Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue. [PDF]
Adv Sci (Weinh)This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...

Permanent magnetic droplet–derived microrobots
Science AdvancesMicrorobots hold substantial potential for precision medicine. However, challenges remain in balancing multifunctional cargo loading with efficient locomotion and in predicting behavior in complex biological environments. Here, we present permanent magnetic droplet–derived microrobots (PMDMs) with superior cargo loading capacity and dynamic locomotion ...

Collaborative Magnetic Agents for 3D Microrobotic Grasping
Advanced Intelligent Systems, 2023 Untethered microrobotic grasping has enabled the precise manipulation of small components in difficult‐to‐reach environments. However, the fabrication of deformable grasping robots at small scales requires advanced materials and fabrication technologies. Alternatively, multiple microrobots can be used to surround and grasp objects.
