Abstract: Systems and methods for path planning by creating a three dimensional weighted graph representing a physical area wherein the third dimension comprise planes, wherein each plane represents a time unit, further wherein nodes can be connected only between different planes.

Abstract: A method for retrieving content stored in a warehouse, the method may include: maintaining first content in boxes of a lowest shelf of a storage unit of the warehouse, while maintaining in boxes of higher shelves of the storage unit second content that is of less interest than the first content; accessing the boxes of the lowest shelf and providing the boxes to interfacing units, by a first robot; accessing the boxes of the higher shelves and providing the boxes to the interfacing units, by a second robot; wherein the first robot, when positioned at a lower position, is lower than a height of the lowest shelf, and wherein the second robot is higher than the height of the lowest shelf.

Abstract: Systems and methods for a modular warehouse system comprising: at least two modular stackable bins wherein said bins does not require structural support and may allow retrieval of at least one of said bins, regardless of its location in the pile, without changing said pile's order; at least two bin retrieval robots; at least one non-transitory computer-readable medium storing processor executable instructions on a computing device for warehouse management.
