This paper introduces a calligraphic character writing system in which the generated characters are really written out on paper by a robot holding a writing brush. Being different from the conventional researches, the data base is made by means of a new method in which features of different style of calligraphic characters can be extracted with a uniform algorithm. Besides, we really constructed a robot for writing generated characters and the problems introduced by adopting a brush and their solutions are also discussed. In particular, because of the softness and friction against paper of the brush head, the postponement of the brush touch may be caused and we solved it by developing a special compensation method. In addition, an experimental result based on several style of characters is described. It turns out that, since the writing process is much similar to the one made by man, the aesthetic perception and momentum as well as some intrinsic properties of calligraphy can be better demonstrated.
