AURA




AURA is the All Users Robotic Arm that you can create at home for 50$. 



Here we see a whole 3D printable robotic arm, with a really cheap raw material. It has been programmed   to be intuitive and easy to use. All the programs needed for its development are free and easy to get.

We can divide the pieces of this arm in two groups: the printable ones and the electronic parts.
The printable parts are easy to get if you have acces to a 3D printer. If you do not, there are services that can print your pieces and send them to you. You can get all the electronic parts for a good price  by using big internet dealers like hobbyking or dealextreme.
The robotic arm moves through five servos controlled by a microcontroller. They are listed below:

Arduino Leonardo (micocontroller)
Servo Corona 939MG (Servo m)
Servo HK15288A Analog BB/MG (Servo beta)
Servo VS-11 Vigor Extra Large  (Servo alpha)
Servo Turnigy TGY-R5180MG (Servos omega and gamma)







To get all the files for free, and for more information related to this robot go to the download section







Specifications:
Degrees of freedom : 5
Weight: 520g
Maximum operative radius : 30cm
Maximum gripper width : 6,84 cm
Total cost : 39,83 euros (around 50$)
***(The price can change with time or depending the matirial you use)***








Let's build it: If you want to have your own AURA robotic arm, here are some steps you can follow.

    1. On the original design there are no screws nor bolts, all the parts are 3D printed and the axis between them, when needed, can be made with the raw material of the 3D printer ( http://www.youtube.com/watch?v=WqNxYHWpYko ) if you don't have the acces to this material or you just don't like the idea you sustitue this axis for the screws that best fit, but there are no specific ones
