Movement, as consequence of the action is controlled through the friction between the support joint and the stage floor.

- the movement is expressed in 6 dimensions:

      - 2 are the x and y coordinates where the plumb line from the waist (centre of gravity) intersects with the floor
      - 1 is the height of the waist above the stage, along the plumb line
      - 1 is the rotation of the waist (hips and chest) relative to the front of the stage
      - 2 are the rotation of the waist (hips and chest) relative to the plumb line,
            where forward_leaning and sideways leaning are relative to the rotation of the waist

- to calculate the movement we need the geometry based on the joint angles.
