I'm getting one for Christmas. The pneumatic parts in it are the new style, though. That means the big cylinders no longer have that "brick" at the bottom of them to attach to studs. All there is now is the Technice hole at the bottom. (22 years ago, 21-Aug-03, to lugnet.robotics)

Yes, you are on to something. Many industrial robots are "programmed" in much the same way.
