Update on my Robot Arm build. Last time I've build axis 1 and partially axis 2 and 3. Now I have finished axis 2, 3, 4 and 5 and partially axis 6 and 7. Soon I will start testing. I am really curious about performance. I think this can be the most advanced 3D printed DIY Robot Arm. Also it is light, and thus can be used for humanoid robots.
