The Anbot robots are oval-shaped and resemble the Star Wars 'R2D2' robot or the Daleks from Doctor Who, EFE news reported.
The bot's face has a digital display and a high-definition camera to take pictures of travellers at one of the country's busiest airports for analysis.
The role of these devices, for now, is similar to that of a security camera, but with greater mobility as they can move at speeds of up to 18 kph.
They are also equipped with a defence mechanism: an extendable arm that produces an electrical current.
AnBot was developed by a university in the central city of Changsha and may be used to patrol schools and banks.
The robots can also look for explosives, weapons and drugs and are priced at $15,000.
