Abstract: Anthropomorphic hand comprising: a palm; a metacarpus; a thumb; four aligned fingers constrained to said palm, each comprising a proximal phalanx, a middle phalanx and a distal phalanx; a motor; a plurality of differential stages which transmit motion from said motor to said aligned fingers and to said thumb: a first stage whose planet carrier is moved by said motor and whose sun gears move planet carriers of a second and a fifth stage, sun gears of the second and fifth stages being integral to the planet carriers of a third and a fourth stage, whose sun gears move four gears having axes coincident with the axes of rotation between the aligned fingers and the palm; sun gears of the fifth stage being configured to rotate said metacarpus and a gear having axis coincident with the axis of rotation between the proximal phalanx of the thumb and the metacarpus.

Abstract: Anthropomorphic robotic hand comprising a palm and a metacarpus configured to rotate with respect to said palm around an axis of rotation; four fingers substantially aligned and constrained to said palm and a finger opposable to them, each one of said aligned fingers comprising at least a proximal phalanx, a middle phalanx and a distal phalanx, and said opposable finger comprising a proximal phalanx and a distal phalanx, the proximal phalanges of each one of said aligned fingers being hinged to said palm in respective axes of rotation and the proximal phalanx of said opposable finger being hinged to said metacarpus in a respective axis of rotation; a motor; a plurality of bevel gear differential stages which transmit motion from said motor to said aligned fingers and to said opposable finger.
