Twelve degrees of freedom robotic tetrahedron

The present invention discloses a twelve tetrahedral DOF robot assembly means includes four vertices (I, II, III, IV) and six branches (A1, A2, A3, A4, A5, A6), the vertex component I and three, respectively, a first flange, a third, a fourth branch (A1, A3, A4) is fixed by a pin; three vertices flange assembly and II, respectively a first, a second, a fifth branched (A1, A2, A5) is fixed by a pin; three vertices flange assembly and III, respectively the second, third, sixth branch (A2, A3, A6) is fixed by a pin; three on the vertices of component IV flanges, respectively, and the fourth, fifth, sixth branched (A4, A5, A6) is fixed by a pin; the same components of the four vertices (I, II, III, IV) and the size of the structure, according to six identical branches (A1, A2, A3, A4, A5, A6) structure and dimensions; through said connection means that more space can be ground attitude changes and fast-moving and steering.
