                              When  it  is  necessary  to  move  this  robot  arm  to  a  certain  position
                            within its work envelope, or the region in space that the arm can reach,
                            the operator enters data into a computer. This data includes the measures
                            of angles X, Y, and Z. In the example shown by the illustration, the oper-
                            ator has specified X = 39°, Y = 75°, and Z = 51°. For simplicity, no other
                            possible variable parameters, such as base rotation, wrist rotation, or
                            extension/retraction of linear sections, are shown.

                         DELIBERATION
                            Deliberation refers to any characteristic of robotic navigation that involves
                            advance planning of some sort, rather than mere reaction to the presence
