koran49 said:Yes I guess it does, so what your saying is set the slider to 255 and the servo should stay on continuously? Do you know how I would make the servo stop when I got it set where I want? Like say move it to 254 maybe? Also not sure if you would know the answer to this but does the setting 150 center/home the servos basically? I guess I should just order the stuff and see what I can do lol.
koran49 said:Umm as far as languages I only know a little of VB, thats one of the reasons I want to do this is so that I can learn some programming. My friend and I are doing this as a school project so we are going do our best to program this together.
Please don't tell me your entire post was about semantics.Nigel Goodwin said:I'm rather confused about what you are wanting to do?. A servo CAN'T rotate continuously, if it does it's no longer a servo - the output shaft is connected to a potentiometer, which has a MAXIMUM POSSIBLE 270 degree rotation (it's unlikely a servo would achieve that much though?).
It's common practice to modify a servo to give continuous rotation, particularly for small robots - however, it's then not a servo - just a motor and gearbox.

Roboticinfo said:Nigel that sounds rather strange that you would say something like that.
They sell servos with full rotation and they are easy to modify a servo todo so. In robotics a populer item to use in robotics is servos, Usually thet have two servos and they connect the wheels to the servo horn, They use them in small robots
www.robotcafe.com and elec.
You must not be into robotics if you ask a question like that
Here are websites that sell wheels for servos
Roboticinfo said:Then we should be directing him towards pwm speed controllers
if that is what he wants.
I don't think he does? - as I understand him, what he wants is to be able to make a linear actuator using a screw thread. Obviously to do this you need feedback so you know where it's positioned - JUST like a servo, and it is actually building a servo if you do it in that way.
Assuming you can get a slider potentiometer driven by the actuator? (which obviously depends on the length of travel!), an easy solution would be to modify a servo, and connect the external slider in place of the internal one.
koran49 said:forgot to mention the approximate length for the actuator I need is going to be about 24"
koran49 said:maybe I'm just not understanding you right but when you said how am I going to achieve 24" with 180 degrees were you refering to the servo motor?
