Abstract: A method for operating a device ascending or descending stairs. The device has a plurality of wheels rotatable about axes that are fixed with respect to a cluster arm, where the cluster arm itself is rotated about an axis so that wheels rest on successive stairs. The wheels and cluster arms are controlled according to separate control laws by a controller. Whether the device ascends or descends the stairs is governed by the pitch of the device relative to specified front and rear angles.
