Here is an application that is very close to my need (I'm being a little
Imagine a x/y table, or arm, that can grip and pick up a pencil. that is, it
has two joysticks, one joystick functions in X/Y coordinates on the drawing
table, the other joystick operates the jaws and lifts the pencil up and down
on the paper.
What I want to do is to be able to have 4 preset buttons, each one will set
down the previous pencil, and pick up a new pencil. (you could name the
buttons "red pencil", "blue pencil", etc)
then go to the last position the arm was at on the drawing table.
Then, I could use the joystick to draw a picture. The complication is, the
joystick must control direction and speed, NOT ultimate position (Not like
an RC car, or the analog interface to the SSC that some kind soul
recommended a couple posts ago.)
That is, when I let go of the joystick, the movement stops, and stays where
it is. similar to a control on a backhoe.
Thanks very much for the input so far!

(funny, this is just a similar application to my main idea, but it might
provide some entertainment to a disabled person!e)
