DEFINITION: A microhand is a miniature robotic end effector, which is a device or tool connected to the end of a robot arm. A microhand is designed to grasp, hold and manipulate objects in a manner similar to the functioning of a human hand but on a much smaller scale.A prototype microhand developed at the University of California, made of silicon wafers, measures approximately one millimeter (1mm) across when  …

MEMS DEFINITION (continued): …  its four "fingers" are closed. The moving parts are driven by pressurized gas, allowing use of the device under a variety of conditions. The device's small size and high precision have aroused interest among surgeons, who envision it as a potential tool for performing critical operations in the human body. A sophisticated microhand may incorporate an eye-in-hand system, to enhance maneuverability and precision. Components of such a system include a camera specialized for work at distances of a fraction of a millimeter and a lamp for use in dark environments, such as the inside of …
