AURA is a robotic arm that can be assembled at home for $50.

This model is designed for various applications, ranging from educational purposes to prototyping. It allows users to create, adapt, and improve their own robotic systems.

Specifications:

Degrees of freedom: 5
Weight: 520g
Maximum operative radius: 30cm
Maximum gripper width: 6.84cm

Construction: The model consists of 13 printable parts, 5 servos, and a microcontroller. Each part needs to be printed only once, except for the "Phalange medial" which is printed twice. The arm components A, B, and C are divided into several pieces for easier printing.

Printing recommendations: You can print the parts all at once or in sections and assemble them using cyanoacrylate. The axes are made from 3mm filament. Non-printable components include an Arduino Leonardo microcontroller and several servo motors.
