- Abstract
Objective To explore the operational principle of Cartesian-coordinate writing robot about its imitative signature handwriting and related characteristics on which how to consequently influence with the robot’s parameter setting. Methods The personal man-made signature handwritings and those of the writing robot were collected, having been observed into the characteristics of the robot’s imitative signature handwritings with the help of instruments (i.e., VSC8000 and RTI here). Results As the robot’s imitating signature handwriting is designed on Bezier curve and consecutively converted into G instructional code to control the robot to carry out writing, a highly consistency exists between the robot’s imitating signature handwriting and the one of personal man-made about their general features, local arrangements and writing-regulated features, yet the differences being present among their allocable proportion, repeated strokes, stroke order, pen’s running route and marks. Strokes’ jitter will result from the larger parameter setting of acceleration and speed. With the pen pressure-parameter augmenting, the pen marks maintain from gradual deepening to remaining unchanged. The pen’s closing stroke is to elongate along with the pen pressure/stroke parameters augmenting. Conclusions There are essential differences present in writing principle and handwriting characteristics between the robot imitative signature handwriting and the one of personal man-made, laying a feasibility for identification about such kind of signature handwriting.
