Taiwan is rapidly entering a super-aged society, where traditional care models face significant challenges, including labor shortages and high costs. There is an urgent need for innovative smart care solutions. However, most existing care robots remain limited to single tasks and lack cross-modal perception, natural interaction, and multi-functional integration, restricting their practical deployment. Although generative AI, large-language models, and multimodal sensing technologies have advanced rapidly in recent years, a critical technical gap remains: how to deeply integrate Physical AI into care robots. In response, this project proposes a home healthcare robot for the elderly, centered around a multimodal large-language model. The goal is to develop key Physical AI technologies focused on traditional Chinese applications, and creating an intelligent healthcare robot that has both mobility, sovereignty and trustworthiness to realize a feasible home healthcare solution.
