- Abstract:
-
A novel robot calligraphy system is proposed to enable robots to write Chinese characters by using a brush in a slanted position, with the purpose of solving the problem of the existing robot calligraphy system taking only the straight state of the brush into consideration. First, writing marks are analyzed in this proposed system, and an appropriate stroke model is established based on the linear regression algorithm. Then, the trajectory information is obtained from the stroke image by using genetic algorithms, which are added with the rules of starting, running, and closing for virtual stroke images. Lastly, path planning for robots is realized by using a B-spline algorithm, and posture calculation is fulfilled through coordinate transformation, thereby achieving actual writing. In the experiments, three stroke characteristics are extracted as evaluation indicators. Experimental results show that the robot brush calligraphy system can achieve a better writing effect.
