Unitree B2 Industry Grade Quadruped Robot Dog Basic B2 Kit with Battery, Navigation Kit

Most machines are rated by what they weigh, but a working quadruped is better judged by what it can hold up. The Unitree B2 Industry Grade Quadruped Robot Dog Basic B2 Kit with Battery, Navigation Kit weighs around 60kg with its battery fitted, yet it bears a standing load of at least 120kg and keeps walking with more than 40kg on its back. A frame that supports twice its own mass shapes everything else about the robot: its joints, its battery, how it is deployed and the work it is bought for. This kit pairs the robot with its battery and a navigation kit, so that it arrives as a platform to plan operations around rather than a bare chassis.

Robots Middle East supplies this kit to organisations across the Middle East, from industrial operators and utilities to universities, laboratories and system integrators. Robots Middle East prepares the quotation for your configuration, arranges delivery to your site and provides support after handover, so that one partner remains accountable from the first enquiry through to the robot's working life in the field.

Background

Unitree Robotics and its industrial line

Unitree Robotics is a Chinese manufacturer that became widely known for compact legged robots before extending its range into larger industrial platforms and humanoids. Its quadrupeds run from education and research models to machines intended for inspection and field duty, and the B2 sits at the heavy, industrial end of that portfolio. It is conceived for sites where a robot must carry real equipment for hours, in heat or cold, rather than demonstrate agility for a few minutes on a smooth floor.

Torque, endurance and a swappable power supply

The B2's capability rests on high-torque joints, with a maximum joint torque of about 360N.m, and on a 58V battery with a capacity of 45Ah (2250Wh). The battery supports quick change, so a team can swap packs and keep a robot working across shifts, and an autonomous charging solution is available as an option. The structure is also designed to switch between legged and wheeled forms as an option, and the software receives continuous OTA upgrades and updates, so the platform can gain capability after it has been deployed.

Technical Specifications

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

The manufacturer has not published the remote controller specifications, the charging time, the charger specifications, the contents of the navigation kit or the software and SDK details on its product page; these are confirmed at quotation.

What does the navigation kit add to the Unitree B2?

Autonomous movement through a plant or a campus depends on two things: knowing what surrounds the robot and having the computing power to act on it. In its standard configuration the B2 carries a 3D LiDAR, two depth cameras and two optical cameras, with the exact sensor set varying by configuration. The LiDAR gives the robot a three-dimensional picture of the space around it, the depth cameras help it judge steps and obstacles close to its feet, and the optical cameras supply the images that inspection and monitoring tasks depend upon.

Computing is divided deliberately. An Intel Core i5 handles platform functions, while an Intel Core i7 is reserved for user development, so that your own mapping, recognition or mission software can run without competing with the robot's core control. The navigation kit is supplied with the robot to build on this foundation, giving route-based work a sensor and computing base from the day the robot arrives.

How far can the Unitree B2 travel on one battery?

Endurance is where the heavy battery earns its place. Battery life is 4-6h. Walking without load, the B2 runs for more than 5h and covers more than 20km; with a 20kg load it still walks for more than 4h and covers more than 15km. For a patrol or inspection round this means a robot can complete long routes, return, receive a fresh pack through the quick-change design and set out again, rather than waiting out a charging cycle in the middle of a shift.

Speed is managed with the same practicality. The headline running speed is realised in special configurations, and in practice a speed limit applies for safety. For industrial work this is the sensible priority: a robot carrying sensors near people and equipment is valued for steady, repeatable movement, and its terrain figures — obstacles of up to 40cm, continuous stairs of 20~25cm and ditches of 0.5~1.2m — matter far more on a working site than outright pace.

Who is the Unitree B2 for?

The B2 suits organisations whose routes include stairs, gratings, kerbs and uneven ground, and whose missions demand more payload than a light quadruped can carry. Oil, gas and petrochemical operators, power and water utilities, and large logistics or manufacturing sites can use it to carry inspection sensors on repeatable rounds. Its operating range of -20℃ ~ 55℃ makes it relevant to outdoor installations exposed to summer heat as well as to cold-storage and high-altitude environments.

Universities, research institutes and robotics integrators form a second audience. The dedicated Intel Core i7 for user development, continuous OTA updates and a payload margin generous enough for additional instruments make the B2 a capable base for work on autonomy, perception and field robotics. Security and public-safety teams, meanwhile, may value a platform that can patrol perimeters and enter buildings where a wheeled vehicle would stop at the first flight of steps.

Buyers whose routes run mostly over paved roads, warehouse floors or long flat stretches may wish to compare the wheeled sibling, the Unitree B2-W Industry Grade Quadruped Robot Dog with Wheels Basic B2-W Kit with Battery, Navigation Kit, before deciding. The complete range of related configurations can be viewed in the Unitree B2 category.

What is the Unitree B2 used for?

1. Industrial inspection rounds: carrying cameras and sensors along fixed routes through plants, substations and pipelines.
2. Energy and utility sites: reaching gauges, valves and equipment rooms behind stairs and raised walkways.
3. Security patrols: repeating perimeter and building routes with a consistent, recorded pattern.
4. Load carrying on difficult ground: moving tools, instruments or supplies where carts and wheeled robots cannot pass.
5. Research and development: serving as a heavy-duty platform for autonomy, perception and navigation software.
6. Emergency response and survey: entering hazardous or unstable areas so that personnel can assess them from a distance.

Summary

The B2 is defined by a simple but demanding ratio: a machine of around 60kg that stands under at least 120kg and walks for hours with equipment on its back. High-torque joints, a large quick-change battery, a layered sensor suite and separate computing for your own development turn that strength into dependable work on stairs, gratings and rough ground, from the heat of an outdoor plant to the cold of a storage facility. For teams that need a quadruped to carry its share of the load, and a regional partner to quote, deliver and support it, this page is the starting point.
