    I don't know about 21 oz-in, but Innovati seems to get away with micro servos:

    [ame="http://www.youtube.com/watch?v=9MC3IkTxBTU"]YouTube - mini hexapod[/ame]

    When you consider batteries and such with it, I'd go for broke and would use something like these:

    http://www3.towerhobbies.com/cgi-bin...?&I=LXLN96&P=0

    I believe those two are identical servos. Tower Hobbies servos and equipments are often re-badged Hobbico, and Hobbico items are often re-badge of Hitec Servos...

    Both of them have 54-55 oz-in of torque at 4.8V! For micros, I'd look at 4.8V ratings since you want to keep your payload (batteries) to a minimum...

    I'm waiting on Lynxmotion to make some micro brackets. It's one of the things on Jim's to-do-list for 2008, I think you'll probably start to see some micro-servo based bots once he releases his brackets...

No problem with cutting the bits myself... Is a 21oz-in servo enough to carry a small battery and an SSC32, as well as its own servo weight?
    You might have to go with the beefiest micro servos you can find - maybe something like the S3155 digtal. A micro sized hexapod or octapod would be cool. They remind me of those hexapods in Runaway. I so want to build a multipod one day, but the cost of servos keeps me from starting a project like that.

    What is the angle Φ?

    My GIMP angle tool measure 60 degrees, is this correct?

    Hi Tom,

    Well I did setup my Phoenix a bit different, see this picture (hope its ok to use your):


    I choosed the angle that gave the leg most freedom without crashing into the body.

    No gurantees that my pixel pitch is the same as yours, but I printed it out and put the digital protractor on it and got 63.74deg

    Sienna, if your other pictures contained the angle he's looking for: They're broken for me.

    There was a brief period where I realized I had uploaded the non-cropped versions. That was only like a couple of minutes though, so I don't see how you got those! If you refresh, you should see them. They are working for me.

    A control-refresh still shows the bottom two broken, but clicking on 'em works now. Go figger!

    Oh - I get it. There are two identical (but broken) thumbnails underneath.
