Unitree Go2 vs Unitree B2
Both are Unitree quadrupeds, but they are not in the same league — one is an accessible developer workhorse, the other an industrial payload platform at ~60× the price. Here is where each actually fits.
Spec-by-spec
Where they actually differ.
| Spec | Unitree Go2 | Unitree B2 |
|---|---|---|
| Price (approx) | ~$1,600 (Air) | ~$100,000 |
| Payload | ≈ 8 kg (loadable) | 40 kg+ sustained, 120 kg static max |
| Weight | ≈ 15 kg | ≈ 60 kg |
| Top speed | ≈ 2.5 m/s | ≈ 1.6 m/s (loaded) |
| Battery (active) | 1–2 hr real, 5–10 standby | 4–6 hr under work |
| Ingress protection | IP67 | IP-rated industrial |
| Best for | R&D, inspection, education | Industrial payload, all-terrain |
| SDK | unitree_sdk2 | unitree_sdk2 |

Verdict
The honest answer.
Pick the Go2 for R&D, inspection, education, and light field work where ~15 kg and IP67 are enough. Pick the B2 only when you genuinely need 40 kg+ sustained payload, IP-rated industrial endurance, and have the budget to match.
