Pneumatic systems can be really fascinating to watch. They can also be
insanely frustrating when maladjusted. X-)
Cheap and crude cylinder technology may be, but they are probably the most
cost-effective way to do stuff in ever-cyclic assembly. Now that FESTO has
shown what you can do with proportional valve technology... it is a real
threat to conventional servo positioning techniques. It still just BOTHERS
me that airservos don't make ANY SORT OF NOISE. I almost REFUSE to spec
those in any of my designs simply because they just don't SOUND EXPENSIVE.
Servos HUMM. Servos SCREAM. Servos WHINE AND COMPLAIN when you push on them
and try to drop them out of servolock. Pneumatic cylinders....
Hiss. Click. Puff.
Now I'm geting all hot and bothered. Why do airservos have to look so
PROMISING?! They just look so PURE. There must be something wrong with them.
They don't have character. That's it.
