Zeno

Zeno is a compact humanoid robot engineered by Hanson Robotics for human-robot interaction research, especially autism therapy and education. Standing at child-like proportions around 43-56 cm tall, it features advanced **Frubber** skin for lifelike facial expressions driven by 32 simulated muscles, enabling emotional responses like smiling and frowning. Equipped with binocular 720p stereo vision at 30 fps for face recognition and tracking, plus 8 microphones for speech recognition across 26 languages, Zeno engages in natural conversations using AI-driven speech synthesis. Its 37 degrees of freedom allow arm movements, walking, head gestures, and eye expressions with moving eyelids. Powered by Dynamixel RX-28 servos and an open-source platform with Massive Software AI for navigation and autonomous behaviors, Zeno responds organically to its environment, making it ideal for social skill development, therapy sessions, and interactive learning in controlled indoor settings.
