Infographic: Robots at Your Service

Service robots assist humans in performing tasks that are either too dirty, dull, dangerous, or distant, excluding industrial automation. These semi-autonomous or fully autonomous robots perform domestic tasks—such as vacuuming or lawn maintenance; they work in hospitals, fields, and warehouses; they inspect infrastructure and explore deep sea; they entertain humans and provide directions and engagement at various events. The number of service robots being sold is increasing explosively. Some 361,000 professional service robots were expected to be sold in 2019, up from 271,000 in the previous year.
