6 AX-12A Dynamixel actuators
1 ArbotiX-M Robocontroler
You also need six Dynamixel 3 pin cables.

I purchased these from Trossen robotics, the assembly guide for their robot arm Phantom X Pincher
is a good resource as my arm is similar in design.
You will need a thrust bearing 35mm x 52mm x 4mm Needle Roller Bearing Thrust Ball Bearing AXK3552
You can buy these off e-bay pretty cheaply.
You will also need to get your hands on some RC car wheel bearings the arm uses three, 1 in the elbow 1 in the wrist and 1 in the shoulder joint.
measurements of these are 5x11x4mm you should also be able to purchase these pretty easily on e-Bay.
Nuts and bolts,
I've added some extras because it is very easy to lose these tiny screws.
40 M2 x 8
12 M2 x 10
4 M3 x 10
