目前的陪伴機器人大多為寵物型態或是針對老年人或障礙者的照護機器人。因此，本研究將御宅族當成目標使用者，並製作了一台動漫風格的類人型陪伴機器人，命名為「惑星靈」。本研究假設御宅族容易與虛擬角色建立情感連結、接受新科技的特質可以增加人型陪伴機器人的正向體驗，並且可能是最先購買人型陪伴機器人的一個年輕族群。惑星靈是一台高約160公分，底盤為輪型的動漫風格陪伴機器人，具有注視、牽手跟隨、眨眼、觸覺互動的功能。
本研究主要於成功大學同人場進行互動及問卷調查，成功大學同人場為台南最大的動漫活動。共回收93份有效問卷，分析結果表明與虛擬角色建立情感連結的特質與使用者的正向體驗呈正相關，科技接受程度因為取樣問題而無法判斷。教育程度、性別、性傾向、孤獨感皆與使用者的正向體驗無顯著相關。結果也證實生命感與陪伴感有正相關的影響。使用者大多對惑星靈評價良好。

Humanoid companion robots specifically designed for young users remain rare. most existing models take the form of pet robots or are intended for elderly or disabled care. This study targets the otaku demographic and introduces "Hoshi Zero," an anime-style humanoid companion robot. The research hypothesizes that otaku users, due to their propensity to form emotional attachments with virtual characters and their receptiveness to new technologies, may have more positive experiences with humanoid companion robots and represent a likely early adopter group.
Hoshi Zero stands approximately 160 cm tall, wheeled base plate, and supports functions such as gaze, handholding and following, blinking, and tactile interaction. The study was conducted primarily at the NCKU doujinshi convention, the largest anime-related event in Tainan, where 93 valid questionnaires were collected.
Results indicate a positive correlation between the tendency to form emotional connections with virtual characters and positive user experiences with the robot. No significant relationship was found between user experience and education level, gender, sexual orientation, or loneliness. technology acceptance could not be assessed due to sampling limitations. The findings also demonstrate that perceptions of animacy positively influence feelings of companionship.
