The Michelangelo Hand is a fully articulated robotic hand prosthesis developed by the German prosthetics company Otto Bock and its American partner Advanced Arm Dynamics. It is the first prosthesis to feature an electronically actuated thumb which mimics natural human hand movements. The Michelangelo Hand can be used for a variety of delicate everyday tasks, and has been in use by military and civilian amputees in the United States and United Kingdom since 2011.
