Unitree B2 Quadruped Robot w

A robot that weighs as much as a grown adult and still clears a 40cm stair is not what most people picture when they hear "robot dog". The Unitree B2 Quadruped Robot w is built for the jobs where a person would otherwise walk a long, cold, or awkward route: plant rounds, outdoor inspection, and heavy sensor carrying over uneven ground. It treats the walk itself as the working task, not as a demonstration.

The product is available through this page, by quotation.

Background

Unitree Robotics and the B2 line

Unitree Robotics is a maker of legged robots, and its quadrupeds range from compact teaching platforms to heavier industrial machines. On November 3, Unitree Robotics released the industrial quadruped robot B2, positioning it for real-world application work. The B2 sits at the working end of that range, where payload, endurance and weather resistance matter more than novelty.

The sources name two versions: the B2, which is the legged machine described on this page, and the B2-W, which adds wheels. For this page, the wheeled foot is listed as an option, and every figure below belongs to the B2.

Positioning and key technology

The B2 pairs strong joints with a swappable battery and a computing platform that can be opened for user development. Maximum joint torque is about 360N.m, which is what lets the robot stand under a load of 120kg or more and walk with more than 40kg. The sensing package is a 3D LiDAR, two depth cameras and two optical cameras, and it varies with the configuration you choose.

On the computing side, the standard configuration uses an Intel Core i5 for platform functions and an Intel Core i7 for user development. An Intel Core i7 or an Orin NX is available as an option. Software arrives through continuous OTA upgrades and updates, so the robot keeps improving after it is delivered.

Technical Specifications

The manufacturer has not published the payload mounting interface, the charging time, the noise level, the degrees of freedom or the contents of the box; they are confirmed at quotation.

How does the B2 cope with stairs, weather and long shifts?

Terrain is where a legged robot earns its place. The B2 climbs up and down stairs of 40cm in the forward direction, handles slopes steeper than 45°, and can jump more than 1.6m. Those figures describe a machine that treats steps, ramps and gaps as part of the route and not as reasons to turn back.

Weather matters as much as ground. The IP67 rating and an operating range of -20℃ to 55℃ mean the robot is not limited to dry, mild days indoors. A site that is cold at dawn and hot by noon falls inside that range, which is important for outdoor inspection teams in any climate.

The battery is 45Ah (2250Wh) at 58V, with a battery life of 4-6h. Walking without load, the robot runs for more than 5h and covers more than 20km. With a 20kg load, it runs for more than 4h and covers more than 15km. The battery supports quick change, so a spare pack keeps the robot in service while the first one charges, and autonomous charging solutions are optional for sites that want the robot to dock itself. The charger for the B2 is 58.8V 10A.

What makes the B2 different from the wheeled B2-W?

The B2 on this page walks on legs, and that is its strength wherever the ground is broken, stepped or unpredictable. Legs go where wheels cannot. The wheeled foot is listed as an option for the B2, and the separate B2-W version is built around wheels for sites with long, smoother runs.

If your route is mostly stairs, gravel and uneven surfaces, the legged B2 is the natural fit. If your route has long flat stretches, take a look at the Unitree B2-W Wheeled Quadruped Robot. Figures on this page belong to the B2 only and should not be read across to the B2-W. For teams that want navigation hardware bundled with the machine, the Unitree B2 Quadruped Robot with Navigation Kit Package is the related listing.

Who is the Unitree B2 Quadruped Robot w for?

Industrial operators are the first group: utilities, plants and facilities with rounds that are repetitive, remote or uncomfortable. The weather rating, the temperature range and the stair-climbing ability fit that kind of work.

Integrators and development teams are the second. The four gigabit Ethernet ports, four USB3.0 ports and the 12V, 24V and 5V power outputs give room to mount and power extra equipment, and the Intel Core i7 option for user development opens the platform to custom software. Research groups that need a strong legged platform for locomotion and perception work will find the same flexibility useful.

Buyers who need wheels should look at the B2-W. Buyers who are only starting out with a smaller, lighter robot may want to browse the Standard Quadrupeds category first.

What is the Unitree B2 Quadruped Robot w used for?

1. Inspection rounds: carries LiDAR and cameras through plants, yards and substations on a repeatable route.
2. Payload carrying: walks with more than 40kg, which suits sensors, tools or other equipment.
3. Stair and slope access: reaches decks, platforms and upper levels that wheeled robots cannot.
4. Outdoor work in harsh weather: operates from -20℃ to 55℃ with IP67 protection.
5. Custom development: uses the open computing platform and external interfaces to host user software and added hardware.
6. Research and training: serves as a legged platform for studying locomotion, navigation and autonomy.

Summary

The Unitree B2 Quadruped Robot w answers a simple question: what if the heavy, dangerous or tedious walk were done by a machine that does not tire quickly? With about 60kg of mass, a running speed above 6m/s, a walking load above 40kg, IP67 protection and hours of battery life, it moves the work from people to a legged platform.
