Abstract: An articulated robot arm comprises a plurality of skeleton links. Motorized joint units forming joints between adjacent ones of the skeleton links such that the skeleton links of the adjacent ones are rotatable relative to one another. One or more skin shells are provided for the skeleton links, the skin shell forming a non-structural skin around the at least one of the skeleton links.

Abstract: A mechanical finger for a mechanical hand, has: a proximal phalanx pivotably mountable to a support of the mechanical hand to pivot relative to the support about a finger pivot axis; a distal phalanx pivotably connected to the proximal phalanx via a first living hinge to pivot relative to the proximal phalanx about a first pivot axis; and a skeleton member pivotably connected at one end to the distal phalanx via a second living hinge to pivot relative to the distal phalanx about a second pivot axis offset from the first pivot axis and at another end operatively connected to an actuator of the mechanical hand to be selectively movable by the actuator to pivot the distal phalanx relative to the proximal phalanx and to pivot the distal phalanx relative to the support when the finger is in use.
