Sophia is different from previous robotic variants due to its human-like appearance and behavior. Unlike earlier robots, Sophia can mimic human gestures, facial expressions, and engage in simple conversations, making it more relatable and socially interactive. Its design incorporates features inspired by Queen Nefertiti, Audrey Hepburn, and Amanda Hanson, giving it a more natural and lifelike look compared to earlier, more mechanical robots. This allows Sophia to simulate social behaviors, making it capable of inducing emotional responses and interacting in a more human-like manner.
