Magnetic-Field-Inspired Navigation for Quadcopter Robot in Unknown Environments [PDF]
2019 International Conference on Robotics and Automation (ICRA), 2019 In this paper, a magnetic-field-inspired robot navigation is used to navigate an under-actuated quad-copter towards the desired position amidst previously-unknown arbitrary-shaped convex obstacles. Taking inspiration from the phenomena of magnetic field interaction with charged particles observed in nature, the algorithm outperforms previous reactive ...

Navigation of a magnetic micro-robot through a cerebral aneurysm phantom with magnetic particle imaging [PDF]
Scientific Reports, 2021 AbstractCerebral aneurysms are potentially life threatening and nowadays treated by a catheter-guided coiling or by a neurosurgical clipping intervention. Here, we propose a helically shaped magnetic micro-robot, which can be steered by magnetic fields in an untethered manner and could be applied for a novel coiling procedure.
