[0002] In the field of coffee beverages, coffee latte art, as an important part of enhancing the ornamental and artistic value of coffee, has always attracted much attention from consumers. However, the current coffee latte art technology on the market has obvious limitations and is difficult to meet the increasingly diverse market demands.

[0003] The existing coffee latte art technology mainly relies on two methods: manual production or robotic arm-assisted latte art. When making coffee latte art manually, although it can endow the works with a certain degree of uniqueness and artistic sense, limited by factors such as the personal skill level, creative inspiration, and physical strength of the barista, the pattern design is often relatively single, and it is difficult to ensure the consistency and stability of each cup of coffee latte art. At the same time, the efficiency of making coffee latte art manually is low and cannot meet the needs of large-scale production.

[0004] For the robotic arm-assisted latte art technology, although it improves the efficiency and stability of latte art to a certain extent, due to the limitations of its mechanical structure and the complexity of programming, it is still difficult to complete the production of complex patterns. The movement trajectory of the robotic arm is relatively fixed, lacking flexibility and creativity, resulting in the lack of diversity and personalization of latte art patterns and being unable to meet consumers' pursuit of unique and novel coffee latte art patterns.

[0005] With the continuous improvement of consumers' demands for coffee quality and personalization, single and simple coffee latte art patterns can no longer meet the market needs. Consumers expect to enjoy more diverse, complex, and artistically beautiful coffee latte art works. Therefore, developing a technology that can break through the limitations of existing technologies and achieve the production of complex and diverse coffee latte art patterns has become an urgent problem to be solved in the current coffee industry.
