GRAPHICS TABLET EMBED JAVA-APPLET AND WEB-BASED TELE-CALLIGRAPHY OF PNEUMATIC MANIPULATOR

摘要

Java becomes one of the most acceptable programming languages in the Internet because of the characteristics of distribution, object-orientation, interpretation, and independence of computer platform. An application code programmed in Java can be downloaded and run in any client machine with Java VM through Internet. Most of internet-based application uses Java as the first choice of programming language. The Web-based Tele-calligraphy of pneumatic calligraphic manipulator described in here is one of these applications. In this article, authors will discuss the procedures of how to embed Unispen software package Wintab to Java-applet using Java native interface (JNI). In the server machine, all communication functions between pneumatic servo-controller SPC-200 and computer had been compiled and linked to a dynamic loaded library in Ch language. Under the C/C++ superset interpreted language Ch, calligraphy handwrote by user in client machine will be formatted, sent, and calligraphed in a far located pneumatic robot manipulator through Internet.
