1. A mechanical finger comprising: a first phalanx pivotally connected at a proximal end to a base; at least a second phalanx pivotally connected at a proximal end to a distal end of the first phalanx; a transmission linkage between the base and the second phalanx, the transmission linkage comprising at least: a parallelogram configuration formed between the base, the first phalanx, the second phalanx, and the transmission linkage when the locking device selectively blocks the at least one joint, for the second phalanx to move in a constant orientation relative to the base when the locking device selectively blocks the at least one joint, to maintain the parallelogram configuration as the second phalanx moves.
