Modern toy robots use Bluetooth Low Energy (BLE) to communicate with controllers and mobile apps. In this talk, you’ll learn how to go beyond traditional controls and use voice commands to interact with physical hardware. We’ll explore how the WebBluetooth API can send instructions directly to robots and how, by integrating it with the WhatsApp API, you can turn them into devices controlled by both voice and messaging. Through practical examples, you’ll see how to trigger movements, lights, and sounds using only your voice—creating interactive experiences that blend IoT, APIs, and real-time communication.
