Hey All.
I'm doing a little project at home where I have a need to automate something.
I have never played much with servo or stepper technology but this I think is well suited.
Its a small application where I need to move a lever a total throw of about 5 inches. No problem, but I need to stop in 6 pre-defined positions along the way.(One being home, full retraction) The lever is very easy to move and can be done with lightly applied finger type force. Speed is the name of the game. I need it to move between the positions quickly.
Iv been looking at a lot of the stuff available for this kind of thing and its endless. I am however having trouble finding a tiny linear servo, with position feedback that has any speed to it. One unit was .51"/sec. A little to slow.
As for driving it, I'm thinking of a small controller that may be part of a system to work with above mentioned linear actuator, or perhaps an Arduino solution, simply to see if my project is going to work anyway..
I have included a simple concept drawing to illustrate what I want to do. My drawing only shows 5 positions but I have a need for 6.
So, question is.. Can anybody recommend me some equipment that may help me. Has anybody done something like this before with fine positioning? Perhaps there are better methods than using a linear actuator????
Any thoughts??
