In the era of intelligent media communication, the coexistence of social robots and human users has become a new scene in social cyberspace. The widespread use of social robots in the Russian-Ukrainian conflict has attracted much attention. Based on the basic recognition of social robots, this paper tries to clarify the essence of its concept, summarizes its characteristics of intelligence, sociability and sociality, and summarizes its practical application in the fields of news diffusion, network navy, political campaign and emotional compensation. Combined with the use of social robots in local hot issues, this paper analyzes the cognitive confrontation strategies adopted by social robots, mainly including pushing a large amount of information with personalized images, guiding public opinion through large-scale collaborative use, constructing war narratives with multiple themes, creating information fog by triggering tag war. It is believed that social robots will play an active role in cognitive domain confrontation activities such as seizing the discourse power of international communication, manipulating public opinion to cooperate with military action, maintaining ideological security, and relieving the mental stress of soldiers.
