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:
“Always the laws of light are the same, but the modes and degrees of seeing vary.”
—Henry David Thoreau (1817–1862)
“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)
“I wish to speak a word for Nature, for absolute freedom and wildness, as contrasted with a freedom and culture merely civil,—to regard man as an inhabitant, or a part and parcel of Nature, rather than as a member of society. I wish to make an extreme statement, if so I may make an emphatic one, for there are enough champions of civilization: the minister and the school committee and every one of you will take care of that.”
—Henry David David (1817–1862)
