DARwIn-OP is an acronym for (Dynamic Anthropomorphic Robot with Intelligence - Open Platform) or DARwIn for short. The DARwIn-OP was developed by the RoMeLa research lab at Virginia Tech in collaboration with University of Pennsylvania, Purdue University and ROBOTIS. ROBOTIS is a world leading South Korean robotics’ company. Their Dynamixel servos are the leading robotic servos in the world and the key to why the DARwIn-OP is so ground breaking. The lead designer of the DARwIn-OP project has Dr. Dennis Hong of Virginia Tech’s RoMeLa and ROBOTIS. The robot is a state of the art research and development humanoid robot. The DARwIn-OP weighs in at about 2.9 kilograms and a height of 45.5 cm.
The idea behind this project is to find new and cheaper ways to create and build robots. As 3d printing becomes cheaper and easier to use more and more people will have access to this way of manufacturing. I hope that this instrucable will open up more peoples eyes as to the power of this new personal fabrication method.
Below is a link to my Make magazine article on how I made the clone.
Step 1: Why I Wanted to Own a DARwIn-OP!

Step 2: Download CAD File

Step 3: Create .STL Files for All of the Parts.
If you need a cheaper way try AutoDesk 123D Beta if you can still download it.
Here is a link to my Thingiverse project page for my DARwIn-OP clone where I have upload all of the .STL files for the robot.
Step 4: Print Out All Parts on a 3d Printer.
Step 5: Buy the Electronics for the Robot.
The easiest part of this project.
Step 6: Buy Your Servos for the Robot.

Step 7: Buy Fastners for the Robot.
Step 8: Assembly Robot
Step 9: Download Software to Robot and Laptop

Step 10: Turning on Robot for the First Time
Step 11: Test the Robot
Step 12: Redesign Parts That Break
Step 13: Print Out New and Improved Parts
Step 14: Reassembly Robot With the New Parts.
Step 15: Retest Robot With New Parts.

If you are like me, you will we always be going back to step 14 because of new ideas or ways to make your robot better.
Total cost for my project was 6000 USD if you don't include the 3d printers that I used. A lot of money yes but if you buy a factory made DARwIn-OP from Robotis the cost is 12,000.00 USD. So I saved about 50% of the cost of the robot by building it myself.

Step 18: Future Upgrade Possibilities.
Simplest would be changing there color to hardest which would be modifying their design.
A great example is changing the color of the covers to mimic the Ironman power suit.
Jet-pack and weapons for the power suit may take some more time and research.
