    • An improvement is set forth in a robotic arm structure which includes at least two links. .theta. motion is provided about a primary axis at the proximal end portion of the proximalmost of the links. R motion proceeds radially from the primary axis whereby the distal end portion of the distalmost of the links can be moved in a radially extending straight line. An end effector is pivotally mounted for rotation relative to the distal end portion of the distalmost link about an end effector axis which is parallel to the primary axis. The structure is improved by adding one or more a yaw motor, a roll motor and a pitch motor for rotating the wrist of the arm about the respective axes. A sensor array senses the R, .theta., Z and yaw, roll and/or pitch motions and creates and transmits electronic signals representative thereof to a computer controller which monitors and controls the R, .theta., Z and yaw, roll and/or pitch motions. Non-radial straight line motion and indeed, in certain embodiments any desired three-dimensional motion, is thereby enabled as is picking up of workpieces such as semiconductor wafers, flat panel displays and data storage disks, which are misaligned in cassettes or at workstations and/or are in cassettes which are misaligned and/or aligned and set up at an angle relative to the usual plane of operation of the arm.
    • 在包括至少两个连杆的机器人臂结构中提出了一个改进。 围绕最近端部的近端部分处的主轴设置θ运动。 R运动从主轴径向延伸,从而链节的最远端的远端部分可以沿径向延伸的直线移动。 端部执行器枢转地安装成相对于最远端连杆的远端部分围绕平行于主轴线的端部执行器轴线旋转。 通过添加一个或多个偏转马达,滚动马达和俯仰马达来改善该结构,以使臂的手腕围绕各个轴线旋转。 传感器阵列感测R,θ,Z和偏航,滚动和/或俯仰运动,并创建和发送代表它的电子信号到计算机控制器,该计算机控制器监视和控制R,θ,Z和偏航,滚动和/或俯仰运动 。 因此,非径向直线运动,实际上在某些实施例中,任何期望的三维运动都能够像在半导体晶片,平板显示器和数据存储盘等工件上拾取一样,这些工件在盒式磁带或工作站中是不对准的, /或在相对于通常的手臂操作平面成一定角度的未对准和/或排列和设置的盒中。
