Background: Random positioning machine (RPM) is a very effective device that can be used for space experiments on Earth. RPM had been constructed and verified for its ability to simulate microgravity conditions. This study was done to construct the RPM and to evaluate the growth pattern of Brasica on RPM. Methods: 2d clinostat was constructed and Arabidopsises were grown on it for 2 weeks. The experiment group on 2d clinostat was compared with the control group on Earth. RPM has been designed, constructed and checked for its ability to simulate microgravity conditions in the Seoul National University College of Medicine. Brasicas were grown for 72 hours both on RPM and on Earth and their growth patterns were compared. Results: RPM had operated in normal conditions without any significant failures. To verify the microgravity conditions, the summation of gravity vectors on the sample stage were depicted on a graph and also calculated by time. Each point of gravity vectors became an entire globe shape and the cumulated summation of gravity vectors decreased below 10<SUP>-3</SUP> g. Conclusion: RPM was successfully constructed in Korea and automorphogenesis of Brasica was observed during their growth on RPM like space. Diverse experiments with plants and animal cells will be possible in the future on RPM.
