Simulation and machine-learning-based analysis of active Brownian magnetic microswimmers — •Anas Hussin, Sascha Lambert, and Stefan Klumpp — Institute for the Dynamics of Complex Systems, University of Göttingen, Göttingen

Magnetic microswimmers, whether these are biological organisms or designed nanomachines, show promise in biomedical microrobotics, as they can be steered remotely with a magnetic field. Often, these swimmers encounter complex environments characterized by obstacles and confinement. To understand their navigation in such complex environment, we simulate their swimming as active Brownian particles with an intrinsic magnetic moment and interactions with obstacles and walls that can be of hydrodynamic and/or steric nature. In addition, we use the resulting trajectories to train a neural network with an optimized architecture in order to explore the ability of machine learning algorithms to infer parameters of the motion from trajectories.
