ABSTRACT:
A method for estimating the orientation of the machine which provides a motive power unit and a working tool, in which the working tool is pivoted to the motive power unit and carries a 3D sensor and a rotational angle sensor; the method includes collecting a buffer of positional data points from the 3D sensor and fitting these points to a circle; the method also may be used to provide computer control of the machine.
