... modeling results. Furthermore, we find that both excessively low and high robot heights hinder walking speed: lower heights reduce surface friction, while higher heights compromise agility. This comprehensive optimization strategy advances the capabilities of small-scale soft magnetic robots. Our work...

... separation of the particles from a non-magnetic liquid medium such as blood in the human body. A two-dimensional model, which represents a slice through the center of a spherical particle in a fluid, is proposed in this study, and only the magnetic force and the drag force are taken into consideration...
