Abstract
A vehicle for traversing a surface using magnetic attachment is provided. The vehicle includes a chassis body and wheels attached to the chassis body. At least one magnetic module is attached via a resilient member to the chassis body. Each magnetic module includes a magnet and an offset member that provides an approximately constant offset between the surface and the magnet. The resilient member transfers a magnetic attractive force that is normal to the surface between the magnetic attracting module and the chassis body. The vehicle can traverse uneven surfaces without magnetically decoupling.
