simulates a 6 link 3D Puma Robot (虚拟机器人)

代码说明：

This program simulates a 6 link 3D Puma Robot in the robots lab at Walla Walla College. The 3D robot looks "real" thanks to the cad2matdemo program.   The robot currently moves with kinematic control using direct input of joint angles and slider bars (GUI). Some inverse kinematics options are built in but not automated yet (a demo button). A random input is also provided and the robot animates between locations.   There are just two files to use. The main program and the six 3D-links data file that is read in at start up.   Try the "demo" button and the "Random Move" button.
