In DH, the Z axis always goes along the direction of variability. For a rotational (revolute) joint, that means Z is the axis of rotation. For a translational joint (prismatic) the Z axis is in the ...

I don't think that you will be able to do this, given the limitations of an IMU. The main limitation being any kind of position or translation data. With angluar rotations you have the equations ...
