Can i use pins 16-19 for servos? Where are they linked to? How would i use them?
I know the normal pins are P0 - P15, but i need the extra 4 pins.
If so, where on the BB2 would i access them? or do i need to make separate headers?
With p14 (RX i think) being for my bluetooth adapter, i’m going to need all the other ports for servos. And even then, i’ll still come up short.
Cause i need at least 16 servos, 18 would be preferable.
I use a BB2 and BAPro 28-M
Yep, you can use the on a BAP28 for servos.

Do i have to solder header pins to the atom pro?
They aren’t connected to any BB2 headers?
Edit: never mind, i was bored so i grabbed my multimeter and realized they are connected to those first 4 header pins.
which work fine.
I should have enough slots now to make my 3dof quadruped, and keep my robot arm. I hope the servos i ordered are strong enough. 
are you building your quad with just the ABB? no SSC? sounds interesting.
what servos will you be using for this. i know that for a standard build you will get away with using hs485 servos for a 3dof.
but they will strain a bit. 645’s would be better. and i think anymore would be overkill, but very powerful. 
You’re forgetting who you’re talking to… I cant afford those.
no, i’ll be using 12 hobbypartz.com/60p-dy-1002.html
I don’t have sponsors or, anything like that to give me free stuff. And 12x $15+ servos… i cant do it.
Craft sticks, hot glue, and cheapo micro servos.
i’m going to try using the bb2, and the bap28.
And a small enclosure, otherwise, i’ll leave it open and just make a simple stick frame.
The legs, fully extended will only be about 5-6 inches.
I’m trying for small, and light weight… and most importantly cheap.
I’ll see if i can add the weight of my robots arm onto it after i’m done, i may need to make a new shorter arm though.
Sound cool. i like those servos. a miniature quad would be cool.
The other good thing is that with those servos wont pull much current so a nice small battery would work well.
what are your plans for chassis material?
here is a link to quad chassis designs: might help?

Gonna hotglue the base servos to a 2"x 2" hobby enclosure, if i use an atom nano.
Or a 3"x 2" if i go with the with the BB2.
I’ll need to double check some measurements first though.
Else i’ll make a very simple craft stick box frame.
The hardest part will be the programming, which you guys better prepare to help me with, but if all goes well, i’ll have a tiny craft stick and servo quadruped. I’ll marker/paint the sticks black though, make it look less… sticky.
Below is a simple hexapod made with small servos. It probably could be up scaled to use some of the larger inexpensive servos and still be in the hot glue craft/popcicle stick realm.
kind of already have an idea, the legs will be 3DOF, i already bought the servos, just waiting on the mail.
Need to buy a pack of hot glue too.
Already have a nice new bag of craft sticks too.
The general leg design will be the same as your more fancy ones. just minus the brackets and other fancier bits.
Besides the hot glue sticks, i have just about everything i need, well… besides the knowledge to program it, but i’ll figure that one out later.
Instead of a robotic arm, i decided i’ll just put a 2-3 dof head on it, and some mandibles/jaws.
As far as an enclosure goes, i could simply make one from popsicle sticks, light weight, flexible, but still strong.
First class mail, shipped out today, from california, should be here thursday at latest.
Any of you with quadrapeds on the basic atom pro, start uploading your BAS files, i’m going to need a whole bunch of examples to figure out how to make this.
