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

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).

While the blender file is focused on a SCARA arm, the script works with regular arms as well. Here is a video of it driving Thor:

The Blender Institute team then worked four months on realizing the VFX for the film. Improvements were made to Blender’s motion tracker, camera solver, masking, Cycles, and color grading. Additional funding by cinegrid.nl made it possible to re-render and deliver the whole film in 4k resolution. This version was released in April 2013.
