"servo" is generally taken to mean "servomotor" - which is the motor and position-sensing element.


Do you reckon ? A servo to me is the whole system

I do reckon - but only in the specific context that I mentioned.

What I actually said was:
When used in the context of robotics, radio control, etc, "servo" is generally taken to mean "servomotor"


In other words, if you went into a robotics or radio control shop, and asked for "a servo", you would get a little black box containing a motor and a pot...

My point was, as you say, that "servo" does indeed have a much wider meaning - but there are certain circles wherein it is (mis)interpreted much more narrowly.

It's a bit like some people talk about "CODE space" and "Flash" as equivalent for the 8051...


... and those people would be WRONG in any case wherein the MCU less than 64KB of FLASH. The 8051 (rip) has no FLASH at all. The 805x model has 64KB of code space, but, some have only 2KB of internal code space, some have no flash but have 4KB or 8KB of EPROM, while some have masked-ROM. Others have more than 64KB of FLASH. What do you call that? Isn't it incumbent on us, as engineers, to be not only communicative, but correct?

Its like calling that DE9 connector on the PC a DB9. Everybody can guess what you probably mean, but it's still the wrong nomenclature.
