Optical fiber estimation feedback control method of consecutive type robot

The invention relates to an optical fiber estimation feedback control method of a consecutive type robot, in particular to a shape feedback control method of the consecutive type robot. N consecutive type joints are connected in series to form a motion controller of the consecutive robot. N is a positive integer and is equal to 1 and 2..., and the motion controller of the consecutive robot sends motion orders to a joint executer. The joint executer receives the motion orders and drives the joints to bend. A shape sensor arranged on the joints real-timely detects bending curvature value of the joints at the same time and feeds back the bending curvature value to the motion controller. Consequently, motion precision and practicality of the consecutive type robot are effectively improved.
