This python script enables real-time control of a robotic arm in Blender. It works by reading the inverse-kinematics angles from the arm's armature and sending them through the serial port to an arduino controlling the physical arm.

It has been used to drive both M1R0 and Thor

The project has been simplified to provide an easy example of how to get data from blender and to send it to an arduino, and is ready to be used at once.

To start controlling the arm first upload the arduino code into the board. Then open Blender and press on "Run Script" and the play icon (as seen in the image below) and hover the mouse over the arm after pressing the "G" key ("Link3IK" must be selected).

    Dear Avarro

    Can you say me, wich Pin on the Adruino did you use for the Servos. Did you use a special motor?
    Thanks for your Feedback

      Hi, apparently I used pins 8 & 9, but you can change it on the code to whichever you like.
      The servos were pretty large, but I don’t remember the model, sorry. The robot’s repo is here: https://github.com/JavierIH/M1R0
