A kind of host is to be equipped with the processing unit being electrical connected, a Transmit-Receive Unit, an image acquisition unit, an interactive unit and a feeding unit in a hollow interior of shell. Transmit-Receive Unit transmits a signal to processing unit and carries out logic calculus, and sharp what, which is raised, main to be generated in remote control interactive unit just like feed needed for the telepresenc that nearly body companion pet is played, and/or starting feeding unit supply pet.一種主機，是在一中空的外殼內部，安裝有電性相連的一處理單元、一收發單元、一影像擷取單元、一互動單元與一餵食單元。收發單元傳輸一訊號至處理單元進行邏輯演算，利於飼主在遠端控制互動單元產生宛如近身陪伴寵物玩耍的臨場感，及/或啟動餵食單元供應寵物所需的飼料。
