A kind of calligraphy robot

Robot used for calligraphy is a new area of research and application. It is also a challenge for servo system application and control strategy research. In this paper, a calligraphy robot is presented and the interpolation algorithm and coordinate transformation are used in the control system operation. The high-precision and intelligent control are implemented in the calligraphy robot to solve the key problems of the small radius rotation and the tracing control of calligraphy brush. The experiment results proved the accuracy and stability of the system and nice-looking writing.
