Claim 8:
9. The grid frame of claim 2, wherein:
the second X-direction rail has a second X-direction divider that extends in the X-direction and protrudes from the second X-direction rail to divide the second X-direction rail along a center of the second X-direction rail into a first part and a second part,
the second X-direction divider is configured to engage the second pair of wheels to guide movement of the second pair of wheels in the X-direction along the first part of the second X-direction rail, the second X-direction divider providing a third space at one end of the second X-direction divider for the fourth pair of wheels to roll in the Y-direction through the third space past the second X-direction divider,
the second Y-direction rail has a second Y-direction divider that extends in the Y-direction and protrudes from the second Y-direction rail to divide the second Y-direction rail along a center of the second Y-direction rail into a first part and a second part, and
the second Y-direction divider is configured to engage the fourth pair of wheels to guide movement of the fourth pair of wheels in the Y-direction along the first part of the second Y-direction rail, the second Y-direction divider providing a fourth space at one end of the second Y-direction divider for the second pair of wheels to roll in the X-direction through the fourth space past the second Y-direction divider.
