From the servos info page: https://robotics.stackexchange.com/tags/servos/info
Most servos questions should fall into the subcategories of either industrial servomotor or rcservo (with the synonym hobbyservo). Only questions which do not fall into these two sub-categories should use this tag.
To summarise this taxonomy of tags:
- 57 servos questions, last in January 2017
- 42 rcservo questions, last in October 2016
- 59 servomotor questions, 5 asked so far this month
Part of the point of the servos tag is to help identify questions which haven't been correctly tagged as either either rcservo or servomotor.
The idea was that if you see a question tagged with servos, anyone could suggest an edit to the question to re-tag it with rcservo or servomotor as required. If it wasn't clear from the question whether it was referring to an rcservo or a servomotor, then this could be clarified and then properly tagged.
There was a time when I would go through servos tagged questions myself doing this, but then the community started doing it, and I just had to approve the suggested edits.
Although it looks like a clean up may be required, I think the basic principle still stands and our current taxonomy is the correct solution top the problem of servos questions being consistently being mis-tagged.
2020 Update
After making hobbyservo and digitalservo into synonyms of rcservo and making servos into a synonym of otherservo the problem seems to have reduced substantially:
There are still questions in otherservos which would be better off tagged with either rcservo, servomotor or both, and there are still questions tagged as one which should be more accurately tagged as the other, so feel free to edit these tags (or suggest an edit) when you find them.
