In our EC service called "Cookpad Mart", we develop Ruby x IoT system which not just works but works with reliability.
By the way, do you cook? Is it easy to get very fresh meats, fishes or vegetables around your home? Cookpad Mart makes it possible for customers to purchase fresh foods directly from farmers, meat shops and fish stores. We deliver ordered foods to pick-up points near your home, so you can pick them up anytime you like, without waiting for the delivery at your home or paying delivery fees.
To deliver fresh foods in the day of orders, we built a new distribution system consisting of several IoT devices: label printing devices, temperature sensors, location sensors and label readers.
In this talk, I explain our development of the label printing system. We set up label printing devices at all sellers’ shop and print labels for each food every day. We have to print the labels without any failures because they are for sellers, deliverers and customers to sort or to pick up foods, but it is difficult to monitor and to control many such edge devices like printers. Then, we solved it with a simple idea. I will talk about how to make the label printers reliable with Ruby and IoT technology.
