Degrees of Freedom
The Shadow Dexterous Hand has been designed to have a range of movement equivalent to that of a typical human being.
The four fingers of the hand contain two one-axis joints connecting the distal phalanx, middle phalanx and proximal phalanx and one universal joint connecting the finger to the metacarpal.
The little finger has an extra one-axis joint on the metacarpal to provide the Hand with a palm curl movement.
The thumb contains one one-axis joint connecting the distal phalanx to the proximal phalanx, one universal joint connecting the thumb to the metacarpal and one one-axis joint on the bottom of the metacarpal to provide a palm curl movement.
The wrist contains two joints, providing flex/extend and adduct/abduct.
This means that the Shadow Dexterous hand has 24 joints all together, with 20 degrees of freedom.

Famous quotes containing the words degrees of, degrees and/or freedom:
“So that the life of a writer, whatever he might fancy to the contrary, was not so much a state of composition, as a state of warfare; and his probation in it, precisely that of any other man militant upon earth,—both depending alike, not half so much upon the degrees of his WIT—as his RESISTANCE.”
—Laurence Sterne (1713–1768)
“How have I been able to live so long outside Nature without identifying myself with it? Everything lives, moves, everything corresponds; the magnetic rays, emanating either from myself or from others, cross the limitless chain of created things unimpeded; it is a transparent network that covers the world, and its slender threads communicate themselves by degrees to the planets and stars. Captive now upon earth, I commune with the chorus of the stars who share in my joys and sorrows.”
—Gérard De Nerval (1808–1855)
“Freedom of the press is essential to the preservation of a democracy; but there is a difference between freedom and license. Editorialists who tell downright lies in order to advance their own agendas do more to discredit the press than all the censors in the world.”
—Franklin D. Roosevelt (1882–1945)
