An Automated Storage and Retrieval System (ASRS) is like a big box full of shelves and drawers that stores items you might need on a regular basis. A robot helps move things around and get items from the boxes. The robot can go up, down, left or right and push or pull items from the shelves and drawers. The robot is special because it can carry and move items very quickly, making retrieval a lot faster and easier. Items can be organized and stored in an ASRS at a much lower cost than other storage methods. ASRS also uses less space because it can store items in a much smaller area than a warehouse or a shop.
