A method of determining hysteresis according to an example embodiment may include capturing a real-time image of the surgical robot driven according to a drive input, and measuring a drive angle of the surgical robot by comparing the real-time image to a previously rendered image data set of the surgical robot, and calculating a difference between the drive input and the measured drive angle.

Method of determining hysteresis of surgical robot, method of compensating for the same, and endoscopic surgical apparatus

A flexible drive manipulator according to an example embodiment may include a proximal portion, a plurality of joint portions drivably connected from an end of the proximal portion with respect to a longitudinal axis, a distal portion connected to an end of the plurality of joint portions, a pair of drive wires passing through the plurality of joint portions in parallel along the longitudinal axis, the pair of drive wires configured to drive the plurality of joint portions in a rotational direction of rotation with respect to a transverse axis perpendicular to the longitudinal axis, and a fixing wire passing through the plurality of joint portions in a shape of converging along the longitudinal axis, the fixing wire configured to adjust rigidity of the plurality of joint portions.
