The embodiment of the invention provides a service processing method based on a robot. The method comprises the steps of receiving identity information of a user and a service business type selected by the user; allocating a queuing number to the user according to the number allocation condition of a queue corresponding to the service business type; prompting the user to prepare required data according to the service business type; verifying whether the data prepared by the user is qualified or not; and sending prompting information representing data qualification and the queuing number of the user to a number calling platform if the data prepared by the user is qualified, thereby enabling the number calling platform to determine the next called queuing number according to the queuing number of the user and the prompting information. The number calling platform can adjust the number calling sequence according to the queuing numbers of the users and the data preparation conditions of the users; therefore, when there are multiple users queuing for service, the service sequence can be timely adjusted according to the data preparation condition of the users, and the service processing efficiency can be improved.
