2.6<\/b> Spherical and two Dimensional Space<\/h1>\n

Although we have not restricted the general degree-of-freedom equation for any particular space, the given examples were concerned with planar or spatial mechanisms where the degree-of freedom of space was 3 or 6 respectively. Another three dimensional space is the spherical space in which the links are restricted to move in concentric spheres (the degree of freedom of space is three). Such mechanisms are usually identified if all the revolute joint axes intersect at one point. A good example is the Hooke’s joint (sometimes it called Cardan joint). Three different Cardan joint construction are shown below.<\/span><\/p>\n
