Intended use, per the manufacturer: Robot - Industry Robot dog - industrial gradeCategory inherited from the base model, B2. The words are the manufacturer’s, but they were written about the base model. That they also cover this edition is our inference – which is why it is marked.Taken from B2. B2-W does not appear in the English product navigation menu (though the Chinese-language navigation pairs it with B2 under the same group), and its own page https://www.unitree.com/b2-w, read 2026-08-19, states no application, only 'Go Further with Higher Efficiency' and 'Brand New Intelligent Species'. The quote is B2's; Unitree does not say that B2-W shares B2's applications.
