MECCANO is a multimodal, egocentric video dataset for human behavior understanding in industrial contexts. The dataset was obtained in an industrial-like scenario where participants were asked to play with a motorcycle toy model. A total of 20 object categories were considered, including:

• 16 categories for 49 component classifications,
• 2 tools (screwdriver and wrench)
• An instruction manual and a partial model.

The dataset contains 11 training videos and 9 validation/testing videos, including 8,857 video clips.
