µWheel translation on inclines. (a) µWheel angular velocity (\(\omega\)) as a function of size (\(R\)) and incline angle (\(\upphi\)). Dotted line shows the \(\omega \propto 1/R\) scaling. (inset) Translating µwheel on an incline. (b) µWheel velocity over incline angles 0–80° with solid lines the variable gap width model (Supplementary Equation 1). All µwheels were propelled with a constant 40 Hz circular rotating field of magnitude 3.7 mT and 30° camber angle (θ).
