Service robots are a broad category of robots used to perform various service-related tasks. The most common types of service robots you will see are concierge robots and hospitality robots. Guardforce Hong Kong, for instance, has launched a concierge robot which automates visitor registration, controls access points through facial recognition and offers multi-media information, making it perfect for commercial buildings, events and exhibitions. Guardforce also has a hospitality robot for malls which provides a shopping guide, chat function and the ability for customers to download coupons. It makes for a perfect, single-point customer service solution.
