ROBOT HAND

摘要

A robot arm includes an outer casing and three rotating members of different diameters coaxially disposed in the outer casing for relative rotation and rockably supporting the proximal end portions of three fingers. These fingers are rocked against the rotating members in a plane including a central axis of the outer casing and rotated to change the relative angles between the fingers by selectively rotating the members around the central axis of the outer casing to prescribed positions.
