Abstract

With the rapid development of smart hardware technology, traditional desktop pets are gradually evolving towards interactivity and intelligence. This intelligent desktop pet system uses the STM32F103C8T6 single-chip microcomputer as its core controller, and constructs a dynamic interaction system through the SG90 servo set, OLED display screen, and voice module. The hardware design adopts a modular architecture, supporting dual power supplies of 5 V USB and lithium battery. At the software level, the system is designed with a multi-task scheduling mechanism, combined with a preset action sequence control algorithm to simulate the pet's emotional states, realizing various realistic behavior patterns such as “happy” and “angry”. Users can trigger 12 preset actions through voice commands and Bluetooth control. The system has a short response time and small action angle error. It provides a reusable technical solution for the development of low-cost intelligent embedded system interactive devices, expands the application boundary of affective computing in the embedded field, and offers a low-cost and highly practical solution for the design of intelligent interactive devices.
