Drones with propulsions systems supported in a housing are provided where the orientation of the housing is independent from the orientation of the propulsion system. Drones are provided where a propulsion system is rotatable about a first axis and a second axis that is perpendicular to the first axis, permitting the propulsion system to assume substantially any position with a sphere. Drones are provided where a bladeless inner tube is rotatable about a first axis and a second axis that is perpendicular to the first axis, permitting the inner tube to assume substantially any position within a sphere. Drone systems are provided with connectable unit drones. An unmanned land vehicle is provided having a wheel assembly that is rotatable about a first axis and a second axis that is perpendicular to the first axis, permitting the wheel assembly to assume substantially any position with a sphere.

An unmanned conveying system includes: plural unmanned conveying vehicles that can convey cargo; a cargo priority order deciding section that decides upon a priority order in which the cargo are to be conveyed, in accordance with conditions of the cargo; and a traveling route setting section that decides upon traveling routes of the unmanned conveying vehicles on the basis of the priority order.

A vehicle auxiliary control apparatus includes: an auxiliary steering assembly, including: a frame; an auxiliary steering shaft mounted for rotation in the frame; an auxiliary steering wheel mounted to the auxiliary steering shaft; first and second cable spool assemblies mounted to the auxiliary steering shaft; and first and second cable assemblies coupled to the first and second cable spool assemblies, respectively; and coupling means for coupling the first and second cable assemblies to a stock steering shaft of a motor vehicle, such that rotation of the auxiliary steering shaft causes rotation of the motor vehicle steering shaft.

The present invention relates to a novel robot drive train that is robust, and low cost. The drive train is capable of ascending obstacles greater than the height of its wheels, protects the robot against shocks/vibration, and is highly maneuverable, such as able to execute a zero-point turn. To control the bogie in a variety of scenarios, a novel mechanism is used to selectively limit the articulation range of the bogie and/or programmatically apply a preload to the bogie axle.

A motor vehicle drive-axle includes a drive-axle housing defining a gear-set cavity and a shaft bore having first and second bearing pockets and an oil cavity arranged between the first and second bearing pockets. The housing also defines a supply channel and a return passage configured to respectively supply oil from the gear-set cavity to the oil cavity and return oil from the oil cavity to the gear-set cavity. The housing also includes an input shaft extending through the shaft bore into the differential gear-set cavity. The housing additionally includes first and second bearings arranged within respective first and second bearing pockets for supporting the input shaft. The housing additionally includes a lubrication regulating insert arranged inside the oil cavity. The insert defines first and second lubrication channels configured to direct oil from the supply passage to respective first and second bearings.
