 Practical tips
 ==============
 
-For controllers, the frictionless pins are next to useless
-except in very special circumstances.
+The two most difficult goals to achieve are
+avoiding mechanical looseness and
+obtaining a rugged structure.
+While interrelated, the second problem is more relevant
+to robotics and has therefore been dealt with in that context 
+due to the popularity of the LEGO Mindstorms.
+
+Mechanical looseness is a different matter; it suggests
+the following design rules:
+
+- No frictionless pins.  For controllers, the frictionless pins are next to 
useless
+  except in special circumstances due to their looseness.
