News editors obtained the following quote from the background information suppli ed by the inventors:“Mobile robots have been gradually applied to public servic e scenarios. For example, more and moremobile robots are used in restaurants, o ffice buildings, and hotels to provide delivery services.“The design of mobile robots not only needs to pay attention to a structural str ength and a stability ofsupports, but also pays more and more attention to a un iversality of the robot, otherwise the applicationof the robot may be limited. Mobile robots in the prior art generally design support structures in themiddle of two sides of a casing. This design determines that they can only be adapted to large arc doorplates. However, it is difficult to install large arc door pla tes, so that the robot with the support structureprovided in the middle of two sides of the casing are usually put into use without door plates.
