1. A mechanical digit comprising:
a base comprising a fluid manifold, a first fluid port positioned at a perimeter of the fluid manifold, and a second fluid port positioned at a perimeter of the fluid manifold;
a carriage member rotatably coupled to the base:
a first phalanx movably coupled to the carriage member;
a first cylinder at least partially contained within the fluid manifold and fluidly coupled to the first fluid port;
a first piston slidably received by the first cylinder for translation along a first translation axis extending outside of the fluid manifold;
a first linkage that mechanically couples the first piston with the first phalanx, wherein the first linkage is rotatably coupled to the carriage member;
a second phalanx movably coupled to the first phalanx:
a second cylinder at least partially contained within the fluid manifold and fluidly coupled to the second fluid port;
a second piston slidably received by the second cylinder for translation along a second translation axis extending outside of the fluid manifold; and
a second linkage that mechanically couples the second piston with the second phalanx.
