Abstract: Provided in embodiments of the present application are a method and apparatus for user registration and electronic device. The method includes: after obtaining a wake-up voice of a user each time, extracting and storing a first voiceprint feature corresponding to the wake-up voice; clustering the stored first voiceprint features to divide the stored first voiceprint features into at least one category, wherein, each of the at least one category includes at least one first voiceprint feature which belongs to the same user; assigning one category identifier to each category; storing each category identifier in correspondence to at least one first voiceprint feature corresponding to this category identifier to complete user registration. The embodiments of the present application can simplify the user operation and improve the user experience.

Abstract: A smart device control method and apparatus, and a storage medium, relating to the technical field of smart devices.

Abstract: An omnidirectional ball wheel includes a ball wheel skeleton, at least three first wheels and second wheels. The ball wheel skeleton has a curved outer surface, is pivotable, and defines a first pivot axis. Each first wheel has a curved outer surface, is pivotably connected to the ball wheel skeleton, and defines a second pivot axis perpendicular to and intersecting the first pivot axis. The top of the outer surface of each first wheel is provided with a through hole to accommodate the second wheel which is pivotably connected to the ball wheel skeleton and defines a third pivot axis perpendicular to both the first pivot axis and the second pivot axis. The outer surfaces of the first wheels, the outer surface of the ball wheel skeleton and a portion of an outer surface of the second wheel are on the same spherical surface.

Abstract: The present disclosure proposes a method and an apparatus for generating an action sequence of a robot. The method includes: obtaining a directed graph, in which the directed graph comprises a plurality of nodes for instructing actions of the robot, and directed edges connecting the nodes; obtaining target actions involved in a task, and an execution order of the target actions; in the directed graph, performing a search in directions indicated by the directed edges to obtain a target path, in which nodes on the target path comprises target nodes corresponding to the target actions, and an order of the target path passing through the target nodes matches an execution order of the target actions; and generating the action sequence of the robot according to actions instructed by the target path and an execution order of the actions instructed by the target path.
