近幾年人工智慧的發展和應用，推動了人形機器人的發展，讓我們得以在日常生活中與人形機器人近距離接觸。本研究希望能填補在人機傳播視角下，人與人形機器人的研究空白。從人機傳播及媒介物質性的角度切入，以軟銀公司的機器人 Pepper 為個案研究，通過對科技公司人員的訪談，並且實地觀察人類與 Pepper 的互動情形主要發現：一，人形機器人之所以能夠與人類互動，是它實現了擬人化的表演，而科技公司扮演重要推手；二，人形機器人執行任務是因果線性的時間順序，人與人的互動卻充滿變動性，過往適用於人際傳播的理論無法完全適用於人機傳播；三，人形機器人的物質性使得人形機器人不僅僅是被人類使用的工具，物質性在一定程度上共構出人與人形機器人的關係。

 In recent years, the development and application of Artificial Intelligence has promoted the development of humanoid robots with which we can have close contact in our daily lives. This study aims to bridge the research gap between humans and humanoid robots from the perspective of human-machine communication. The study uses SoftBank's robot Pepper as a case study from the perspective of Human-Machine Communication and the materiality of the media, and observes the interaction between humans and Pepper in the field through interviews with employees of the technology company. The study finds that, first the humanoid robot Pepper performs tasks in a linear temporal sequence of cause and effect, while human-human interaction is full of variability and theories previously applied to interpersonal communication cannot be fully applied to human-machine communication; second, the materiality of the humanoid robot Pepper makes the humanoid robot more than a tool used by humans, and materiality shapes the relationship between humans and humanoid robots to some extent.
