A Physics-Informed Neural Network for the Calibration of Electromagnetic Navigation Systems

Pascal Ernst, Simone Gervasoni, Derick Sivakumaran, Enea Masina, David F. Sargent, Bradley J. Nelson +1

IROS 2025

Electromagnetic Navigation Systems enable remote actuation of untethered micro and nanorobots, as well as the precise control of magnetic surgical tools for minimally invasive medical procedures. Accurate modeling of the magnetic fields generated by the electromagnets composing these systems is esse

Automated Particle Collection for Protein Crystal Harvesting

Burak Zeydan, Andrew J. Petruska, Luca Somm, Roel Pieters, Yang Fang, David F. Sargent +1

RA-L 2017

A robust automated system to collect protein crystals for X-ray crystallography is presented. This system uses an ultraviolet imaging system based on commercial off-the-shelf components, a magnetically manipulated tool, and a resilient behavior-based controller. The system is validated by collecting

RodBot: A rolling microrobot for micromanipulation

Roel Pieters, Hsi-Wen Tung, Samuel Charreyron, David F. Sargent, Bradley J. Nelson

ICRA 2015poster

We introduce the modelling and control of a rolling microrobot. The microrobot is capable of manipulating micro-objects through the use of a magnetic visual control system. This system consists of a rod-shaped microrobot, a magnetic actuation system and a visual control system. Motion of the rolling…
