Summary:To achieve a robot arm which has high degrees of freedom in motion and less restrictions on operations.SOLUTION: A robot arm 1 includes: a plurality of links L which can individually control lengths; a joint J such as a ball joint for connecting the links L; and a covering section 12 which covers the whole. An operation like a human tongue can be performed as a whole. For instance, when the link L along a longitudinal direction is extended on a lower surface side and the link L along the longitudinal direction on an upper surface side is contracted, the robot arm 1 can be rounded so that a side face view shape becomes a U-shape. Alternatively, when the link L along a right and left direction is extended on the lower surface side and the link L along the right and left direction is contracted on the upper surface side, the robot arm 1 can be rounded so that a front face view shape becomes a U-shape. Alternatively, when the link L along a vertical direction is extended and the link L along the right and left direction is contracted, a cross section of the robot arm 1 can be rounded and thickness of the robot arm 1 can be increased.SELECTED DRAWING: Figure 1 【課題】運動の自由度が多く、動作の制約が少ないロボットアームを実現する。【解決手段】ロボットアーム1は、長さを個別に制御可能な複数のリンクLと、リンクLを連結するボールジョイントなどのジョイントJと、全体を覆う被覆部12とで構成されている。そして、全体で人間の舌のような動作が可能である。例えば、下面側において前後方向に沿うリンクLを伸ばし、上面側において前後方向に沿うリンクLを縮めれば、側面視形状がU字型になるようにロボットアーム1を丸めることができる。或いは、下面側において左右方向に沿うリンクLを伸ばし、上面側において左右方向に沿うリンクLを縮めれば、正面視形状がU字型になるようにロボットアーム1を丸めることができる。或いは、上下方向に沿うリンクLを伸ばし、左右方向に沿うリンクLを縮めれば、ロボットアーム1の断面を丸くして、ロボットアーム1の厚みを増すことができる。【選択図】図1
