Stupid questions:- Penumatic/hydraulic Servos
Hello again
I'm after some advice here, I need an extremely big steering servo for a project, It needs to have alot of touque and come back to center when i let go of the stick.
I've been looking at industrial servo motors, but the are very expensive and need alot of parts to work (Input>controller>amplifier>feedback>motor) and alot arn't suited for a mobile application (well that just what I found), I also tired one of those Oatley electornics monster servo kits and poped it with a wiper motor.
So I was wondering if its possibe to use air rams or hydraulic rams for servos? I found servo valves on ebay, will these make them work like servos? what are they controlled with?
Would it be possibe to use a standard servo to acctuate a manual valve, with a feedback device on the ram? I'd like to use a rotary table (penumatic, usualy made by festo,SMC or robomotion) maybe insted of a ram, the oatley electronics kit could be used to drive the standard RC servo directly on its motor terminals connected to the valve and the feedback pot on the rotary table. Do you think this could work?
I'm open to suggestions
Simon
