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/blob/master/Programacion_brazo.ino

For the moment it's a prototype, I've found some errors in the design I'll try to fix as soon as posible. Anyway this is an open source project so you can take the advantage of it and contribute to the community. Thank you for being patient.
