Untethered Magnetic Robots (UMRs) are small, screw-shaped devices that can be wirelessly actuated. The helical structure of the UMR facilitates propulsion and tissue entry capabilities. UMRs are actuated by a rotating magnetic field using a Rotating Permanent Magnet (RPM). However, operating multiple UMRs in close proximity introduces challenges for their control, as they react simultaneously to the actuating magnetic field.
In this presentation, I will present a method to possibly overcome this problem. Distance-based step-out frequency control can be a first step towards the implementation of multiple UMRs in a clinical setting.
