🧠 Description

This project is part of the Bachelor’s Final Project in Computer Engineering, and its goal is to develop an educational virtual reality (VR) application that simulates the process of assembling and welding a 10s4p lithium battery pack.

The application allows students to safely practice the assembly process, eliminating physical risks and optimizing material usage.
The simulator recreates an immersive virtual classroom where users can interact with lithium cells, nickel strips, supports, and real tools modeled in 3D.

The project aims to promote practical and safe learning, aligned with the Sustainable Development Goals (SDGs), especially the goal of quality and inclusive education.

🧩 Technologies Used

Unity (C#) – Main engine for the virtual reality environment
Blender – 3D modeling of tools and components
XR Interaction Toolkit – Interaction and immersion management in VR
Oculus Meta Quest 2 / 3 – Devices used for testing and execution
Unity Hub & Unity Version Control – Project management and control
Google Drive & Plastic SCM – Storage and version control
