I have a few questions on what cam programs are avail ... that support the cordinates required to drive a arm? I dont think mach 3 supoorts them.
ie kinematics module ie translate cartesian coordinates/paths into
rotational joint position

has a simple 3DOF pneumatic arm.

I remember seeing plans a couple of places some time ago. One was basically a duplication of an old arm, using tapered sheet metal boxes for the portions of the arm, plus the end effector (hand). Reach was pretty minimal (12" on direction or so if I remember right).

Another used steel rods for the structure. With geared bolts with analog motors for actuators.

There was a third that was an 3 legged gimble system. like [ame="http://www.youtube.com/watch?v=LJYhz5aTMnA"]this[/ame] HexaPod on YouTube.

This web site has several different types of EMC2 controlled robot arms: HERE
