Arnold-II Service Robot for Restaurants

In fact, these two aspects are not at odds at all; they actually complement each other visually. The design language of the 1970s and 1980s often features smooth and rounded forms, which align perfectly with the visual language of a service robot. During the initial concept phase, I had already decided on this design style, and I focused on enhancing elements that convey a sense of approachability. For instance, I carefully chose colors that would support this vision: the vibrant orange not only boosts the robot’s friendly appearance but also stimulates the appetite of restaurant patrons. In this way, the design language of the robot seamlessly merges retrofuturism with the welcoming atmosphere of a fast-food restaurant.

This robot is designed for fast-food restaurants, so high efficiency is essential. On smooth surfaces, wheels are definitely more efficient than walking; however, wheels cannot operate effectively on complex terrains. Therefore, the robot is equipped with dual locomotion. These two modes of movement not only increase the robot's operational efficiency but also provide the capability to navigate more challenging terrain when necessary.

First of all, as a restaurant service robot, it should have all the functions of a human waiter, such as taking orders, serving food, and processing payments. Therefore, the first step in designing the robot was to implement these basic functions. For instance, the robot needs to be able to communicate with people, so it is equipped with a camera, microphone, and speaker. If customers cannot communicate with the robot using voice, they can choose to use the keyboard and screen on the robot for text-based interaction. Since the robot already has a keyboard and screen, the payment functionality is seamlessly integrated, enabling it to perform all the tasks of a human waiter. On this foundation, I decided to add features that human waiters could never have, such as an oven built into the robot's waist and a vacuum cleaner at the base, making the robot more versatile and powerful. While designing these features, I consistently maintained a smooth and rounded design language, applying this visual style to every aspect of the robot.
