The invention discloses a combined tetrahedral movable
robot which comprises six-fork vertexes from first to fourth, three-fork vertexes from first to fourth and
branch chains from first to eighteenth. The first six-fork vertex is connected with the first, second, third, seventh, tenth and thirteenth
branch chains. The second six-fork vertex is connected with the first, fourth, sixth, twelfth, fourteenth and eighteenth chain chains. The third six-fork vertex is connected with the second, fourth, fifth, eighth, fifteenth and sixteenth
branch chains. The fourth six-fork vertex is connected withthe third, fifth, sixth, ninth, eleventh and seventeenth branch chains. The first three-fork vertex is connected with the branch chains from seventh to ninth. The second three-fork vertex is connectedwith the branch chains from tenth to twelfth. The third three-fork vertex is connected with the branch chains from thirteenth to fifteenth. The fourth three-fork vertex is connected with the branch chains from sixteenth and eighteenth. After the connections are completed, the
robot represents the five-regular-
tetrahedron-combined appearance. The
robot can move on the ground in all directions by changing postures and can be used for reconnaissance, detection and the like.
