Here is a servo that is less than $10 http://www.servocity.com/html/hs-311_standard.html
people usually use standard size servos unless you making a flying robot or something really tiny.
lightweight rechargeable battery pack(9V)
900 mA is fine
umm i dint get it... or is mAh something different than mA?? anyway... I'll be using this 9V for my arduiono robot and i hope it wont burn my servos and IR sharp range sensor...or will it?oh and if there is a difference between mAh and mA then please tell what is it thank you
umm okei then...I'll use 7.2V batteries then... but how many mA should the battery have? ( any calculation didn't tell me that )

( any calculation didn't tell me that )If you use 7.2V you are shortening the lifetime of the servouse Admins battery calculator http://www.societyofrobots.com/battery_calculator.shtml to find out what battery you need
If you use 7.2V you are shortening the lifetime of the servo
where does he say that?im saying it would work, but would shorten the lifemaybe 7.2V for the regulator
admin i don't think i will ever let my robot run for an hour Cheesy maybe 10 minutes max Cheesy i mean continuesly Cheesyor do u turn on ur robot for a whole hour sometimes?
do i have to use another battery for my IR range finder? and does anybody know how many volts does a IR need anyways?
omg i just found 6 NiMh rechargeable batteries 600mAh each and i have a recharger too so i can just put them together and i have my 7.2V and 3600 mAh isn't that perfect? oh but could anybody give me an advice how to connect all these batteries together?

Quotedo i have to use another battery for my IR range finder? and does anybody know how many volts does a IR need anyways?power it from the 5V regulatorQuoteomg i just found 6 NiMh rechargeable batteries 600mAh each and i have a recharger too so i can just put them together and i have my 7.2V and 3600 mAh isn't that perfect? oh but could anybody give me an advice how to connect all these batteries together?power bus
You should put some more thought into your questions, many of the answers would be obvious when you sit down and try to figure it out, google search, etc.Search google for answers, and draw up a schematic for us to look at.We will let you know if it is correct . . . I'm confident you can figure it out on your first try, you just need to put in the work . . .
