A system comprising:

• at least one delivery vehicle, each comprising:
• a respective vehicle body, the vehicle body comprising a bay therein;
• a respective plurality of container hangers mounted within the bay;
• a respective unloading arm movable between a retracted arm position and an extended arm position, the unloading arm being at least partially received in the bay in the retracted arm position and extending from the vehicle body in the extended arm position, wherein the unloading arm comprises at least one container carrying member longitudinally movable along the unloading arm for selective longitudinal alignment with each of the plurality of container hangers, and wherein the unloading arm is pivotably connected to the vehicle body of the vehicle and rotates about a pivot axis between the retracted arm position and the extended arm position, and the unloading arm rotates in a vertical plane between the retracted arm position and the extended arm position;
• and
• at least one remote computing device in communication with the at least one vehicle, wherein the at least one remote computing device sends signals to the vehicle to control at least one of navigation and unloading of the vehicle.

A method for a delivery vehicle comprising a vehicle body and a bay within the body, the method comprising:
