A roller assembly includes at least one roller, an L-shaped board and at least one L-shaped fixing member. The L-shaped fixing member is fixed on the L-shaped board; and the roller is fixed and connected on the L-shaped board through the L-shaped fixing member. A package includes a box and the roller assembly. The box contains at least one hole and the roller protrudes from the hole. Further, the package is used as follows. The box is opened and the matter to be packaged is put into the box. Then the roller assembly is placed into the box, and the roller assembly is sandwiched between the box and the matter. Next, the roller(s) is aligned with the hole(s). Subsequently, the box and the matter are compressed to make the roller(s) protrude from the hole(s). Finally, the box are sealed from the bottom surface to complete the package.

To avoid or reduce the necessity of loading a cargo container on a container carrying vehicle, for example, a cargo container 100 includes: engaging portions 101b disposed at four corners of each of upper and lower surfaces of a shell 101 and each engageable with a spreader of a container crane; and a wheel 113 capable of supporting the cargo container 100 such that the cargo container 100 is allowed to run. The wheel 113 is switchable between a runnable state where at least a lowermost portion is located below a bottom surface 101c of the cargo container 100 and supports the cargo container 100 such that the cargo container 100 is allowed to run, and a loaded state where the wheel 113 moves inward from the bottom surface 101c and the bottom surface 101c is allowed to make contact with a mount surface of the cargo container 100.

A modular autonomous bot apparatus assembly is described for transporting an item being shipped. The assembly includes a modular mobility base having propulsion, steering, sensors for collision avoidance, and suspension actuators; a modular auxiliary power module with a power source and cargo door; a modular cargo storage system with folding structural walls and a latching system; and a modular mobile autonomy module that covers the cargo storage system and provides human interaction interfaces, externals sensors, a wireless interface, and an autonomous controller with interfacing circuitry coupled to the human interaction interfaces and sensors on the mobile autonomy module. The assembly has a power and data transport bus that provides a communication and power conduit across the different modular components. A method for on-demand assembly of such a bot apparatus is further described with steps for authenticating the different modular components during assembly.

A modular portable storage container system includes a storage container having first and second sections. The first section defines a first partial volume of storage space and the second section defines a second partial volume of storage space. The system further includes a lock mechanism with a lock arm, lock handle, and pivot shaft defining an axis of rotation. The lock arm and handle are fixed for common rotation with the pivot shaft. The arm extends radially outward from the pivot shaft to a roller assembly. A lock track is disposed within the second section and extends from a fluted open portion to a closed end, with a continuous track portion disposed therebetween. The first and second sections are movable between at least closed and open positions. In the closed position, the roller assembly engages with the lock track and retains the first section in contact with the second portion.
