An autonomous vehicle assembly comprises a chassis assembly and a storage assembly. The chassis assembly includes a front chassis module and a rear chassis module that are selectively connectable to one another. The front chassis module includes a front wheel and an EBS assembly for steering the front wheel and the rear chassis module includes a rear wheel and a propulsion assembly for driving the rear wheel. An autonomous driving module is selectively connected to the chassis assembly and independently in communication with the EBS assembly and the propulsion assembly.
