    • A structure, guidance, and drive assembly for translation of a robotic picker assembly may comprise a support frame having a front end, a rear end, and two opposed sides. The front and rear ends of the support frame are positioned in parallel, spaced-apart relation to a lateral axis, while the two opposed sides are positioned in parallel, spaced-apart relation to a longitudinal axis, the lateral and longitudinal axes defining a horizontal reference plane. The support frame includes a first elongate bearing surface that is located at about the front end of the support frame. The first elongate bearing surface extends between the two opposed sides of the support frame so that the first elongate bearing surface extends in a direction that is substantially parallel to the lateral axis and lies in a first bearing plane that is substantially parallel to the horizontal reference plane. The support frame also includes a second elongate bearing surface that is located at about the rear end of the support frame. The second elongate bearing surface also extends between the two opposed sides of the support frame and also extends in a direction that is substantially parallel to the lateral axis and lies in a second bearing plane that is substantially parallel to the horizontal reference plane. The second bearing surface plane is non-coplanar with the first bearing surface plane. A three point contact primary bearing system mounted to the robotic picker assembly is adapted to engage the first and second elongate bearing surfaces and allows the robotic picker assembly to be displaced within the support frame in a direction generally parallel to the lateral axis and along the horizontal reference plane. An actuator connected to the robotic picker assembly moves the robotic picker assembly to predetermined points along the lateral axis in response to commands from a control system.
    • 用于机器人拾取器组件的平移的结构,引导和驱动组件可以包括具有前端,后端和两个相对侧的支撑框架。 支撑框架的前端和后端位于与横向轴线平行,间隔的关系中,而两个相对的侧面被定位成与纵向轴线平行,间隔开的关系,横向和纵向轴线限定水平 参考平面。 支撑框架包括位于支撑框架的前端附近的第一细长支承表面。 第一细长承载表面在支撑框架的两个相对的侧面之间延伸,使得第一细长支承表面在基本上平行于横向轴线的方向上延伸并且位于基本上平行于水平参考平面的第一支承平面中 。 支撑框架还包括位于支撑框架的后端附近的第二细长支承表面。 第二长轴承表面也在支撑框架的两个相对侧之间延伸,并且还在基本上平行于横向轴线的方向上延伸并且位于基本上平行于水平参考平面的第二支承平面中。 第二支承面平面与第一支承面平面不共面。 安装到机器人拾取器组件的三点接触主轴承系统适于接合第一和第二细长支承表面,并允许机器人拾取器组件在支撑框架内沿大致平行于横向轴线并且沿着水平方向移位 参考平面。 连接到机器人拾取器组件的致动器响应于来自控制系统的命令将机器人拾取器组件沿着横向轴线移动到预定点。
