Summary

This is a 6 degree of freedom robot arm designed for AX-12A Dynamixel robot actuators. It's similar to the turtle bot arm.

Instructions

Things you will need.

6 AX-12A Dynamixel actuators

1 ArbotiX-M Robocontroler

You also need six Dynamixel 3 pin cables.

1 100mm cable

5 200mm cables

I purchased these from Trossen robotics, the assembly guide for their robot arm Phantom X Pincher
http://www.trossenrobotics.com/productdocs/assemblyguides/phantomx-basic-robot-arm.html
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

40 M2 nuts

Of the 3-D printed parts

You will need to print one of each of the following

base_legs_arbotix_m.stl
base_turn_table_bot.stl
base_turn_table.stl
base_turn_table_spacer.stl
wrist.stl
wrist_rotate.stl
the_crawer_base.stl

You will need to print 2 of each of the following

the_crawer_lever.stl
the_crawer.stl
f4_n_f3.stl

You will need to print 3

servo_hinge_flange.stl

Most hobbyist 3-D printers should be up to the task.

You will probably need a file or something to make sure all the parts fit as intended.
