Current interest in on-orbit servicing (OOS) is a strong motivation for advancing induction coupler technology. One of the fundamental technological use cases is that of a small inspection vehicle whose interactions with the target do not produce significant motion in that target—for example, an ISS inspection vehicle. Such a vehicle is primarily concerned with regulating planar motion along the surface of the target and stabilization of out-of-plane translation. This paper describes a study of how the planar component of that motion can be achieved with induction couplers.   \begin{figure}   \includegraphics{/figures/cart_on_track.png} \includegraphics{figures/iss_inspector.jpg}  \label{fig:issinspector}  \end{figure}
