Abstract: The invention is directed to a prosthesis which includes first and second members pivotally coupled together and two links which are pivotally coupled together with one link being pivotally coupled to the first member and the other link being pivotally coupled the second member. A control mechanism is provided which is pivotally coupled to the first member and the pivotal connection of the two links to move the two links and hence the second member relative to the first member. The first member may be coupled to a person to allow the prosthesis to serve in one embodiment as an arm or as a portion of an arm and in another embodiment to serve as a leg or as a portion of a leg.

Abstract: The apparatus has four links pivotally coupled together. First and second links each includes a first portion having an angular portion extending therefrom at an angle of between 120-135 degrees. The first link is pivotally coupled to the angular portion of the second link; the third link is pivotally coupled to the second link at about the juncture of its angular portion and its first portion; and the fourth link is pivotally coupled to the third link and to the first link at about the juncture of its angular portion and its first portion. The first portion of the second link is employed for holding a tool or a utility device thereto. A first linear actuator is pivotally coupled to the pivotal connection between the third and fourth links and a second linear actuator is pivotally coupled to the angular portion of the first link. The first linear actuator can impart linear movement to the second link in a given direction and the second linear actuator can impart linear movement to the second link in a different direction. The two linear actuators when activated simultaneously can impart a curvilinear trajectory to the second link. The effective length of each of the first and third links between their pivotal connections is equal to R and the effective length of each of the second and fourth links between their pivotal connections is equal to r. The ratio R/r is equal to a magnitude of 3 to 7.
