Hydrogels, xerogels, and gel-derived soft composites systematically convert processing history into programmable mechanical function, governed by network elasticity, solvent transport, pore architecture, and structural anisotropy. This comprehensive review develops a rigorous, mechanics-first pathway that links material gel microstructure directly to the propulsion of magnetically driven soft robotic swimmers. Focus is placed on freeze-dried poly(vinyl alcohol) systems, nanocellulose-reinforced xerogels, biopolymer composites, and magnetically responsive networks, demonstrating how fabrication processing defines critical material signatures like broad relaxation spectra, transverse isotropy, and cyclic hysteresis. These complex physical attributes are characterized using finite-strain viscoelasticity, viscoplasticity, fractal rheology, damage mechanics, and coupled fluid–structure interactions. Crucially, geometric shape and actuation parameters are insufficient design variables; the body’s constitutive law fundamentally governs locomotive efficiency, magnetic loading protocols, and surrounding viscous flow fields. Ultimately, this work frames gel mechanics as a comprehensive design basis for soft robotics by explicitly mapping microstructural mechanics to swimmer-scale locomotion.
