In this paper we consider efficiency of self-reproducing extraterrestrial Von-Neumann micro scale robots and analyse the observational characteristics. By examining the natural scenario of moving in the HII clouds, it has been found that the timescale of replication might be several years and even less – making the process of observation quite promising. We have shown that by encountering the interstellar protons the probes might be visible at least in the infrared energy band and the corresponding luminosities might reach enormous values.

关于星际冯诺依曼微型自我复制探测器

在本文中，我们考虑了自我复制的地外冯诺依曼微型机器人的效率，并分析了观测特征。通过检查在 HII 云中移动的自然场景，发现复制的时间尺度可能是几年甚至更短——这使得观察过程非常有希望。我们已经证明，通过遇到星际质子，探测器可能至少在红外能带中是可见的，并且相应的光度可能达到巨大的值。
