The carrying device further includes a support arm coupled to and extending outwardly from the second end of the base. The support arm is configured to support the at least one article when the at least one article is retained on the carrying surface at a position proximate to the second end of the base.

A parcel cart for transporting parcels comprises a substructure, with a frame mounted to and supported by the substructure. The frame defines an internal volume in which parcels are received and stored for transport. The frame also includes: a base; a first end wall; a second end wall; a first side wall; and a second side wall. To facilitate loading or unloading of the parcel cart, the frame can include at least one end wall configured to transition between an upright position and a lowered position. To facilitate autonomous transport of the parcel cart, the substructure and the frame can define a cavity for receiving a mobile robot. To avoid occlusion of the field of view of one or more cameras associated with the mobile robot, the frame can include at least one end wall that is in a non-perpendicular orientation relative to the base.

A foldable cart having a first lower cargo compartment and a second upper cargo compartment vertically aligned over the lower cargo compartment, a front wall, a rear wall, a left wall, a right wall, a lower compartment floor, and an upper compartment floor, the upper compartment floor forming a ceiling for the lower compartment; at least one pair of rear-mounted wheels and one pair of front-mounted wheels, at least one of the pairs of wheels mounted on an axle; swivel connectors for attaching each of the front wheels to the lower compartment floor; a handle; and a locking mechanism for securely closing one or more of the compartments.

A trailer dolly can include various features to be adjustable between a manual configuration and a vehicular towing configuration. In the manual configuration, a user can manually maneuver the trailer dolly to position the trailer, such as by using one or more retractable handles. Where the user desires to maneuver the trailer with a vehicle, the trailer dolly can be adjusted to the vehicle towing configuration. In an example, the trailer dolly can be coupled to the vehicle with a second hitch attached to the trailer dolly, the second hitch located distally along the tow bar with respect to the trailer hitch supporting the trailer load. Accordingly, the trailer dolly can be used for both manual and vehicular applications and the user can transition between the manual and vehicular configurations while the trailer is hitched to the trailer dolly.
