Robotic arm

thingiverse

I'm SuperRachu on Twitter and Instagram, @SuperRachu. You can also find me on YouTube at www.youtube.com/watch?v=DzUxRKjmcz8. This robot is based on Eezybot: http://www.thingiverse.com/thing:1015238, but I've made some improvements. One key change is that this model uses a stepper motor instead of a servo for its base. I've also rearranged the servos in the arm to make it more efficient. Here's what you'll need to build this robot: * 3 MG 90S servos (originals if possible) * Unipolar stepper * Cable * M3 screws and nuts (M4 will work for the base too) * Arduino Sensor Shield * Arduino board * MiniJoystick The code I used is available on GitHub: https://github.com/rachuism/Programacion_brazo/blob/master/Programacion_brazo.ino. You can use this or create your own - it's up to you! Right now, this is a prototype and I've found some errors that I'll fix as soon as possible.
