In this study, a robotic intelligence writing system is built based on the Uarm to learn Chinese character strokes. This system can finish automaticly strokes spliting and writing of unfamiliar charater. Besides, based on the dialogue technology and image processing technology, the system can learn the correct strokes from human. Firstly, the system gets the keyword which user want to write and user intention according to the input voice information and the word image information from camera. Then it analyzes the word image and splitting and extracting the strokes if the keyword is detected. If the word is being taught by human, the system would record the strokes order and learn the correct way to write the character. Through the dialogue management, the Uarm can interact with human through wrting and dialogue, learn form human, and write the characters correctly. According to the experimental analysis and subjective evaluation of the test, the system has been well recognized.
