Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of service robots, in particular to a service robot with multi-directionally adjustable interactive screen group. BACKGROUND

[0002] With the rapid development of technology, service robots are increasingly widely used in various fields. Service robots usually have multiple functions, aiming to provide convenient services and efficient solutions for people. Service robots are generally equipped with interactive screen groups for information interaction with users, display of operation interfaces, and provision of feedback. However, the current interactive screen groups of many service robots have the problem of inconvenient height adjustment and angle adjustment.

[0003] When the interactive screen group cannot be adjusted in height, it brings many inconveniences to users of different heights. For example, a user with a higher stature may need to bend over to see the content on the screen, and long-term maintenance of such an uncomfortable posture can easily lead to physical fatigue. A user with a lower stature may need to stand on tiptoe or use other objects to view the screen, which not only affects the user experience but also may pose a safety hazard. For scenarios that require interaction at different height positions, such as in a hospital, a doctor may need to interact with the service robot in different states such as standing and sitting. The fixed-height interactive screen group cannot meet the diverse needs of such scenarios.

[0004] At the same time, the inability of the interactive screen group to adjust the angle also has obvious defects. Under different lighting conditions, a fixed-angle interactive screen group may have a reflection phenomenon, making it difficult for the user to see the screen content. In addition, when the service robot is placed in different positions or the user is at different angles, the fixed-angle interactive screen group may not be directly facing the user, requiring the user to adjust their position to adapt to the interactive screen group, which greatly reduces the efficiency and convenience of interaction. In some special application scenarios, such as in a display area of a shopping mall, the service robot needs to attract the attention of customers in different directions. If the interactive screen group cannot adjust the angle, it is difficult to achieve the best display effect. It can be seen that the current problem of inconvenient height adjustment and angle adjustment of the interactive screen group of the service robot seriously affects the user experience and the practicality of the service robot, and needs to be solved to improve the performance and adaptability of the service robot.
