Research Question: What factors influence the distribution and retention of Untethered Magnetic Robots (UMRs) within an aneurysm during sequential deployments, and how can control techniques be adapted to address these factors effectively while ensuring the reliable guidance of UMRs to the aneurysm?
Hypothesis: If the motion and distribution of multiple small UMRs inside blood vessels can be effectively controlled through an external magnetic field, then it is possible to fill the aneurysm reliably, provided that the magnetic field can retain the UMRs within the target area.
