This model is based on Eezybot: http://www.thingiverse.com/thing:1015238
but with some improvements. One is that the base of the robot uses a stepper motor instead of a servo. Other changes are the situation of the servos in the arm.

Required material:

MG 90S servos (originals if possible) (3 units)
Unipolar stepper
Cable
M3 screws and nuts (for the base you can also use M4)
Arduino Sensor Shield
Arduino board
MiniJoystick
This is the code I've used, but you can get you own code instead: https://github.com/rachuism/Programacion_brazo/blo
