20090044990 | Screw driven mobile base - The present invention is a screw driven, mobile base for traversing a wide range of outdoor soft or rough surfaces and terrains. The device has three degrees of freedom in a plane and, thus, is highly maneuverable, able to travel in any horizontal direction relative to its orientation and able to orient itself independently of the direction of travel. Each screw comprises a structural core with an outer helical edge profile of curved cross-section, having an abrasion resistant, low friction material on the outer surface. The device rides on the low friction profiles and relies on the combined effects of the multiple drive screws against the ground surface. The drive screw axes are non-parallel in most of the configurations. | 02-19-2009 |
