Resonant electromagnetic navigation systems generate controllable oscillating and rotating magnetic fields using resonant electronic networks. This modality holds great potential to control untethered magnetic robots remotely for medical applications using fast rotating magnetic fields. However, the
Magnetic helical microrobots driven by low-strength rotating magnetic fields have found wide applications, particularly in biomedical research. The motion dynamics of magnetic helical microrobots is critical for their intelligent control and for performing tasks in complex environments. These micror
Variable stiffness catheters typically rely on thermally induced stiffness transitions with a transition temperature above body temperature. This imposes considerable safety limitations for medical applications. In this work, we present a variable stiffness catheter using a hybrid control strategy c…
Small-scale robots with soft joints and hinges have recently attracted interest because these components allow for more sophisticated locomotion mechanisms. Here, we investigate two different types of nanoscale swimmers as depicted in Figure 1. One consists of a rigid magnetic head linked to a semi-…
Digital holography is used to track the three-dimensional position of a magnetic microrobot maneuvered in real time by means of an electromagnetic manipulation system. The method presented is able to process holograms at 40 Hz with a position accuracy in the imaging plane and in depth of <inline-for
Shape shifting soft microrobots are generated from self-folding hydrogel bilayer structures. The folding conditions are analyzed to develop an optimal strategy for producing desired three-dimensional shapes. We present two different methods for programming magnetization in these microrobots that are
