Delivered to United States: the import estimate (machine plus freight, Sales tax (0%), robot duty, and broker), or a seller in your own market where one lists the machine for less. Accessories excluded. Check configuration and request a seller quote on each robot's datasheet.
About 40% on China-origin collected today: the 2.5% MFN base, 25% Section 301 List 1, and the 12.5% Section 301 forced-labor duty effective 24 Jul 2026 with no expiry. It began the same morning the 10% Section 122 surcharge lapsed, so the total rose from about 37.5% rather than falling to 27.5%. Confirm the live rate before ordering.

| Hands | Hands sold separately | Grippers, not dexterous hands | No hands, none offered |
| Out of the box | Walks with self-stabilizing inverse kinematics, follows lines, tracks objects, and grasps (Standard Kit), controlled from a phone app or gamepad. Works day one without programming. | Polished toy-grade demos day one: walking, color recognition, target tracking, ball kicking, gesture control, and voice interaction with a multimodal LLM. Fun out of the box with zero programming. | A genuinely agile walking robot day one: remote and app teleop, pre-trained demo motions (dancing, kung-fu), and onboard voice-and-image AI interaction. But on the base and Air tiers, that is all it will ever do, because development is locked. |
| Development access | Real ROS with Python, OpenCV, and Gazebo simulation. Hobby servos and Pi compute cap research use, but it is genuine ROS, not a toy app. | Python SDK on the Pi with OpenCV and open tutorials. NOT ROS-based (the ROS Hiwonder humanoid is AiNex). Firmly a hobby and classroom robot. | Two-class system: R1 Air and R1 are closed consumer units with no secondary development. The R1 EDU unlocks Unitree SDK2, ROS 2, and a Jetson Orin NX. |
| Best for | Classrooms and self-learners who want to teach ROS and inverse kinematics on a real walking biped. | K-12 STEM programs and hobbyists who want fun AI demos out of the box. | Anyone who wants an affordable, genuinely walking humanoid for demos, events, or a first taste of the category. |
