A Corrigendum on
A Comparison Between Two Different Approaches for a Collaborative Mixed-Virtual Environment in Industrial Maintenance

by De Pace, F., Manuri, F., Sanna, A., and Zappia, D. (2019). Front. Robot. AI 6:18. doi: 10.3389/frobt.2019.00018

In the original article, there was a mistake in Figure 3, Figure 7, and Figure 8 as published. Due to non-disclosure agreement complications, three figures of the paper should be replaced. The paper's authors apologize for these errors and they ensure that the main subject of the figures has not changed, only a few adjustments have been made to the background and very few details have been cut off from the images. These adjustments do not compromise the reading of the article in any way. The three figures are the following (notice that the same name conventions has been used). The original article has been updated.
