Confusion about Servo!

[reefat]

I am little confused about the difference between Digital and Analog servos. I read the article about the difference on http://www.societyofrobots.com/actuators_servos.shtml. But I couldn't find anything to distinguish a digital servo from an analog one.

Recently I bought 2 servos from Ebay. Please take a look at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=310077396962. Is there anyone can tell me whether it is a Digital Servo or not?

HS-311 is a standard size analog servo

Digital servos are better and more precise but will wind up costing way more than analog

I was just thinking this same question. How do you interface with a digital servo versus an analog servo?

[airman00]

same interface and same connector

Here is an example of a standard analog servo  - http://servocity.com/html/hs-475hb_super_pro_bb.html
and heres a digital standard servo-   http://servocity.com/html/hs-5475hb_standard_digital.html

Digital servos refresh at 10 times the rate of analog ones and plus I think with certain hardware you can slow down digital ones.

Truthfully I really doubt you will need digital servos for hobby robotics.

@reefat : tthe answer to your PM - I would use 6V NiMh Battery Pack

@airman00: Thanks. That helps me a lot to understand.
