Abstract: An audio-visual perception system includes an audio perception module and a visual perception module, respectively receiving sounds and images of a subject and converting them into audio and visual signals. At least one of the above two modules is a first perception module having more than one working mode. A processing and control module controls the first perception module to switch a working mode thereof based on the audio or visual signals received from one of the two above modules other than the first perception module. An audio-visual perception apparatus having the audio-visual perception system is also disclosed, which can be used as a robot control unit (RCU) mounted onto a robot, allowing a human-in-the-loop robot operator to visually and audibly monitor the subject in a surrounding of the robot. The RCU can switch between a RCU mode and a cell phone mode.

Abstract: A network path optimization method includes: in response to a network access request, computing and sending an optimal path having a path code and carrying a path parameter; adding a path tag to the optimal path based on a real path; determining a parameter variation between the optimal path and the real path based on the path parameter and the path tag; and updating the optimal path and the path parameter based on the parameter variation.

Abstract: A method for testing software includes: determining influencing factors which influence implementation of a target function of the software; constructing a test case set for each of the influencing factors; inputting the test case set corresponding to each of the influencing factors to the software; enabling the software to run the test case set; calculating an accuracy of each of the influencing factors against implementation of the target function of the software according to a running result of the test case set run by the software; determining, according to the accuracy achieved each of the influencing factors, whether a predetermined qualification condition is satisfied; determining that the software is tested to be qualified if the predetermined qualification condition is satisfied; and determining that the software is tested to be unqualified if the predetermined qualification condition is not satisfied.

Abstract: A route selection method based on hybrid resources, the route selection method being applied to a server, the server being communicably connected to a multi-node network, the multi-node network including at least two network nodes, wherein the method includes: constructing a directed graph for the multi-node network, and constructing a directed edge for each of the at least two network resources among the network resources if the at least two network resources are included between any two network nodes; and receiving node information of various network nodes, acquiring a delay weight value between any two network nodes under any network resource based on the node information, and assigning the delay weight value to a corresponding directed edge.

Abstract: A robot character setting method includes: at a robot: adjusting an attribute value of at least one character attribute in a preset character feature according to feedback from a user, the character feature including a plurality of character attributes, each of the character attributes having an attribute value; and performing an action or speech according to the attribute value of the character attributes in the current character feature.
