So, I spent the last couple days adding Voodoo control to BrainBot:

Most excellent Jon. What are you using for movement input sensors on the "voodoo doll"?

The AX-12 servos have that capability themselves. If you don't send the servo a position to try and reach, it remains compliant, and you can move it around and then ask for its current position.

One of the many benefits of using "smart" actuators like the AX-12...

I dont mean to steer off topic here, but on the AX-12 feedback...

Does the Bioloid software, or perhaps a 3rd party software, provide any sort of "motion capture" (think Kondo's Heart2Heart catch and play software) for creating sequences/motions using that positional feedback from the AX-12s?

Yes, the Motion Editor. You can see it in the point 6 of the Bioloid brochure (http://www.tribotix.info/Downloads/Robotis/Bioloid/Bioloid%20Brouchure.pdf) and the page 75 of the User's Guide (http://www.tribotix.info/Downloads/Robotis/Bioloid/Bioloid%20User%27s%20Guide.pdf)

interesting (yet creepy) work Jon!

Something like this can be taken a long way in robotics. Have you and Brain Engineering Lab discussed the possibility of adding in more teleoperated-like controls like users putting on "sleeves" wired with sensors detecting the user's arm movements?

EDIT: BTW, Tyberius, those AX-12 servos (http://www.trossenrobotics.com/bioloid-dynamixel-ax-12-robot-servo.aspx) (and the entire Bioloid system (http://www.trossenrobotics.com/bioloid-system.aspx) for that matter) are absolutely incredible! I'd highly recommend checking out all of the details on it if you haven't already:)

We have talked about that, but probably aren't going to do it. We just use the voodoo control to make demos (which we video), so it really doesn't buy us much to go to that level.

Regardless, the voodoo control that you already have setup is pretty dang cool!

How does this work though? I read your blog post, but it doesn't give me the juicy geeky details. Are you utilizing the feedback positioning of the AX-12's of the one robot, and relaying those positions to control the other?

Exactly, I asked the same thing earlier :p

Yes, I read the positions of each AX-12 in the "doll" robot, and send those positions to the corresponding servos in the "real" robot.

Doing stuff like this is actually pretty simple with the AX-12...
