The "RC servo" page should be merged with "Servomechanism". RC servos are a specific subset of servomechanisms. As long as its done properly and all of the content is retained, i see no reason why the pages can't be merged.

[edit] vandalism
I wasn't login at the time so it appears has my IP. I have reverted both changes by 193.132.24.231 has they were vandalism the page by changing words

[edit] merging servo and RC servo
yes join them —The preceding unsigned comment was added by 86.142.85.145 (talk) 09:50, 5 May 2007 (UTC).
No don't join them. I'm not an expert, but RC which stands for radio control(led) is a special subset of servos. It seems to me that the author of the RC servo article isn't an expert either and is actually describing wired servos - although I could be mistaken. Ideally, rather than see the articles merged, I'd like to see both articles expanded with a small section on RC servos in the main servo article - linking to the lengthier RC article. I'm not expert enough to make these changes.
Also I think that they should remain separate because wired servos of many different types are used for many different functions in many different industries. The RC aspect of RC servos should be expanded upon in its own article.
Time to merge! I think we can have a section in servomechanisms about the RC portion. --72.241.176.124 23:47, 28 May 2007 (UTC)
[edit] Proposed change to intro
This intro is too narrow. Servos are more broadly used. I propose something like the following:
A servomechanism, usually shortened to servo, is a device used to provide control of a desired operation through the use of feedback. Feedback is the term used to describe the use of a sample of the current output from the system which is "fed back" to an earlier part of the system (earlier in the forward signal flow) to bring the system's output closer to the desired result. An example of a servomechanism is a home furnace controlled by a thermostat.
INFO: The R/C servo is indeed, only one type of (position control) servo. Others are Furnace (temperature servo) Automotive power steering (force servo), Phase-Lock Loop (phase servo), AM radio AGC ( amplitude servo), FM radio AFC (frequency servo).
INTERESTING: The term servomechanism was originated in H.L. Hazen's 1934 paper Theory of Servomechanisms, Journal of the Frankiln Institute, from the words servant (or slave) and mechanism. This from Feedback Control System Analysis and Synthesis", D'Azzo & Houpis, 1966 McGraw-Hill.
I'll make these citations legal if they are used.

The section on control inputs for an RC servo, while interesting, seem to be describing a certain model, which isn't identified. If it's really a general standard, someone should say so, but otherwise, the info should be removed or, if it's a very common model, qualified. 207.179.248.39 23:43, 12 August 2007 (UTC)
- That PWM format (1 to 2 ms pulse width, about 60Hz rep rate) is a de-facto standard in hobbyist R/C servos. It's not single-vendor. But it's not formally standardized, as far as I know. --John Nagle (talk) 04:31, 23 December 2007 (UTC)
- I'll back up the above user, having tested a range of servo-transmitter pairs, I found 1.5 mS, 55Hz to be the norm across the range Jdedmond (talk) 15:17, 23 March 2008 (UTC)
[edit] Proposed merging Servo drive into here.
I've proposed merging Servo drive into there. That article isn't very good, duplicates content here, and may just be a placeholder for an advertising link. --John Nagle (talk) 04:33, 23 December 2007 (UTC)
Good idea
[edit] PWM Operation
Would other users find it helpful to have a (oscilloscope-like) trace of the PWM'd waveform used to control the servo? The control of servos via PWM (pulse-width-modulation) is mentioned, and discussed briefly, but no diagrams are present. I certainly feel that it would help to improve the readability and ease of understanding. Jdedmond (talk) 15:05, 23 March 2008 (UTC)
[edit] Rewrite
I dont know anything about servo motors I cam here to learn the difference between brush and brushless, ac and dc. and theres barely mention of any of it in this article. It should be deleted and completely rewritten. —Preceding unsigned comment added by 72.40.28.250 (talk) 17:39, 8 June 2008 (UTC)
