Industrial Autonomous Quadruped Robot
Unitree B2 Industrial Quadruped Robot with Navigation Kit
The Unitree B2 is a heavy-duty industrial quadruped robot designed for inspection, autonomous patrol, emergency response, infrastructure monitoring, robotics integration and demanding all-terrain field operations. This listing adds a Navigation Kit to the B2 platform, creating a configuration intended for autonomous mapping, localization, obstacle avoidance and repeatable mission execution.
For buyers searching for a Unitree B2 for sale, the main reason to choose this configuration over a standard B2 is not simply an additional LiDAR sensor. A complete navigation package can add dedicated environmental perception, navigation compute and autonomy software for SLAM, route planning and unmanned patrol workflows.
AI Robot Supplier currently lists this B2 Navigation Kit configuration at $60,000. Because current international B2 packages vary substantially in LiDAR, compute, controllers, accessories, software, freight and support, buyers should confirm the exact supplied Navigation Kit before comparing prices.

Product overview
What Is the Unitree B2?
The Unitree B2 is a professional industrial robot dog built for applications where payload, endurance, terrain capability and development flexibility matter more than compact size or consumer-oriented interaction.
The robot measures approximately 1098 × 450 × 645 mm while standing and approximately 880 × 460 × 330 mm while prone. Unitree lists total weight at approximately 60 kg with its battery installed.
Twelve powered joints generate up to approximately 360 N·m maximum joint torque, enabling operation across stairs, slopes, debris and uneven terrain. Unitree publishes a continuous walking payload greater than 40 kg and a standing-load reference of at least 120 kg.
B2 is therefore better compared with industrial inspection robots than lightweight robot dogs such as
Unitree Go2 Pro.
Projects requiring a lighter professional quadruped should also compare
Unitree A2 Pro.

Real-world performance context
Unitree B2 Speed, Payload and Terrain Performance
Speed: More Than 6 m/s
Unitree advertises performance above 6 m/s, but explicitly states that this result is achieved in special configurations and practical use includes a safety speed limit. Do not plan normal loaded inspection missions around sustained maximum-speed operation.
Walking Payload: More Than 40 kg
The continuous walking-load figure is the more useful payload specification for industrial projects. Payload, speed, slopes and battery runtime interact, so actual mission design should use conservative margins.
Standing Load: At Least 120 kg
The 120 kg figure is a standing-load reference. It does not mean B2 should routinely carry a 120 kg payload while walking.
Why Payload Numbers Online Can Be Misleading
Some reseller pages headline “120 kg payload” without distinguishing static and walking conditions. Unitree’s own specification separates them: ≥120 kg standing load and >40 kg continuous walking load.
Battery & endurance
Unitree B2 Battery Life, Range and Charging
45 Ah / 2,250 Wh Battery
B2 uses a high-capacity removable battery designed around multi-hour industrial operation.
5+ Hours Unloaded
Unitree publishes more than five hours of unloaded continuous walking and more than 20 km of travel under reference conditions.
4+ Hours With 20 kg
With a 20 kg load, the manufacturer publishes more than four hours of continuous walking and more than 15 km.
Quick-Change and Autonomous Charging Options
Unitree supports quick battery replacement and also describes optional autonomous charging solutions for B2 deployments.
The main official B2 page does not provide one fixed charging-time figure. Some current reseller specifications quote approximately 2.5 hours, but this should be treated as a distributor reference and verified against the exact charger supplied.
For additional field endurance, compare the
Unitree B2 Standard Battery.

Buyer limitations
Important Unitree B2 Limitations Before Buying
-
120 kg is not the normal walking payload:
Unitree separates ≥120 kg standing load from >40 kg continuous walking load. -
>6 m/s is not a normal industrial mission speed:
Unitree states that the highest speed is achieved in special configurations and practical operation uses safety limits. -
Navigation requires commissioning:
LiDAR and autonomy software do not eliminate the need to map the site, configure routes, establish safety rules and validate performance. -
Autonomous patrol is application-dependent:
mission reliability depends on sensor placement, software, route design, environmental change and network architecture. -
Battery endurance varies:
payload, stairs, terrain, speed, temperature, compute and mounted accessories affect real runtime. -
The Navigation Kit is configuration-sensitive:
confirm the exact sensor, compute and software stack instead of assuming all sellers use the same package. -
Charging time should be confirmed:
the main Unitree B2 page does not publish one fixed full-charge time. -
High-performance quadrupeds require safety controls:
professional operation should follow Unitree procedures and local workplace requirements.
Buyer fit
Who Should Buy Unitree B2?
Choose B2 Navigation Kit
Best suited to industrial or research teams that need heavy payload, all-terrain mobility and an integrated foundation for autonomous mapping and patrol.
Choose Standard B2
A standard B2 can make more sense when your team already has its own navigation, sensing and autonomy stack or mainly needs teleoperated heavy-duty mobility.
Choose B2-W
Choose the wheeled variant when long routes, smooth-floor efficiency and rolling speed matter more than remaining purely legged.
Choose A2 Pro
A2 Pro is more appropriate when a lighter 25 kg payload-class robot meets the mission requirements and B2’s mass and cost are unnecessary.
Choose Go2 Pro
Go2 Pro is far easier to transport and much less expensive when the requirement is demonstration, lighter sensing or compact experimentation rather than industrial payload.
Add a Z1 Arm
A manipulation project may require a compatible Unitree arm, gripper, mounting solution and additional integration rather than the navigation package alone.
