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.

| Out of the box | Among the most functional at its price: walks day one, remote and app control, demo motions, voice/LLM interaction, and a proven autonomous soccer stack (RoboCup 2025 KidSize champion lineage). Widely used for demos with zero code. | 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. |
| Development access | Open across ALL tiers (unlike Unitree R1): Python/C++ APIs, ROS 2, Booster Studio IDE, open-source RoboCup framework, and sim support (Isaac, MuJoCo, Webots, Gazebo). Tiers differ by compute, not by SDK lock. | 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. |
| Best for | Schools, RoboCup teams, and labs that want an affordable, fully open, competition-proven development platform. | 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. |
