With the rapid development of electronics, household kitchen appliances are gradually becoming intelligent. To improve the well‑being of office workers and address challenges such as limited time for cooking rice, this paper proposes the structure and control system of a cooking robot. The system uses an STM32 microcontroller as its core and integrates IoT and other new technologies to enable interaction among the smartphone, cloud, and the cooking robot. It supports remote control and monitoring via a mobile app, and on‑device monitoring of the operating status or the cooking curve through a touch screen. Experimental tests show that the robot can automatically complete a series of operations, including rice metering, rice washing, and rice cooking, making the system more user‑friendly and intelligent.
