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.
What is in the crate

Hands sold separatelypriced by quote
Grippers are included only in the Standard Kit, starting at $829.99 with a 2GB Pi 5. The $729.99 Starter Kit has none; the $100 kit difference is not a separately sold hand accessory.

Reality check
It runs real ROS, but the hobby servos and Pi compute mean it is a teaching tool with a hard ceiling, not a path to research.
Can you get one, and what will it cost?
A planning estimate with machine, freight, duty, and tax shown separately.
Yes, with work: importable into United States.
US authorization: We found no public FCC ID for this model. Since 28 July 2026 a foreign-made robot can be sold into the US only under an FCC authorization from before that date, so ask the seller for its FCC ID, or its Supplier's Declaration of Conformity dated before 28 July 2026, before you pay.
Optional hands are excluded until a seller quotes them. Spare batteries and other accessories are excluded. Confirm compatibility and pricing with the seller.

Size to scale
Drawn next to a 1.80 m (5 ft 11 in) person. Every robot on the site uses this same reference, so you can trust the comparison at a glance.
AiNex: 41.5 cm / 1 ft 4 in, 2.45 kg
Footprint: 16 cm wide x 11 cm deep
What it does on day onewith zero programming
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.
Best for: Classrooms and self-learners who want to teach ROS and inverse kinematics on a real walking biped.
Documented uses
Teaching / education / Learn and tinker / Demo / showpiece
ROS, vision and gait tutorials support learning on a small walking platform.
The Starter Kit has no grippers. Custom learning activities require code; this is not a household worker.
Source reviewed 2026-09-09Assessment from published documentation, not an independent performance test. Applies to the configuration described above.
What it takes to developskills, gear, and SDK access
Python basics; ROS/Linux for deeper work. Everything runs on the included Raspberry Pi 5, no GPU workstation needed.
SDK 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.
