Adaptive Controller and Observer for a Magnetic Microrobot [PDF]
IEEE Transactions on Robotics, 2013 This paper discusses the control design of a magnetically guided microrobotic system in blood vessels to perform minimally invasive medical procedures. Such microrobots consist of a polymer-bonded aggregate of nanosized ferromagnetic particles and a possible payload that can be propelled by the gradient coils of a magnetic device.

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.
