    Abstract: A person support apparatus comprises a lower frame, an upper frame, a drive structure, and a control system. The upper frame is movably supported above the lower frame. The drive structure is coupled to the upper frame and configured to selectively engage a surface to, when activated, propel the person support apparatus along the surface. The control system is configured to determine an engagement status of the drive structure with the surface and trigger a response based on the engagement status.
