In the world of robotics, voice recognition is a hot topic. Imagine controlling a robot simply by using voice commands. Sounds exciting, right? With the advent of technology and advancements in microcontrollers, it is now possible to build a voice-recognition robot at home. In this blog, we will show you how to design and build a voice recognition robot using the XIAO nRF52840 Sense, a powerful microcontroller with a built-in microphone.
🌟 About the Project
In this project, we will use the XIAO nRF52840 Sense as the main processor and build a robot that can be controlled using voice commands. The micro_speech library will be used to recognize the voice commands and the received commands will be displayed on an OLED screen. With this project, you will learn how to design a basic robot that can be controlled using voice commands.
🎯 Features
- • 4 Different Voice Commands
- • Show all received commands on an OLED Display
🧰 Getting Started
To build this voice recognition robot, you will need the following components:
- • XIAO nRF52840 Sense
- • DRV8833 Dual Motor Driver
- • OLED 0.96 SSD1306
