Is a mini 4-axis robotic arm. To be fully functional, It need to be programmed by a microcontroller, like Arduino or Raspberry-PI. The code can be find on internet, and there are many totorial on internet about how to control a stepper motor with arduino. It is a great proyect if you are into robotics, programming, and/or automatization.

Is design to use 5 stepper motor 28BYJ-48 5V DC, which are the most common economical stepper motor in the market, at least in my country, but it can be easily modified to fit almost any other stepper motor. Contactme if you want the CAD files, I used SolidWorks to model It.

This is a work in progress, I will be uploading improvement time in time.
