Full price history
| Price | Date | Variant | Source | Note |
|---|---|---|---|---|
| Contact | 2026-10-17 | B1 | Unitree official store | shop.unitree.com/products/unitree-b1 shows $100,000.00 USD with the stock label 'Ready to ship' and 'Customize products according to your needs'. The same $100,000 figure appears on the B2, B2-W, A2 and H2 Plus shop pages, so it is read as a placeholder; that reading is an inference, the page itself does not say so. No amount recorded from this page. |

Maverick Drone lists a pre-owned unit at USD 39,600 (not recorded as a purchase price); MYBOTSHOP.de says 'Price on request'. |

Key facts
- Official spec table (unitree.com/b1, 2026-10-17): standing 1126 x 467 x 636 mm, folded 1202 x 467 x 297 mm; about 50 kg with battery (battery about 5 kg).
- Continuous walking load 20 kg (Unitree recommends keeping the carried weight within 20 kg), maximum standing load 80 kg. Endurance: 5 h standing, 2 h continuous walking without load (ideal conditions). battery_hours holds the 2 h walking figure.
- Battery: lithium, 18,000 mAh, 51.8 V rated, 932.4 Wh, 1-2 h charge; battery working temperature -5 to 45 C (no robot operating range is given). Max stair step 20 cm.
- Expansion board: 7 x Gigabit Ethernet, 4 x RS485, 5 x USB, 4 x CAN; 12 V / 24 V power output. Over-temperature and over-current protection.
- Speed, DOF, joint torque and SDK details are not on the official page, so they are left empty rather than inferred.
- Older generation of Unitree's industrial quadruped line (the B2, unitree-b2, is the newer model). Unitree's shop shows $100,000 and 'Ready to ship' (likely a placeholder, inferred from the identical figure on other industrial models); the UK reseller IRED lists GBP 54,804 and marks the product title 'EOL'. Status stays 'available' because the maker's own shop and page still list it; IRED's EOL label is a reseller label, not a Unitree statement.
