The present disclosure relates to a semantic processing method of robots, including: receiving, by a semantic processing platform, a voice request from a robot, performing a sematic analysis on the voice request to obtain a current sematic intention, determining whether a response matching the current semantic intention is stored in a database, obtaining the response from the database if determining that the response is stored in the database, obtaining the response by accessing a third-party application corresponding to the current semantic intention if determining that the response is not stored in the database, and transmitting the response to the robot to guide the robot to perform a corresponding action. The present disclosure further provides a semantic processing device.
