Such a working environment not only easily causes fatigue among staff but may also affect service quality, especially during peak hours when the workload of staff is even heavier.

[0005] Complexity of the restaurant environment: Restaurants usually have a relatively complex layout, including tables, chairs, customers, kitchens, and other elements. This requires service robots in restaurants to have high-precision navigation and obstacle avoidance capabilities to ensure the smooth completion of tasks without interfering with normal operation order.

[0006] Diversity of service requirements: The service requirements in restaurants are not limited to food delivery and cleaning. Modern catering services also require more flexible and efficient interaction methods. Customers hope to interact with service robots in a natural way, such as voice control, touch screen operation, gesture recognition, etc., to provide a more user-friendly service experience.

[0007] Complexity of cleaning tasks and hygiene requirements: Cleaning tasks in restaurants are not just about cleaning the tabletop. More importantly, it is about cleaning the floor and maintaining the hygiene around the kitchen. These tasks require robots to be able to execute in a complex restaurant environment, have sufficient cleaning capabilities, and not affect other normal operations during work.
