The present disclosure is directed to commercial vehicle loading and unloading systems, and associated systems, devices, and methods. In one embodiment, a cargo loading and unloading system includes a cargo loading and unloading assembly and/or a cargo repositioning system. The assembly includes a first mechanical arm and a second mechanical arm that are mountable at opposite sides of an opening of the trailer. Each mechanical arm includes a first portion and a second portion pivotally coupled to the first portion. The first portions are configured to vertically raise and lower the second portions and move the second portions laterally along the opening of the trailer. The second portions include rollers and are configured to support cargo on the rollers as the mechanical arms are used to hold the cargo off the ground, and to selectively convey the cargo at least partially into or out of the trailer via the rollers.

Methods and software for setting parameters for operating a modular robot are disclosed. One method includes receiving, by a server, communications data from a controller of the modular robot. The modular robot has storage for storing program instructions for executing autonomous movement at a location. The method includes sending, by the server, an initial outline for the controller to generate calibrated mapping data for the location. The calibrated mapping data identifies an outline at the location. The method includes sending, by the server, identification of at least two zones at the location, where the at least two zones define different areas at the location. The controller of the modular robot is configured to use the calibrated mapping data for said autonomous movement at the location and the controller is configured to operate a respective work function in each of the at least two zones.

A ramp-equipped vehicle includes: a vehicle-height adjusting mechanism configured to adjust a vehicle height of a vehicle; a ramp configured to be movable between a deployed state and a stored state, the deployed state being a state where the ramp protrudes outwardly from the vehicle, the stored state being a state where the ramp is stored inside the vehicle; and a camera configured to detect a person coming closer to the vehicle. When the camera detects a person coming closer to a doorway of the vehicle during vehicle height adjustment by the vehicle-height adjusting mechanism, the vehicle height adjustment by the vehicle-height adjusting mechanism is interrupted.

In one example, a mother cart is provided that is suitable for transporting a daughter cart. The mother cart includes a lower frame, an upper frame connected to the lower frame, and the lower frame includes wheels configured to allow the mother cart to be moved. The lower frame also includes support guides configured to support the daughter cart in a raised position to provide a predetermined ground clearance, and the lower frame has two open sides so as to provide for two-way loading and unloading of the daughter cart on the mother cart.

In one embodiment, a truck trailer has a cargo container that defines a cargo area therein. The trailer has a rear cargo lift having a platform disposed within the cargo area at a rear end of the trailer. The platform is vertically movable between a floor of the trailer and a first elevation that is above the floor. The trailer has an upper cargo deck supported within a portion of the cargo area that is between the rear lift and a front end of the trailer. The upper cargo deck divides the portion of the cargo area into upper and lower areas. The upper cargo deck can align with the rear cargo lift at the first elevation so as to receive cargo into the upper area, and translate the cargo to a second elevation that is above the first elevation so as to receive cargo in the lower area.

A multi-functional cargo transfer vehicle and method. The multi-functional cargo transfer vehicle comprises a vehicle body, a cargo conveying rack, a lifting mechanism, and a control system; the vehicle body is located below for providing a platform and support; the cargo conveying rack is located above the vehicle body and includes a plurality of layers for loading and unloading cargoes; the lifting mechanism is located on the outer side of the cargo conveying rack for lifting the cargo conveying rack; the control system is located on the vehicle body for controlling omni-directional driving, accurate butt joint, and automatic loading and unloading of the multi-functional cargo transfer vehicle. Accordingly, a multi-functional cargo transfer vehicle is adopted such that the multi-task functions of loading and unloading, transporting, and conveying of cargoes are simultaneously realized, thereby efficiently completing the transferring process of cargoes from a storage place to a transporting carrier.
