There are a few parts that can be enhanced with current autonomous delivery vehicles; i.e) fixed delivery space, design, and interaction. Fixed space lowers the space efficiency. Therefore mostly used for food deliveries. The design of the vehicle evokes a car with bulky sensors displeasingly. Physical interaction between the vehicle and humans is banned. ROBO A2Z is an innovation to the current autonomous delivery vehicle, designed as an art object inspired by quadruped animals. Its DIY-able modular interior system maximises the space efficiency without the bulkiness while directly interacting with humans. Another level of benefits to all.
