A continuum robot control device, configured to control operations of a continuum robot having a bendable portion that is bent by driving at least part of a plurality of wires, includes a kinematics computing unit that computes a driving amount l.sub.k1b of the at least part of the plurality of wires, based on a target bending angle that is a target value for a bending angle of the bendable portion, a compensation amount computing unit that computes a compensation amount for compensation of the driving amount l.sub.k1b, based on the target bending angle, and a displacement of one of the plurality of wires at the target bending angle, and an adding unit and position control unit that set a driving control amount of performing driving control of the at least part of the plurality of wires, based on the driving amount and the compensation amount obtained by computation.

The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. One example method includes providing a redundant degree of freedom (DoF) for an end effector joint of one DoF by driving the joint with two actuators, calculating a position displacement of the joint to effect a desired end effector movement in response to an input command, calculating a first movement of the two actuators based on the position displacement of the joint and a second movement of the two actuators based on a second control objective in a null space corresponding to the redundant DoF, and driving the joint according to the first movement and the second movement to effect the desired end effector movement while accomplishing the second control objective in the null space.
