协作式无人系统以其灵活高效和内在抗毁的优势，已成为应对众多重大挑战的关键手段。尤其是借助人工智能（AI）的具象实现，无人系统达到了越来越高的集群自主水平。然而，目前的网联协作式无人系统主要是为狭窄的特定领域任务而设计并只适用于这些任务。面对我们生活中具有挑战性的任务，无人系
统仍不能以匹配人类智能水平的方式来充分满足人类的需求。我们在本文中提出了一个以人为本的网联无人系统的愿景——无人智群（unmanned intelligent cluster, UnIC）。在这个愿景中，分布式无人系统和人通过知识共享和社会意识连接起来，以实现协作认知。本文详细介绍了UnIC 的概念、智能的来源、智
群的分层结构，并综述了实现这一愿景的使能技术。除了技术方面，本文也从一般意义上关注了无人系统的社会接受问题。

Collaborative unmanned systems have emerged to meet our society's wide-ranging grand challenges, with their advantages including high performance, efficiency, flexibility, and inherent resilience. Increasing levels of group/team autonomy have also been achieved due to the embodiment of artificial intelligence (AI). However, the current networked unmanned systems still do not have sufficient human-level intelligence and human needs fulfillment for the challenging missions in our lives. We propose in this paper a vision of human-centric networked unmanned systems: Unmanned Intelligent Clusters (UnIC). Within this vision, distributed unmanned systems and humans are connected via knowledge to achieve cognition. This paper details UnIC's concept, sources of intelligence, and layered architecture, and review enabling technologies for achieving this vision. In addition to the technological aspects, the social acceptance is highlighted.
