This paper describes traveling systems consisting of one major-wheel and three minor-wheels attached to each tip of three spokes. A link of inter-axle plays an important role of the system. It connects secondary axle to the major wheel axle. Its length is determined to ascend stably various stairs. The systems was designed to mount a cart for carrying agricultural products. The systems was applied to ascend stairs, travel on sand and cross a obstacle, despite of simple design.
