随机定位机（RPM）是一种实验室仪器，用于提供相对于调节（生物）实验的重力矢量的方向的连续随机变化。当方向的变化快于物体对重力的反应时间时，RPM的使用可以产生与真正微重力效应相当的效应。因此，相对敏感的生物，如植物和其他系统，是RPM研究的绝佳候选者。本文将阐述其工作原理、技术和控制方式，并对以前使用和可用的实验系统进行概述。将讨论当前和未来的发展，如RPM上的显微镜设施或流体处理系统，以及提供模拟火星或月球重力的部分重力控制模式的选项。
A Random Positioning Machine (RPM) is a laboratory instrument to provide continuous random change in orientation relative to the gravity vector of an accommodated (biological) experiment. The use of the RPM can generate effects comparable to the effects of true microgravity when the changes in direction are faster than the object's response time to gravity. Thus, relatively responsive living objects, like plants but also other systems, are excellent candidates to be studied on RPMs. In this paper the working principle, technology and control modes will be explained and an overview of the previously used and available experiment systems will be presented. Current and future developments like a microscope facility or fluid handling systems on the RPM and the option to provide partial gravity control modes simulating for instance Mars or Moon gravity will be discussed.
