Intelligent desktop interactive robot based on eps32s3

This design is an intelligent desktop interactive robot. As the name suggests, it is an intelligent robot that can interact with people. A 2.4-inch LCD screen is used as an important channel for human-computer information interaction. It also has voice recognition and sound playback functions, making contactless interaction more convenient. The interface design adopts the open source LVGL 8 GUI framework and uses ESP32S3 as the main control chip. The current regional temperature can be displayed on the interface, and the sound can be broadcast through voice interaction. It also displays the dynamics of the EEWORLD forum, including the display of the daily number of posts and the total number of posts. Through voice interaction, the voice broadcast of the total number of posts can also be obtained. . And the onboard LED lights can be controlled by voice.
