This joint National Science Foundation - Swiss National Science Foundation (NSF-SNSF) project aims to advance research in multi-human-multi-cobot collaboration in industrial settings. Collaborative Robots (Cobots) are increasingly being deployed in factories to assist workers with repetitive tasks or heavy lifting. Typically equipped with a Graphical User Interface and simulation software, these cobots are designed to be easily programmed by non-experts. However, while programming a single robot may be straightforward, coordinating multiple cobots to collaborate effectively with human workers can present challenges in a factory environment. During assembly processes, these robots often work alongside humans, helping to lift heavy components or provide necessary tools and materials as required. To effectively teach cobots their tasks, human operators must have a solid understanding of three-dimensional spatial processes. Simultaneously, the cobots must learn to interpret and adapt to human actions within their workspace. To address these challenges, this project introduces a Virtual Reality (VR) framework that facilitates collaboration between humans and cobots. The system aims to empower multiple users to interact using hand gestures, eye gaze, and speech within a physics-based VR simulation environment, thereby simplifying the process of teaching robots industrial tasks.
