Abstract: An automated storage and retrieval system includes a multi-level storage rack and a material handling robot, where the multi-level storage rack includes a plurality of cuboid cells and the material handling robot is configured to navigate along a vertical direction or a horizontal direction from a first cuboid cell to a second cuboid cell. When the navigation from the first cuboid cell to the second cuboid cell is along a vertical direction, a set of second engagement structures disposed at corners of the material handling robot are mated with a set of first engagement structures disposed along structural columns of the first cuboid cell. A rotation of the second engagement structures drives the material handling robot to vertically move along the structural columns of the first cuboid cell.

Abstract: In an embodiment of the disclosure, there is provided a panel assembly for joining to a structure and method of making the same. The assembly has a first panel element having at least one first panel nonlinear edge, and has a second panel element having at least one second panel nonlinear edge, wherein the second panel nonlinear edge is designed to interlace with the first panel nonlinear edge to form a panel assembly with interlaced panel edgebands for joining to a structure. A width of the interlaced panel edgebands is reduced as compared to a width of adjacent panel edgebands formed by adjacent panel elements having linear edges, and the reduced width results in an overall reduced weight of the panel assembly and the structure to which the panel assembly is joined.
