This literature review examines the impact of autonomous delivery robots (ADRs) on last-mile deliveries, their value to the logistics and transport industry, and their potential to create competitive business models. The review identifies four major themes: operations, infrastructure, regulations, and acceptance. ADRs can reduce costs, optimize time, and minimize externalities, but they face challenges in infrastructure, regulations, and societal acceptance. The review highlights the need for real-world case studies and implementations to address these challenges. Despite theoretical findings, practical implementation remains limited, and further research is needed to evaluate the full potential of ADRs in last-mile deliveries.This literature review examines the impact of autonomous delivery robots (ADRs) on last-mile deliveries, their value to the logistics and transport industry, and their potential to create competitive business models.
