Abstract:	當科技日新月異，研究人員一直試圖更理解人類行為。其中一項重要的目的是讓機器人行為更加人性化，除此之外，人類還希望機器人可以擁有自己的情緒。為了達此目的，我們在本研究中設計了一個名字叫Shiau_Lu的仿真機器人，它擁有六個人類普遍的情緒，包括快樂，憤怒，恐懼，悲傷，厭惡和驚訝。當我們透過語音輸入一個句子給Shiau_Lu，它使用谷歌的語音識別方法辨識出該句子，並且將這個句子輸入到Android系統上運行，經過運算後，得到一個具有情緒的句子來表示目前的情緒狀態。這個系統的主要運算過程為，每個輸入句子影響六個用來各別表達情緒的六個變量之強度，而產生新的情緒狀態。其次，以模糊推理來推斷及確定最顯著情緒作為主要的情緒，並依之而從數據庫中選擇適當的句子作為輸出。當輸入另一個句子，則重複上述過程並輸出另一個語句及更新情緒狀態。在未來，可以讓自閉症兒童與該機器人對話，以增進其與人之間的互動關係，進而得以融入其周圍的世界。 Recently, researchers have tried to better understand human behaviors so as to let robots act in more human ways, which means a robot may have its own emotions defined by its designers. To achieve this goal, in this study, we designed and simulated a robot, named Shiau_Lu, which is empowered with six universal human emotions, including happiness, anger, fear, sadness, disgust and surprise. When we input a sentence to Shiau_Lu through voice, it recognizes the sentence by invoking the Google speech recognition method running on an Android system, and outputs a sentence to reveal its current emotional states. Each emotion is presented by a variable. Each input sentence affects the strength of the six emotional variables used to represent the six emotion variables. After that, the emotional variables will change into new states. The consequent fuzzy inference process infers and determines the most significant emotion as the primary emotion, with which an appropriate output sentence as a response of the input is chosen from its Output-sentence database. With the new states of the six emotional variables, when the robot encounters another sentence, the above process repeats and another output sentence is then selected and replied. Artificial intelligence and psychological theories of human behaviors have been applied to the robot to simulate how emotions are influenced by the outside world through languages. In fact, the robot may help autistic children to interact more with the world around them and relate themselves well to the outside world.?
