Abstract: A system may include a controller coupled to a user interface. A user may provide user commands specifying mapping relationships between one or more audio inputs and one or more audio zones via the user interface. The controller may be configured to determine individual audio inputs to be outputted to individual audio zones based on a priority policy. The system may further include audio streaming applications coupled to the controller. The controller may launch the audio streaming applications to the user interface for interaction with the user. The audio streaming applications may provide audio streams to be outputted at the individual audio zones. The system may further include a streaming interface coupled to the controller and the audio streaming applications and configured to receive the audio streams. The streaming interface may be further configured to transmit the audio streams to output devices of the individual audio zones.

Abstract: A storage medium, a robot, and a method for generating navigation map are provided. By disposing a first lidar and a second lidar located higher than the first lidar, it constructs a first map corresponding to the first lidar based on first laser data collected by the first lidar, and calculate second positioning data corresponding to the second lidar during constructing the first map, constructs a second map corresponding to the second lidar based on the second positioning data and second laser data collected by the second lidar, and obtains a navigation map corresponding to the robot by fusing the first map with the second map, such that the fused map includes not only positioning information provided by the first map, but also obstacle information provided by the first map and the second map.
