The DARwIn-OP is a open hardware and software project which greatly aided me in doing this project.

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!

I thought it would be a good idea to show a production version of the DARwIn-OP in action to show the reason why I wanted this cool robot.

This is video of the DARwIn-OP in its natural environment Robocup soccer.





Step 2: Download CAD file

First step was to download all of the 3d CAD files.

Link to file location.

Step 3: Create .STL files for all of the parts.

I used Autodesk Inventor to create my .STL files, you can use your favorite 3d design software.

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.

I used the UP! Plus 3d printer to print out almost all of the robot, again you can use a 3d printer that you own or have access to. This took me almost two months to get all of the parts printed out correctly.

UP! Plus 3d printer.

The Afinia H-Series: 3D Printer is the exact same printer.

Step 5: Buy the electronics for the robot.

The easiest part of this project.

Step 6: Buy your servos for the robot.

Yes the MX-28T servos are expensive but they are state of the art robotic servos. The servos of your robot are alwas the key as to how well your robot will preform.

Link to where to buy them.

Step 7: Buy fastners for the robot.

Robot Cloning by DIY 3d printers!
It may not seem like it but this was one of the hardest parts of this projected. I was aided by the detail list in the assembly manual. After a lot of phone calls and e-mails and internet research I found McMaster-Carr in Chicago was the best place to order fasteners from.

Step 10: Turning on robot for the first time

Robot Cloning by DIY 3d printers!
This is always a very scary moment when doing this for the first time.

Step 11: Test the robot

This is also a terrifying moment but it can also bring great joy!

This brings out the great advantage of personal fabrication. The ability to make part after part until you get it right or iteration.

Step 17: Robot is working!

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.

Modifying the covers of the DARwIn can lead to some interesting modification ideas.

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.

The images where created in AutoDesk Inventor by my friend Yoshihiro Shibata.
