This is a Robot Micro Servo Arm that I want to use to learn about servo motors. Probably I'll be making the hole robot and this could be the left arm of that robot.
I used 3 TowerPro SG90 servo purchase on dx.com (the third I thing I'll be using a grip or something.
This are the specifications:
Operating speed (4.8V no load): 0.12sec/60 degrees
Stall torque (4.8V): 2kg/cm
Temperature range: -30 to +60'C
Dead band width: 4 usec
Operating voltage: 3.5-8.4 volts
Last picture is Version 0.1 I make a hole so I can pass the cable through and put the all together.
Suggestions and comments are highly appreciated.

I just uploaded a file that you can print out to have the Arduino Board next to one servo in order get stability. Also I put on the same file some washers that are useful to keep the rotating part of the servo in place.
Also uploaded some pictures.

Uploaded the file for the rotating servo attached to Arduino.
Uploaded some pictures also.
Has anyone used the files?

Some pictures with the arm almost done.

I got some servos to finish the arm. Put them all together and and just deciding which gripper to use.
Uploaded some pictures.
P.D: Sorry for my English.
