Thanks for the clarification. Issue solved.

For others if in similar situation please pay attention to this Simply remove the z constraint (you have defined your IK element relative to the base object of your manipulator, and so your constraints are relative to that object's reference frame ...

A very detailed and clarifying answer. Thanks a lot!

I stumbled upon the following: in an single 3 links+2 revolute joint model the mass of the links determines successful inverse kinematics.
Image of the the model: https://www.dropbox.com/s/q1q2vflci55bazj/Capture.PNG

If the model is assigned a mass of 1.0 (kg?) for each link, the model would ...

The following basic set up: three boxes and two revolute joins breaks under the inverse kinematics pseudo inverse calculation method. Even if the target object is restricted to within reachable areas and the XZ plane (where the robot lives). What causes this behavior? Is this a restriction of ...

On the inverse kinematics tutorial http://www.coppeliarobotics.com/helpFil ... torial.htm, the name "redundantRobot" does not match the images. For a novice, this is confusing.
Thanks
