Introduction

Robotics involves the design, construction, operation, and application of robots—automated machines that can perform tasks autonomously or semi-autonomously. Virtual Reality (VR), on the other hand, immerses users in a computer-generated environment, facilitating interactive experiences through sensory stimuli such as visuals and sounds.

The intersection of robotics and VR leverages the strengths of both fields to create more intuitive, efficient, and immersive systems. This synergy enhances human-robot interactions, improves training methodologies, and opens up new avenues for innovation across multiple sectors.
