“Transporting things” is a basic economic activity, and logistics is sometimes known as the physical internet since it is so closely related to infrastructure. However, with the decrease in the working-age population and the increase in delivery volume, the load placed on the sites at the end of the supply chain has become extremely high. This paper discusses the development, demonstration, and practical application of indoor delivery robots, which are expected to play an active role in solving these social issues, and outdoor delivery robots, which have been attracting attention in recent years, especially on public roads. We will also introduce the benefits to stakeholders and the attainment of social acceptance, which are necessary for continuous business as a transportation solution.
