The invention claimed herein presents a kit that allows the user to build a functioning model of the type of mechanical hand used in prosthetics and robotics. The finger segments 4 of each digit are connected in a fashion that results in adjustable joints. The completed hand opens and closes via motor and gearbox 8. (FIGS. 1 and 2). Limit switches 38 restrict travel of the fingers to the grip range of the human hand. The hand is operated using a electrical, radio, infrared or digital remote control system, with receiver 22 mounted in the hand and transmitter 28 concealed within a glove or cuff 30 which can be worn by the user (FIG. 2). This system allows the invention to be operated via motion of the user's hand/wrist 36, which actuates a switching means within said glove or cuff. Movement can also be activated via onboard control switch 24.
