Abstract	In viscous fluids, motile microentities such as bacteriaor artificialswimmers often display different transport modes than macroscopicones. A current challenge in the field aims at using friction asymmetryto steer the motion of microscopic particles. Here we show that lithographicallyshaped magnetic microtriangles undergo a series of complex transportmodes when driven by a precessing magnetic field, including a surfing-likedrift close to the bottom plane. In this regime, we exploit the triangleasymmetric shape to obtain a transversal drift which is later usedto transport the microtriangle in any direction along the plane. Weexplain this friction-induced anisotropic sliding with a minimal numericalmodel capable to reproduce the experimental results. Due to the flexibilityoffered by soft-lithographic sculpturing, our method to guide anisotropic-shapedmagnetic microcomposites can be potentially extended to many otherfield responsive structures operating in fluid media.
