Provided is a manipulator system including: a manipulator that has an insertion section composed of a flexible section and a bending section and that has a bending-section drive unit for driving the bending section; an operation input unit; a flexible-section shape detecting unit and a bending-section shape detecting unit that detect curved shapes of the flexible section and the bending section, respectively; compensation-value setting units that set a compensation value on the basis of the curved shape detected by each of the shape detecting units; and a control unit that generates a curvature control signal for driving the bending-section drive unit according to an operating instruction input via the operation input unit and furthermore corrects the curvature control signal using the compensation value and transmits it to the bending-section drive unit.
