Indicative price: Not stated
Intended use, per the manufacturer: Suited for industrial inspection, park logistics, and emergency rescue and more.A2-W does not appear in the manufacturer's English product navigation menu, where A2 is listed under 'Robot - Industry'; the Chinese-language navigation lists A2-W alongside A2 under the same “industry-level” group. The category comes from the product page's own sentence. The same page also calls the robot an 'Industrial-grade mobile platform', which describes build quality, not a use.
