Unitree B2 Quadruped Robot with Navigation Kit Package

Most robots are designed for the demonstration; the Unitree B2 Quadruped Robot with Navigation Kit Package is designed for the long round at the end of the day, when the stairs are wet, the air is hot and the route is still not finished. It is an industrial legged platform that publishes its endurance, load and protection figures plainly, so a buyer can judge the work it can do before asking for a quotation.

This product is available through this page, by quotation.

Background

Unitree Robotics and the B2 lineage

Unitree Robotics is a quadruped robot maker whose range runs from compact education dogs to heavier industrial machines. On November 3, Unitree Robotics released the B2 as a new industrial quadruped robot, positioned to lead the global quadruped robot industry application. The B2 sits at the working end of the range, well away from the lighter platforms meant for teaching and demonstration.

The family includes a wheeled sibling, the Unitree B2-W Wheeled Quadruped Robot, and the base platform is listed separately as the Unitree B2 Quadruped Robot. This page covers the B2 with the Navigation Kit Package, which is aimed at teams that want sensing and navigation capability alongside the legged body.

Positioning and key technology

The B2 is built around strength and endurance. The maximum joint torque is about 360N.m, and the robot carries a 45Ah (2250Wh) battery at 58V. It can stand under a load of 120kg or more and walk with a load above 40kg, which puts it in the class of machines that carry real equipment, not only a camera.

Perception is handled by a 3D LiDAR, two depth cameras and two optical cameras, and the exact set varies with the configuration. For computing, the standard configuration pairs an Intel Core i5 for platform functions with an Intel Core i7 for user development. Optional configurations offer multiple brands and models, including Intel Core i7 or Orin NX, with up to 3 devices. For integrators, the body also offers four 1000M-Base Ethernet ports, four USB3.0 ports and several power outputs.

Technical Specifications

Specifications as published by the manufacturer; confirmed against the datasheet at quotation.

The manufacturer has not published the contents of the Navigation Kit, the contents of the box, the navigation software features, the payload mounting details, the charger specifications, the wireless connectivity or the degrees of freedom; they are confirmed at quotation.

What makes the B2 suited to heavy outdoor work?

Three groups of figures explain it. The first is protection and temperature: an IP67 rating and an operating range of -20℃ ~ 55℃ mean that rain, dust and heat are design conditions rather than reasons to stop. In a tropical or coastal setting, where humidity and sun are constant, those numbers matter as much as speed.

The second is terrain. The robot climbs slopes above 45°, handles continuous stairs of 20~25cm, jumps ditches 0.5~1.2m wide and can leap more than 1.6m. Those are the awkward obstacles of industrial sites: steps between platforms, drainage channels, broken ground and ramps.

The third is stamina under load. Walking without load, the B2 runs for more than 5h and covers more than 20km. Carrying 20kg, it still manages more than 4h and more than 15km. For a patrol or survey shift, that is the difference between finishing the round and returning for a recharge halfway through.

How does the B2 compare with the B2-W?

The sources name two versions, the B2 and the B2-W. The B2-W is the wheeled sibling and has its own page, listed as the Unitree B2-W Wheeled Quadruped Robot, and a kit page, the Unitree B2-W Industry Grade Quadruped Robot Dog with Wheels Basic B2-W Kit with Battery, Navigation Kit. The figures in the table above belong to the B2 described on this page, and the B2-W figures are given on its own page.

The wheeled foot is listed as an option. Teams whose routes include long, smooth corridors or yards may want to ask about it when they request a quotation, while teams whose routes are mostly stairs, thresholds and rough ground will find the legged B2 the more direct fit.

Who is the Unitree B2 with Navigation Kit for?

The first segment is industrial inspection and patrol teams, such as utilities, energy sites, ports and plants, who need a machine that walks the same route repeatedly in heat and rain. The second is integrators and solution builders who want a rugged legged body with several Ethernet, USB and power outputs, plus compute options for their own software. The third is research groups working on navigation, perception and legged locomotion outdoors, who benefit from the Intel Core i7 user-development computer and the optional Orin NX devices.

Security, emergency response and survey organizations also fit the profile, since the load figures leave room for added equipment. Buyers who need only a lighter platform for teaching may prefer a smaller robot from the Standard Quadrupeds category, which is better matched to classrooms and demonstrations.

What is the Unitree B2 with Navigation Kit used for?

1. Industrial inspection: walks plant routes, climbs stairs of 20~25cm and carries sensing equipment between stations.
2. Site patrol: covers more than 20km without load, so a single charge can cover a large perimeter.
3. Equipment carrying: walks under a load above 40kg and stands under 120kg or more for light logistics tasks.
4. Research and development: uses the Intel Core i7 user-development computer and optional Orin NX devices for navigation and perception work.
5. System integration: connects third-party sensors and tools through the Ethernet, USB3.0 and 12V, 24V and 5V ports.
6. Harsh-environment work: operates under IP67 protection in temperatures from -20℃ to 55℃.

Pricing and Availability

Pricing is arranged by quotation, since the configuration, the compute option and the wheeled foot all shape the final package. Delivery, customs and support are arranged together with the quotation, so the buyer sees the whole picture before committing. The Unitree B2 Quadruped Robot with Navigation Kit Package is available on this page.

Frequently Asked Questions

How long can the B2 run on one charge?

Walking without load, it runs more than 5h and covers more than 20km. With a 20kg load, it runs more than 4h and covers more than 15km.

Is the B2 protected against water and dust?

Yes, its ingress protection is IP67. The operating temperature range is -20℃ ~ 55℃.

How much can the B2 carry?

The standing load is 120kg or more and the walking load is above 40kg.

What computing options are available?

The standard configuration has an Intel Core i5 for platform functions and an Intel Core i7 for user development. Optional configurations include Intel Core i7 or Orin NX, up to 3 devices.

Can the B2 climb stairs?

Yes, it climbs continuous stairs of 20~25cm and handles slopes above 45°.

What sensors does the B2 carry?

The sensing set is one 3D LiDAR, two depth cameras and two optical cameras, and it varies with the configuration.

Where can I buy the Unitree B2 Quadruped Robot with Navigation Kit Package and what does it cost?

It is available through this page by quotation. The cost depends on the configuration, so we send a quotation covering the package, delivery, customs and support instead of a fixed figure.

Summary

The B2 with Navigation Kit Package earns its place at the end of the working day, not at the start of the demonstration. It offers more than 5h of unloaded walking, a load of 120kg or more when standing, IP67 protection, and room for the buyer's own computing and sensors. Teams that want a legged machine for demanding routes will find the figures easy to weigh. To start a quotation, this page is the starting point.
