Shadow Hand - Degrees of Freedom

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:

    “Complete courage and absolute cowardice are extremes that very few men fall into. The vast middle space contains all the intermediate kinds and degrees of courage; and these differ as much from one another as men’s faces or their humors do.”
    —François, Duc De La Rochefoucauld (1613–1680)

    “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)

    “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)
