About the Unitree B2 Protective Bracket
The Unitree B2 protective bracket is a freestanding commissioning gantry for Unitree's industrial quadruped — an official Unitree accessory that protects the B2 through setup, testing and development work. Instead of attaching to the robot, the frame stands on its own casters around the work area, adding a layer of protection through exactly the sessions when an industrial robot is most exposed.
Commissioning is when hardware takes its knocks. First power-ons, new locomotion code, sensor payloads and calibration runs all carry fall and bump risk, and on a work-site robot the cost of a damaged iteration is measured in schedule, not just parts. Teams running the B2 through development keep the Unitree B2 protective bracket around the test area so those sessions stay recoverable.
One product, one version — there is nothing to configure. The Unitree B2 protective bracket fits the B2 and the wheeled B2-W.
What Is the Unitree B2 Protective Bracket?
The Unitree B2 protective bracket is a portal frame that stands on its own wheels: two vertical columns, each mounted on a wheeled foot, spanned at the top by a pair of parallel rails. A cross rail sits clamped across the double rails — repositionable along the frame's width, so the working gap between the columns stays completely open for the robot, the payload and the people around it. Nothing attaches to the B2's body; the frame defines and covers the work area instead.
Across listings the product appears under close names — protective bracket, protection bracket, commissioning bracket. They all describe this one freestanding gantry. It is one product in one version: no variants, no configuration, no add-ons to price out.
Not the LiDAR Bracket From the Navigation Kit
Two different Unitree products share the "protective bracket" name around the B2. The B2 navigation kit includes a protective bracket that shields its LiDAR sensor — a small sensor mount, not this product. The Unitree B2 protective bracket on this page is the freestanding commissioning gantry. Checking the product form before ordering avoids the mix-up.
What the Unitree B2 Protective Bracket Is For
The Unitree B2 protective bracket is commissioned alongside the robot and stays in service through the whole development cycle. It matters most in the sessions where an industrial quadruped is least predictable:
- Setup and first runs — power-on checks, payload mounting and early gait tests, when the robot and the team are still learning each other
- Software validation and calibration — locomotion tuning, sensor calibration and diagnostics that repeat the same risky motion until it is right
- Maintenance and service days — recurring hands-on work around the robot, where a defined work zone keeps bumps and knocks off the hardware
Which Robots Does the Unitree B2 Protective Bracket Fit?
The Unitree B2 protective bracket is built for the B2 platform and fits both of its configurations: the legged B2 and the wheeled B2-W, with the same freestanding gantry serving each. Unitree's other robots use their own supports — the Go2 quadruped carries its own protection bracket, and the humanoid lines have their dedicated gantries.
- Fits: Unitree B2
- Fits: Unitree B2-W — the same freestanding gantry
- Other platforms: Go2, G1 and R1 use their own supports

Shipping & Service
The Unitree B2 protective bracket ships as an oversized parcel by courier — plan for a larger delivery than a hand-carry accessory. The frame wipes clean, and its casters roll it into a corner of the work area whenever the B2 is out on patrol. Every unit is 100% quality-inspected before it ships, so it arrives in perfect working order.
