Service work in the hospitality sector has a particular impact as it translates into high labour costs and, at the same time, represents a constant risk – whether it is because of sick leave or, more generally, because of a skills shortage. Using robots for the physically demanding service work thus seems sensible for several reasons. The CLOi ServeBot by LG Electronics, a South Korean manufacturer of chiefly entertainment and home electronics, is one such solution. The robot can assist service personnel but also bring meals to tables independently and communicate with guests via a display, provide information and later carry empty dishes back to the kitchen. It is equipped with sophisticated navigation and sensor technology, recognises obstacles and moves safely and smoothly, in part due to the independent suspension of each of its six wheels. This also allows it to transport drinks without spilling them. If energy levels should run low, the robot will, of its own accord, drive to its charging station. The serving unit consists of three height-adjustable trays so that meals can be deposited securely. Each tray is designed for loads of up to 10 kg. There is also space for storing cutlery, menus and other items. The shape of the supporting structure tilts backwards slightly to make sufficient space for the presentation and placement of meals. Weight sensors allow the CLOi ServeBot to know when meals have been removed. A cleverly integrated 10.1” touchscreen display helps management and service personnel with configuration and attending to customers. This can also be operated via a mobile app. The display can furthermore be used to communicate with guests, to share suggestions, information or show advertising. Alternatively, it can display a friendly digital face to give the robot more character. The jury praised the “high user-friendliness of the CLOi ServeBot and the many different options it offers for tailored customisation.” It scored highly because of a “design that finds an extremely minimalist approach to fulfilling a function. It is thought through down to the last detail, which results in a particularly harmonious overall appearance.”
