Every quarter more operations teams ask the same question: can a robot dog actually do this work?
The Unitree B2-W is one of the most practical platforms for stock and inventory counts in offshore wind farms. It carries sensors where people should not go, keeps working through long shifts, and logs everything for later review. Below is the realistic picture for teams working in offshore wind farms.
Why a robot dog fits offshore wind farms
Offshore wind farms are dull, dirty or dangerous to inspect by hand. Stairs, confined spaces, live equipment and weather all slow people down and raise risk. A legged robot walks those paths autonomously and returns with a consistent record every time.
- Repeatable routes mean defects are caught on the same schedule, not when someone remembers.
- Live video and telemetry reach the control room without a person on site.
- The B2 keeps working in heat, cold and confined air where people need breaks.
- Data is timestamped and geo-tagged, which simplifies compliance and audits.
What the Unitree B2-W brings to stock and inventory counts
Consider the day-to-day reality, not the launch reel. The B2-W adds wheels to the B2 legs, hitting 10 m/s on roads while still climbing stairs and curbs.
- Roughly 4–5 h of runtime per charge, enough for a full shift with a spare pack.
- Up to 10 m/s top speed for covering ground quickly between checkpoints.
- 40 kg payload for cameras, thermal imagers, gas sensors or small deliveries.
- Onboard 4D LiDAR perception for obstacle avoidance and autonomous navigation.
- Ingress protection is IP67, so rain, mud and dust are part of the working day rather than a reason to stop.
A typical deployment
- Survey the site and mark no-go zones with the operator app.
- Let the robot build a map with SLAM on its first walk.
- Save a patrol or inspection route and schedule it.
- Review the captured images, thermal frames and alerts after each run.
- Tune the route as the team learns what matters most.

Cost and payback
A Unitree B2-W starts around $20,000 and scales with compute and payload options. For most offshore wind farms teams the payback is measured in reduced site visits, faster incident response and lower risk to staff rather than headcount replacement.
Frequently asked questions
Is the Unitree B2-W safe around people?
Yes for supervised use. It detects obstacles and stops or routes around them; sites still keep a trained operator in the loop for the first runs.
Do I need a specialist to run it?
Not for routine patrols. Mapping and route setup take an afternoon; daily operation is app-driven. Specialists are only needed for custom code.
