Cartesian or Rectangular Configuration
	The Cartesian Configuration provides for three linear axis of movement at
right angles to each other. The modes of movement are similar to those on a milling
machine, providing movement in the X, Y and Z axis. It can also be called
Rectangular Confguration as its working range sweeps a rectangular volume.
Advantages
   - Easily programmed and controlled movements
   
 - Good accuracy
   
 - Simple control system
   
 - Fast operation
   
 - Inherent stiff structure
   
 - Large payload capacity
   
 - Structural simplicity, giving good reliability
 
Applications
	Applications include areas where linear movements of high accuracy are
demanded eg manipulation of components through apertures ie fumace doors and
machine openings.
