Supplier
China's highest-volume legged-robotics maker — quadrupeds (Go2, B2), humanoids (G1, R1, H1) and an in-house component line (Dex5 hand, joint actuators, L2 LiDAR). Open SDKs and aggressive pricing make it the default first buy for research labs.

FAQ
B2 or Deep Robotics X30 for inspection?
Unitree wins on price and ecosystem; Deep Robotics competes on inspection-specific payloads, software and service depth (priced ~30% above comparable hardware). A genuinely fair fight — quote both.
Legs or wheels (B2-W)?
Where terrain allows, wheel-leg covers ground far faster; stairs and rubble favor legs. For large-perimeter patrol ask for both configurations in the quote.
