PROBLEM TO BE SOLVED: To accurately control a manipulator at the tip of an insertion part even if the insertion part is curved intricately.SOLUTION: A manipulator system comprises: a soft insertion part 10; a manipulator 6 having a joint part which is driven at the tip of the insertion part 10; a drive part 7 for driving the joint part of the manipulator 6 at the base end side of the insertion part 10; a shape estimation part for estimating a shape of the insertion part 10; and a control part for controlling the drive part 7 based on the shape of the insertion part 10 estimated by the shape estimation part. The shape estimation part comprises: a plurality of detection objects 14 which are disposed in the insertion part 10 at intervals in a longitudinal direction of the insertion part 10; a position detection part 15 for detecting three-dimensional positions of the detection objects 14; and a shape calculation part for calculating the shape of the insertion part 10 by dividing the insertion part 10 into a plurality of sections SS arranged in the longitudinal direction based on the three-dimensional positions of the detection objects 14, which are detected by the position detection part 15.COPYRIGHT: (C)2015,JPO&INPIT【課題】挿入部が複雑に湾曲した場合においても先端のマニピュレータを精度よく制御する。【解決手段】軟性の挿入部10と、挿入部10の先端において駆動される関節部を有するマニピュレータ6と、挿入部10の基端側においてマニピュレータ6の関節部を駆動する駆動部7と、挿入部10の形状を推定する形状推定部と、形状推定部により推定された挿入部10の形状に基づいて、駆動部7を制御する制御部とを備え、形状推定部が、挿入部10にその長手方向に間隔をあけて複数配置された被検出体14と、被検出体14の3次元位置を検出する位置検出部15と、位置検出部15により検出された被検出体14の3次元位置に基づいて、挿入部10の形状をその長手方向に並ぶ複数のセクションSSに分けて算出する形状算出部とを備えるマニピュレータシステムを提供する。【選択図】図2
