The crafting upgrade allows robots to craft shaped and shapeless recipes using items in their inventory. When crafting, the top-left 3x3 grid in the robot's inventory is used as the crafting grid. Items have to be arranged according to the recipe. Results will be placed back into the robot's inventory. As with picking up items, the result will be placed into the selected slot; failing to do so will place the item in the next available empty slot. If no inventory space remains, the result will be dropped into the world.
