The robotic apparatus is designed to act in a wider variety of manners, which will motivate the user of the robotic apparatus to purchase more products to the robotic apparatus. More specifically, a robotic apparatus (1) which acts autonomously recognizes a bar code (BC) or the like appended to a canned juice (100a) and acts in a predetermined manner. This is only enabled under a predetermined contract made between a product manufacturer and robotic apparatus manufacturer. The contract coverage is that the product manufacturer shall append the bar code (BC) to a specific product while the robotic apparatus manufacturer shall provide a robotic apparatus (1) which can act in a predetermined manner when having recognized the bar code (BC).
