EchoEar by Espressif: An Open-Source AI Kit for Voice and Smart Home Control Espressif has launched a new kit called EchoEar, a smart AI development kit. The demo application acts as a voice assistant. It listens to what you say, understands it, and responds naturally. It shows that it can go beyond talking like a human; it can even sing. The built-in conversational AI allows it to mimic human-like flaws and fillers like “like” and “you know”. The… |

DUAWLFIN, A Drone That Can Both Fly and Drive Using the Same Motors Researchers from UC Berkeley have developed a unique hybrid drone that both flies like a quadcopter and drives on the ground using the same motors. Unlike the average drone that needs separate motors or propellers to move on the ground, DUAWLFIN uses a clever mechanical system called a differential drivetrain to switch between flight and wheels. The spinning of propellers is not required while… |
