摘　　要：写字机器人是伴随着电子雕刻技术、3D打印技术以及计算机仿真技术的发展而出现的一种书写设备。根据其构造的不同,可分为直线关节型、曲关节型和平面关节型三类。近年来,随着写字机器人的大众化,其潜在的风险隐患引起了国内外文件检验界的关注,为此,业内从笔迹学的视角对其进行了大量的研究。本文基于这些成果,首先综述了写字机器人的种类以及工作原理,然后总结了直线关节型写字机器人和曲关节型写字机器人写出的字迹的特点,在此基础上介绍了机器人字迹鉴别的方法以及业内对机器人摹仿能力的评价。最后指出了现有研究存在的一些问题,并针对这些问题展望了今后这一领域的研究趋向,强调要密切关注这种设备的发展态势,将潜在的风险问题防患于未然。Writing robot is a kind of writing equipment;it came into being with the development of electronic engraving technology,3D printing technology and computer simulation technology.According to their different structures,they can be divided into three types:straight joint writing robot,bending joint writing robot,planar joint writing robot.In recent years,due to the low price and good writing effect of the writing robot,this device has become popular,and may be used by some people to forge handwriting.Its potential risks have not only attracted the attention of domestic handwriting examiners,but also attracted the attention of some foreign handwriting examiners.For this problem,they conducted a lot of experimental research and theoretical discussion from the perspective of graphology.Based on the published papers at home and abroad,this paper first summarizes the types of writing robots and their respective working principles,and then summarizes the characteristics of the handwriting written by straight joint writing robots and bending joint writing robot.On this basis,four methods for recognizing robot handwriting are introduced,they are:overall feature recognition,detailed feature observation,analysis of handwriting overlap comparison,and computer automatic recognition.At the same time,this paper summarizes the social evaluation of robot’s ability to imitate human’s handwriting.Finally,it points out some problems existing in the existing research,which are mainly manifested in two aspects:first,there is a lack of in-depth analysis and research on the influencing factors of handwriting characteristics of writing robots,especially the lack of correlation analysis on how various writing parameters affect handwriting characteristics;second,there is a lack of necessary tracking research on some new writing robots.In view of these problems,the future research trend in thisfield is prospected,and the development trend of this equipment should be closely watched to prevent potential risks.
