INTERACTIVE ROBOT

To provide an interactive robot excellent in stability accompanying change of posture.SOLUTION: An interactive robot 1 comprises a base part 11, a trunk part 12, arranged above the base part 11, which can turn in a horizontal direction, and a head part 13, arranged above the trunk part 12, which can turn in a vertical direction. The trunk part 12 has an abdomen part 121 near the base part 11 and a chest part 122 arranged near the head part 13. The abdomen part 121 turns around a shaft in a vertical direction with respect to the base part 11. The chest part 122 turns around a shaft in a direction perpendicular to an upper surface of the abdomen part 121 that inclines with respect to a horizontal surface. The head part 13 is formed in a shape in which a part of a sphere is partially hollowed, and turns around a shaft in a horizontal direction passing through a center of the sphere. No matter how the parts turn, a vertical line of center of gravity of the head part 13 never deviates from a contour line of the trunk part 12.SELECTED DRAWING: Figure 1 【課題】姿勢の変化に伴う安定性に優れた対話型ロボットを提供する。【解決手段】対話型ロボット１は、基台部１１と、基台部１１の上部に配置され、水平方向に回動可能な胴体部１２と、胴体部１２の上部に配置され、垂直方向に回動可能な頭部１３を有する。胴体部１２は、基台部１１側に配置される腹部１２１と、頭部１３側に配置される胸部１２２を有する。腹部１２１は基台部１１に対し鉛直方向の軸周りに回動する。胸部１２２は水平面に対し傾斜する腹部１２１の上面に垂直な方向の軸周りに回動する。頭部１３は球体の一部をくりぬいた形状をしており、その球体の中心を通る水平方向の軸周りに回動する。これらの部位がどのように回動しても、頭部１３の重心の鉛直線が胴体部１２の外郭線外に出ることはない。【選択図】図１
