Robot technology is expected to be applied to provide various services in homes, stores, public facilities and so on. However, if we just talk about homes, different homes have different layouts and require different services, which is a major factor increasing cost and technical issues. In contrast, convenience stores provide services with huge networks of chain stores all over Japan. The store environments and services are standardized, so the problems mentioned above do not apply. On the other hand, it is a labor-intensive industry where store clerks do many tasks, so automation by robot technology is expected to bring huge benefits. At the same time, it is expected that technology will allow the creation of new services that were previously difficult to provide.
