Digital Twin-based human-machine collaboration and application approach for laser projection aided assembly of complex product

For the field assembly problem of large-scale complex products, many assembly processes are manually done by highly skilled operators. To improve the efficiency and quality level of assembly, a digital twin-based human-machine collaboration and application approach is proposed. On the basis of laser projection aided assembly, the operation mechanism is discussed in detail for visual assembly assistance of human-machine collaboration. The feasibility of the proposed approach is illustrated by an experimental case study.
