An ATV is shown having a steering system comprised of a power steering unit having drive and driven pitman arms coupled to a drag link. The drive pitman arm is laterally offset from a vehicle centerline and is driven by the power steering unit. An alternate power steering system includes a pack and pinion subassembly coupled to a power steering motor, which then couples to steering arms of the ATV.

A self-propelled device includes a spherical housing and an internal drive system. The self-propelled device can further include an internal structure having a magnet holder that holds a first set of magnets and an external accessory comprising a second set of magnets to magnetically interact, through the spherical housing, with the first set magnets

A moving body includes a frame, a pair of right and left first wheels, a pair of right and left second wheels, a pair of right and left first parallel links connecting the first wheels and the second wheels, and a second parallel link connecting the pair of right and left first parallel links. Furthermore, a height changing unit connects the second parallel link and the frame and changes a position of the frame in a height direction with respect to the second parallel link, and a controller controls the height changing unit so as to maintain a height of the frame from a road surface.

The assembled-type traveling carriage includes: the telescopic cylindrical body being an extendable telescopic cylindrical body rotatably provided with a first screw at each end thereof, and incorporating an actuator configured to extend and withdraw a nest; a joint block provided with a second screw; a traveler rotatably provided with the first screw and attached a driving device thereto; and a coupling rod rotatably provided with the first screw on each end thereof. A first planar frame body is assembled by screwing joint blocks to four of the telescopic cylindrical bodies, screwing the travelers to the joint blocks such that the travelers are positioned on extension lines of the telescopic cylindrical bodies, and coupling one ends of the four telescopic cylindrical bodies to one another by the coupling rods through the joint blocks.

An engine airflow adjustment system that includes an engine that powers operation of a vehicle. A fan drives an airflow over the engine to convectively cool the engine. A funnel receives a portion of the airflow from the fan and directs the airflow to a specific location on the engine to blow debris off of the engine.
