Provided are multi-tread vehicles and methods of operating such vehicles to access small interior spaces. A multi-tread vehicle may include two or more tread sections such that each pair of adjacent tread sections is interconnected by a connector section. Furthermore, each pair may have one or more degrees of articulations, such as being pivotable with respect to each other around one or more axis and/or being bendable with respect to each other around one or more axis. These articulation degrees may be provided by the connector section and/or by couplings between the connector section and each tread section. In some embodiments, each tread section may include two portions detachably coupled to each other. This detachable coupling may be used for disassembly of the multi-tread vehicle after or even during its use, for example, when only a portion of the vehicle needs to be retrieved from an interior space.

A motorcycle towing hitch 20 includes a receiver 22 to which is attached a lift system 24. The lift system 24 is operable to raise and lower a cradle 26 which receives the front wheel 30 of a motorcycle 32 to hold the front wheel captive in the cradle. The cradle 26 is hinged relative to the lift system to be rotatable about an upright axis 28, for instance, when towing the motorcycle around a corner. A restraint system 34 is provided for preventing the handlebars of the motorcycle to rotate relative to the motorcycle frame. In this manner, when the motorcycle is towed around a corner, the motorcycle frame does not tilt downwardly into the corner as would be the case if the motorcycle frame were permitted to rotate relative to the motorcycle handlebars when negotiating a corner.

A computing system for an autonomous engine module stores a self-driving capability and is configured to determine, by communication between an autonomous engine module in which the computing system resides and other autonomous engine modules, and responsive to a user request for use of an autonomous engine module, at least one suitable autonomous engine module use candidate. The computing system may also generate a notification directed to the user including information relating to the at least one suitable autonomous engine module use candidate. The computing system may also receive a selection by the user of an autonomous engine module use candidate. The computing system may also, using the self-driving capability, autonomously drive the autonomous engine module to a designated pickup location responsive to selection by the user of the autonomous engine module as the autonomous engine module use candidate.

A conveying device according to the present invention includes a first connection mechanism provided on an upper surface, a base member provided on the upper surface, a sliding mechanism that relatively and slidably moves a position of the first connection mechanism on a slide axis relative to the base member, and a traveling mechanism that makes the conveying device travel. The first connection mechanism is connected with a carriage at a predetermined connection position. The sliding mechanism slidably moves the first connection mechanism between the connection position and a predetermined conveyance position spaced away from the connection position on the slide axis in a state in which the first connection mechanism is connected with the carriage. The traveling mechanism makes the conveying device travel in a state in which the first connection mechanism is positioned in the conveyance position.
