Five-degree-of-freedom Manipulation of a Magnetic Capsule Endoscope in Fluid using a Single Permanent Magnet

Invention SummaryThis invention is a method to position and orient a magnetic capsule endoscope levitated in fluid, for use in endoscopy of the stomach, using a single permanent magnet whose position is controlled by a robotic manipulator outside of the patient’s body. The method is the first to enable five-degree-of-freedom manipulation of a...

A Singularity-free Mechanism for Orientation Control of a Permanent Magnet

Invention SummaryIt has been recently demonstrated that untethered magnetically actuated tools (MATs)—such as magnetic capsule endoscopes, magnetic swimming microrobots, and magnetic screws—can be actuated by a single rotating permanent magnet (RPM), whose position and orientation are controlled by a robotic manipulator, without constraining...
