Different strategies of navigation in heterogeneous magnetic fields are investigated using natural and synthetic autonomously moving micro- and nanonavigators on top of a magnetic garnet film with uniaxial anisotropy creating a dense stripe domain structure. The use of ferromagnetic navigators leads to dynamic frustration, but synergy is achieved between the autonomous motion and magnetic orientation of paramagnetic navigators. The use of differently magnetized ferromagnetic and paramagnetic nanonavigators enables one to change from a roving to a guided motion. These different modes of motion can be utilized for distinct processes, such as the delivery and distribution of molecular cargo attached to synthetic navigators.
