摘　　要：在偏远、危险地区,机器人可感知环境、智能交互,协同完成复杂任务。以卫星和无人机为主体的天空地协同网络能够为这些机器人提供全域泛在、随遇接入的通信服务。首先,分析无人作业发展趋势和机器人通信需求。基于此,面向机器人通信的特点,建议跳出“信息传输管道”的传统视角,在支持信息传输的同时,关注信息的内容和价值。进一步综合考虑机器人通信中信息生成的动作及其反馈,提出潜在技术变革的切入点。具体地,从结构化通信资源配置、机器人行为调控和感-传-算-控闭环模型三个方面阐述维纳控制论启发的通信范式变革途径。In remote and hazardous areas,robots are capable of environmental perception,intelligent interaction,and collaborative completion of complex tasks.Space-air-ground integrated networks,primarily composed of satellites and unmanned aerial vehicles,can provide these robots with ubiquitous and on-demand communication services.Initially,this paper analyzes the development trends and communication requirements of unmanned operations.Based on this analysis,and given the characteristics of robot communication,it is suggested to move beyond the traditional perspective of viewing communication as merely an"information transmission pipeline",to also focus on the content and value of the information.Further considering the actions associated with information generation in robot communication and their feedback,potential entry points for technological transformation are proposed.Specifically,the paper elucidates communication paradigm shifts inspired by Wiener's cybernetics,from three aspects:structured communication resource allocation,robot behavior regulation,and the closed-loop model of sensing-transmiting-computing-controlling.
