Abstract
An jointed tail of a pet robot can be configured simply and driven to curve freely and autonomously by fitting an jointed cylindrical member around outer circumferences of two wire portions and composed of a wire which is folded nearly into a shape of a hair pin, rotatingly driving two driven ends and on a side opposite to a tip of the two wire portions and connected to each other around an X axis and a Y axis with a differential gear mechanism and moving and controlling two driven ends and reversibly in an axial direction at a swing limit position around the X axis, thereby autonomously curving a tip of the wire
