EEZYbotArm MK3

thingiverse

This is a revolutionary 3D printed robotic Arm. It builds on the success of my previous two designs: EEZYbotARM and EEZYbotARM Mk2. It shares the same dimensions as the first one, making it incredibly cheap and fast to print. The main base requires a little more time to be printed. This version was created with the goal of replacing servo motors with economic stepper motors, and this is the result. During development I found the stepper motor to be a little weak for its purpose, so I redesigned the transmissions on vertical arms, and applied a modification from unipolar to bipolar stepper. As the previous two arms it has been designed without a specific purpose in mind, the aim is educational, providing suitable hardware that allows users to concentrate on exploring all its potential applications.
