific 3D models for theoretical lessons from textbooks (simple and complex mechanisms, cross-sections, diagrams, drones, sensors in action, etc.), as well as numerous animations of various mechanisms and specific devices.

The Result

We successfully produced 60 VR experiences in a time-bracking fashion to be used for a 4 year academic programme. The school and its teachers received an additional immersive tool which can help them share knowledge with students in a modern and effective way.

Our real life modeling and modern curved UI ensures that all the experiences will look appealing even after a couple of years. Also, our codebase, loading system and optimization of hardware resources used by the mobile headset, guarantee longevity and usability of the targeted equipment.

Project Highlights

We have created a custom curved UI panel which follows the user position and retracts to the side when the models and animations are displayed.
