Magnetic Mapping for Robot Navigation in Indoor Environments [PDF]

2021 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2021
Localization has always been one of the fundamental problems in the field of robotic navigation. The emergence of GPS came as a solution for localization systems in outdoor environments. However, the accuracy of GPS is not always sufficient and GPS based systems often fail and are not suited for indoor environments.

Improved procedural efficiency of atrial fibrillation ablation using robotic magnetic navigation

Heart Rhythm O2
BACKGROUND: Currently, there is still a large variability in procedural efficiency of atrial fibrillation (AF) ablation. OBJECTIVE: This study aimed to evaluate the evolution of procedural efficiency of AF ablation using robotic magnetic navigation (RMN) and compare the most efficient approach with cryoballoon ablation (CRYO), a typical “single-shot ...

Endovascular Magnetically Guided Robots: Navigation Modeling and Optimization [PDF]

IEEE Transactions on Biomedical Engineering, 2012
This paper deals with the benefits of using a nonlinear model-based approach for controlling magnetically guided therapeutic microrobots in the cardiovascular system. Such robots used for minimally invasive interventions consist of a polymer binded aggregate of nanosized ferromagnetic particles functionalized by drug-conjugated micelles.

Magnetic Resonance Imaging-Based Tracking and Navigation of Submillimeter-Scale Wireless Magnetic Robots

Advanced Intelligent Systems, 2021
Magnetic resonance imaging (MRI) scanners have recently been used for magnetic actuation of robots for minimally invasive medical operations. Due to MRI's high soft-tissue selectivity, it is possible to obtain 3D images of hard-to-reach cavities in the human body, where the wireless miniature magnetic robots powered by MRI could be employed for high ...

Robotic Magnetic Navigation for Atrial Fibrillation Ablation

Journal of the American College of Cardiology, 2006
We assessed feasibility of magnetic catheter guidance in patients with atrial fibrillation (AF) undergoing circumferential pulmonary vein ablation (CPVA).No data are available on feasibility of remote navigation for AF ablation.Forty patients underwent CPVA for symptomatic AF using the NIOBE II remote magnetic system (Stereotaxis Inc., St.

Magnetic strips as landmarks for mobile robot navigation [PDF]

2016 International Conference on Applied Electronics (AE), 2016
In this paper, a low-cost localization system designed for mobile robots is introduced. The system has been developed for a teaching aid where a mobile robot operates in a maze. The mobile robot is navigated by a high level control system where path-planning is executed; however, autonomous execution of the plan is required from the robot.
