PrimeBOT Q1 (Qiyuan Q1, 'Explorer' edition) is PrimeBOT's first personal humanoid robot, designed as a companion for learning, play and everyday life. It stands 88 cm tall (a 'golden' size suited to home spaces and interaction with children), is light and portable, and moves smoothly and naturally — it can take the user's hand and walk alongside them.

Q1 emphasizes embodied intelligence: it offers full-modal perception (voice, vision, touch, force control, posture, space) and expressive communication (speech, facial expression, body motion). A long-term memory architecture means it gradually comes to understand the user's preferences and habits. Six personas are available (e.g. storyteller, science explorer, historian, poet, engineer, thinker), each with its own voice, expressions and set of movements.

For children, Q1 acts as an educational partner: embodied-intelligence programming, scenario-based English conversation practice, and storytelling and encyclopedic conversations. Personalization is handled through the PrimeFLOW tool — the robot's appearance, movements and personality can be defined with a single sentence or image.

Q1 is also a professional platform for developers: it exposes an SDK, HDK and API, lets users plug in their own or open large models, is compatible with the ROS/ROS2 ecosystem, and provides joint-level motion-control interfaces plus open base motion models. Safety features include anti-pinch joint design (precise travel limits, multi-directional sensing, and stop-on-contact).
