Resumen

The study of living organisms and various materials under microgravity conditions is crucial for advancing space technology and scientific research. However, conducting such studies in space is highly expensive, with costs reaching approximately $80,000 per kilogram, excluding experimental development expenses. To overcome this financial challenge, it is essential to develop alternative methods for simulating microgravity on Earth. This paper presents the design and development of a Random Motion Machine (RMM) based on a three-dimensional clinostat to replicate microgravity conditions in a terrestrial environment. The system utilizes two rotational axes with variable speeds ranging from 20 to 90 revolutions per minute, creating continuous random motion. The working area of 20 x 20 x 20 cm3 enables the testing of biological samples, materials, and small experimental setups under simulated microgravity. The proposed RMM provides a cost-effective and accessible platform for conducting microgravity research, supporting advancements in space exploration, biotechnology, and material sciences. This system facilitates experimental studies without requiring spaceflight, offering valuable insights into the behavior of biological and physical systems under reduced gravitational influence.
