How we placed it

The rule, not an opinion

Stages are worked out by published rules from the dated milestones above. We never rate robots, and no maker can pay to change a stage.

  1. 5

    Regulator-cleared or mass marketThis robot

    A regulator has cleared it where approval applies: FDA clearance or approval for a medical robot, a permit to run with no one aboard for a self-driving vehicle, or an FAA approval for routine drone flights. Or: Widely sold: sales in the hundreds of thousands, or a product category you can buy in ordinary shops.

    Placed by: Unitree's stock-market filing showed it sold 33,294 four-legged robots from 2023 to 2025, as it opened its share sale in Shanghai (10 Aug 2026).

  2. 4

    Paying customers

    Delivered to customers who pay for it, beyond a trial, or a paid service the public can use.

  3. 3

    Pilot

    Working with a named customer in a real setting, as a trial.

  4. 2

    Pre-orders

    Orders, reservations or deposits taken, with nothing delivered yet.

  5. 1

    Demo only

    Shown in videos, staged events or a factory, with no units working for customers.

What we couldn't confirm. The 33,294 figure covers all Unitree four-legged robots, including industrial models, not only the Go2. Other makers (such as Xiaomi and Deep Robotics) were not researched for this card.
