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.
