COSI Measure is an open source multipurpose 3-axis robot operating in a large volume, that can be equipped with e.g. field mapping probes for static or dynamic field measurements (electromagnetic, temperature etc.). Submillimeter fidelity and reproducibility/backlash performance were evaluated experimentally. It can be potentially upgraded to be used as a CNC, for 3D printing or other applications, that require reproducible submillimeter movements.
