These are parts to the DARwIn-OP. Which is a open hardware and software research robot.

McMaster Carr is great but I had to buy 50 to 100 of every screw. Which got expensive. Robotis needs to come out with a screw kit.
I uploaded a test video of my darwin OP right leg. youtube.com/watch?v=Bld407HPdMQ

Instructions

I should add that we are creating our STL files in AutoDesk 123D. I am starting to like this software more and more!

Here is a link to my instructables guide on how I made the DARwIn-OP clone for more information.

I uploaded a test video of my darwin OP right leg. youtube.com/watch?v=Bld407HPdMQ
where can i buy the screws?
mcmaster carr or grainger has them usually

are these parts scaled properly? i imported the head file and it says its only 10mm wide?
At one time they were but not know? I uploaded the same files that I used to print my DARwin-OP. I will fix and reload them.
Can you let me know from each items, how may time printing is required, please?
At least two of each.

Go to my instructable and downloaded all the assembly manuals for a detail parts list.

What parts are needed?
What size and strength of servos?
How many?
 The robot is design to use 20 DYNAMIXEL MX-28T. They are about 220.00 USD a piece. Yes I know they are expensive but they are awesome servos.

Assembly manual is here
I see the STLs but where are the Autocad 123D files?
 http://www.robotsource.org/xe/index.php?mid=Circle_Darwin&page=7&document_srl=7051

CAD file are here
 I will try to upload the 123D files
The UP! can now print with a .15 mm layer height! The covers of the OP are looking awesome now. Did not think that I could print them out! It just takes a long time for each print!

Will have a very cool update to this project in a few weeks!!!
I love the project but those servos are REALLY expensive
219.00 USD for a state of the art servo is not bad =-X
i just finished my phd in neural computation specializing in developmental knowledge representation and sensorimotor grounded language acquisition, and continually through my phd i kept thinking of how my project would benefit from having access to "real" sensiromotor data from a small humanoid robot instead of the simulated data i was using (and, of course, you have to start this way -- but it's nice to make the transition at some point). i was trying to price one of these out the other day, and really the $10k price tag seems like it's ALL servo. what makes them $220 each? is it the torque, or the digital interface with feedback? could you take a much less expensive but similarly torque-speced servo, and add on some small boards of your own design to give them the same functionality for a quarter of the price?
Peter have you priced robotic servos lately? Here is a write up on what makes the MX-28s so cool! hizook.com/blog/2011/06/16/new-robotis-dynamixel-servos-mx-28-sport-360-degree-rotation-and-4x-angular-resoluti

As for a cheaper version. Me and a lot of other people are working on that!! =-X

They are talking about making a DARwIn-OP with AX-12A servos! =-X
