Cost-effective space simulator Technical development and optimisation of an RPM prototype for series production

A Random Positioning Machine (RPM) is a device that continuously and randomly rotates objects in different spatial directions to create a simulated weightlessness.

This enables researchers to study the effects of on biological and physical systems without having to travel into space.

RPMs are often used in biology, materials science and space research.

RPM prototype

In a previous project as part of the PDP, low-cost RPMs (Random Positioning Machines) were developed, which were manufactured from commercially available and/or self-made parts. Initial tests have shown that these RPMs are very well suited as a didactic tool in teaching. However, in order to be able to use them widely in research and education, they need to be made available at a significantly lower cost

 


Aim of the work:


The aim of this thesis is to develop a kit for RPMs in higher quantities in order to promote and expand their use in research and teaching. The tasks include:

  • Reviewing and analysing the existing RPM prototypes
  • Revision and expansion of the catalogue of requirements for series production
  • Development of production-optimised designs that are cost-efficient and easy to manufacture
  • Analysing and evaluating the new designs in terms of their technical and economic feasibility
  • Carrying out suitable tests and prototyping processes to validate the new designs
  • Recommendation for the implementation of the optimised designs in series production
