This article presents a guided virtual reality (VR) simulation for the assembly of a robotic arm, developed in Unity 3D using the VR Builder framework. The simulation is designed for educational and training purposes, targeting engineers and technical professionals seeking an interactive understanding of mechanical assembly processes. It runs on the Meta Quest 3 headset in full VR mode, using controllers for object interaction. The primary aim is to demonstrate how immersive environments can enhance comprehension of part functionality and assembly order through intuitive interaction and audio guidance. The simulation consists of a short assembly sequence involving the basic components of a robotic arm. As the user progresses through the steps, audio instructions are triggered automatically to explain each part's name, purpose, and placement. These instructions are generated using text-to-speech tools, ensuring clarity and consistency. Although the simulation covers a simplified process, it serves as a proof of concept for more complex systems with larger assemblies. By combining spatial interaction with contextual audio cues, the simulation offers an engaging training method that can be expanded for industrial or educational use. The project also explores the practical potential of VR-based instruction for environments where hands-on access to real equipment is limited. Future development will focus on integrating hand-tracking to provide a more natural and accessible user experience.
