It's pretty much a bioloid, but with 4 extra servos (two more dynamixels and micro servos to rotate each wrist) until the head comes, then it will be a bioloid with 6 extra servos. (the JD head)

I don't have a camera yet, but when (if) this robot is finished, i'll find some way to take a picture.'

EDIT: He also has a changed leg frame. Instead of having the bend part for the knee joint, he has another long straight piece.

EDIT EDIT: So at the middle joint of the knee, this frame piece: http://www.trossenrobotics.com/store/p/6179-Bioloid-Frame-F1.aspx is replaced with this: http://www.trossenrobotics.com/store/p/6182-Bioloid-Frame-F4.aspx

CupcakehatBasically you could use the white lead as the signal control wire from the EZ-B and cut the red and black leads and run battery power to each servo from your 12 volt power source.

then could I just power the 6v / 7.4v servos straight from the board using a 6v power supply to the board?

If you use a 6 volt source to power the EZ-B then it could also power the 6 volt servos but the 7.4 volt servos won't be getting the optimum power for operation. Also you need to consider what the total servo amperage will be. I believe that the EZ-B has a 4 amp limit.

A quick search found they have 35mA stall current (however I do not know how reliable the information is) therefore you have 4 which may pull 35mA each...

4 x 35mA = 140mA

Check the stall current though, I struggled to find it and only found it in one place which required a calculation (subtracting the controller's current draw from the total draw to leave only the servo's current draw) so it's possibly not too accurate.
