Re: Mulit-postioning with pnuematics this year?
Some follow-up /
First, this does work and we have tried it out on our 2003 robot. very controllable. One thing, you have to cycle full up and down a few times to charge up the whole system with compressed air. Then it is stable.
While experimenting, dial in the fittings to be very restrictive - it wil slow everything down and it is easier to see the efects of what you are doing.
Also, I added a pressure gage in the line. It never went above 60 psi. I don't think that is right, so I am going to change around the gages and see if it is just gage error. The math says it should be > 60, but maybe tiny leaks and volume keep it from reaching that high.
We used 2 switches. On double action to the the dual solenoid. selecting left or right will define the direction the cylinder travels. The second switch is a momentary on that is connected to the single solenoid. Pulses on this switch vent the cylinder and it moves in the direction set by switch 1.
Our programmers are trying to set up the control to do this. We are going to try some limit switches or something and see if we can stop it automatically with the control.
I have a power point slide that we used tonight in our design review. If someone can tell me how to add it to a post I will insert it. It makes it pretty clear and easy to convince the non-believers.
Like I said in an earlier post - this is awesome and thanks for sharing the idea.
