determining coordinates Ota=[Oxta Oyta Ozta]T of the center O at the time ta, restoring the coordinates Ota=[Oxta Oyta Ozta]T to a global coordinate system, wherein the vector {right arrow over (Arm )} is translated to make a starting point of the vector Arm coincide with the Ota to obtain a translation {right arrow over (Dpm)}, at this time, an end point of the vector {right arrow over (Arm )} after the translation is a position of the FRCS.
