CONTINUUM ROBOT CONTROL SYSTEM AND CONTROL METHOD, AND PROGRAM
An object is to provide a mechanism that can ensure safe operation of a continuum robot. A block FTL calculates a target bending angle θ.sub.fFTL and a target rotational angle ζ.sub.fFTL of a following bending section on the basis of a target bending angle θ.sub.lt and a target rotational angle ζ.sub.lt of a distal-most bending section and a displacement of a base. A switch unit 330 selects the target bending angle θ.sub.fFTL and the target rotational angle θ.sub.fFTL of the following bending section obtained from the block FTL or a target bending angle θ.sub.lf and a target rotational angle ζ.sub.lf of the following bending section obtained from a block P.sub.l corresponding to following operating means.

CONTINUUM ROBOT, CONTROL METHOD OF THE SAME, AND STORAGE MEDIUM
In a wire-driven continuum robot, in accordance with a profile of a first bending angle regarding a bending angle of a follow-up bending section that corresponds to a forward movement of a continuum robot, and is set in accordance with an input first target bending angle of a distal bending section, a bending angle of the following-up bending section is controlled to reach the first target bending angle. Before a movement amount of a forward movement reaches a first movement amount, the control is performed as follows. More specifically, a profile of a second bending angle that is different from the profile of the first bending angle is set, and by a further forward movement of the continuum robot, a bending angle of the following-up bending section reaches the second target bending angle in accordance with the profile of the second bending angle.
