World in Motion 🕹️ on Instagram: "This is a real research prototype focused on reproducing human speech using a physical mouth rather than digital audio output. The system relies on soft silicone lips, artificial skin, and mechanical actuators to replicate the movements of a human mouth during speech. Sound is produced through controlled airflow and vibration, closely resembling the mechanics of a real human vocal tract. These robotic mouths are primarily developed in Japanese research laborato

Grow As Entrepreneurs on Instagram: "Elon Musk emphasizes that real progress starts with a working prototype, not a polished pitch deck. Ideas can look perfect on 20 slides, but only a tangible product proves feasibility. Even a rough, early version carries more weight than forecasts or diagrams. A primitive prototype reduces uncertainty by showing what actually works, not what might. History supports this approach. From SpaceX’s early test failures to Tesla’s first road-ready models, iteration
