Abstract: The traditional artificial intelligence of the unmanned system puts research focus on scientific discovery and technical implementation in the fields of human thought, perception and electromyographic response. The immune reaction is a unique physiological mechanism such that the organism could retain survival and health facing with the virus, germ and natural enemy. The so-called immune reaction inspires the unmanned system community, which includes the reaction including coping with the virus invading, the abrupt change of the environment, and the threatening of the natural enemy. In this paper, the survival problems of the unmanned system in the face of the attack, disturbance, jamming, blockade, damage, failure, and gaming are investigated. An universal framework of the immune intelligence of the unmanned system is established. In addition, the gap between the organism and the unmanned system is bridged. Considering the basic concept, reaction mechanism, key techniques and general framework, our paper puts research attention on the unmanned system. The problem is addressed from the perspectives of the perception and diagnosis, adaption and inspiration as well as learning and evolution. Finally, several possible future research directions of the immune intelligence techniques are provided.
