Abstract
A multi-articulated link knee joint includes: a knee unit in which an upper link unit rotates relative to a lower link unit by a multi-articulated link mechanism including a plurality of link units including the upper link unit and the lower link unit; a cylinder device for assisting the motion of the knee unit and moving in accordance with the rotation of the upper link unit; a position detector for detecting the distance from the lower link unit to the cylinder device; and an angle detector for obtaining the bending angle of the knee unit from the detected distance from the cylinder device.
Claims5
A multi-articulated link knee joint comprising:
- a knee unit in which an upper link unit is structured to rotate relative to a lower link unit by a multi-articulated link mechanism including a plurality of link units including the upper link unit and the lower link unit;
- an auxiliary driver structured to assist motion of the knee unit and to move in accordance with rotation of the upper link unit;
- a position detector structured to detect a relative position of the auxiliary driver relative to the lower link unit;
- and
- an angle detector structured to obtain a bending angle of the knee unit from the detected relative position of the auxiliary driver.
