Design And Development Of Control System For Writing Robot

With the rapid development of science and technology,the robot in the manufacturing technology and control level has also been greatly improved.More and more types of robots have begun to replace human beings in many fields to complete complex and dangerous works.In this respect,the performance of industrial robots is most prominent.Industrial robots are an important direction of high-tech research.With the development of depth and breadth of its application,it is urgent to solve the basic technology research of robot industry.Based on the study of the control theory and design method of industrial robots,this paper develops a set of robot writing control system based on X,Y,Z space Cartesian coordinate system,and analyzes the existing robot system in the process of writing The key issue.The main contents of this paper are as follows:First of all,to build this article hardware control system.On the basis of the mechanical mechanism of space right angle coordinate,the corresponding electrical schematic diagram and electrical control cabinet are designed with the industrial computer as the core structure,and equipped with the necessary external sensors and servo motor and servo drive to make the system smooth and reliable The operation.Then,writing the algorithm of font extraction to achieve the Windows TTF font information extraction.Using MATLAB ’s drawing function to simulate the extracted font information.Due to the limited information extracted from the font,combined with the Bezier curve theory,the use of spline interpolation principle,supplement font information.According to the supplemental font information,the space motion of the robot is tested differently,and the trajectory planning of the robot on the working plane is analyzed,and the movement effect of the robot under different modes is given.Finally,the preparation of robot motion control system software,combined with the font extraction process and motion control program,the operator can enter the appropriate text on the interface,select the font and size to be displayed,the robot can be specified in the work plane accurate drawing The text and text style,and in the end gives the corresponding experimental results.
