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.
