Augmented Reality Enabled Human–Robot Collaboration

Augmented Reality (AR) provides an interactive approach to combining the physical manufacturing environment with computer-generated virtuality. However, it is still challenging to establish an efficient AR system due to the complexity of the actual manufacturing environment, and the difficulties in human–robot collaboration (HRC). In this research, a feasible AR system is developed with a novel closed-loop structure. A feasible AR-based human–robot interaction method is also developed based on the HoloLens device, together with an advanced compensation mechanism. Compared with the previous research, the proposed work aims to accurate robot control based on AR. The proposed system is then implemented and validated through case studies, and quantifiable performance assessment on system response time, compensation accuracy, and other characteristics.
