Abstract
Robots that write characters like human have attracted our attentions. We construct a system that rewrites handwriting characters by employing a ready-made robot. The data of handwritten characters are recorded by using a pen-type haptic interface. Since it takes long time to track a lot of recorded data by the robot arm, the number of data is reduced. However, the features of characters are eliminated if the reference data are reduced more than needs. Therefore, an appropriate rate of reducing data is investigated in questionnaires and experiments.
