ABSTRACT:
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.
