UNITREE B2-W · FAQ
Questions, answered.
Clear answers about B2-W dimensions, range, payload, mobility, operating limits, and configuration options for customers in Canada.
What is the Unitree B2-W?
The Unitree B2-W is a wheeled quadruped robot platform. Its wheel-leg design combines powered wheels with articulated legs. Available functions and hardware depend on the selected configuration.
What are the dimensions and weight of the Unitree B2-W?
The standing dimensions are 1098 mm × 550 mm × 758 mm. In the prone position, the dimensions are approximately 950 mm × 550 mm × 450 mm. Total weight is approximately 85 kg, including the battery.
What is the maximum speed of the Unitree B2-W?
The listed maximum speed is 15 km/h [1]. This figure is achieved in a special configuration. In actual operation, speed limits are applied for safety.
How far can the Unitree B2-W travel?
Maximum range is 25 km with a 40 kg load [2]. Maximum no-load range is 30 km. The referenced loaded-range figure is achieved in a special configuration, and actual range may vary by application and configuration.
How much load can the Unitree B2-W support?
The maximum standing load is 120 kg, while the walking load is greater than 40 kg. These ratings apply to different operating conditions and should not be treated as the same payload specification.
What are the B2-W battery specifications?
The supplied specification lists a battery capacity greater than 2 kWh and a voltage of 58 V. Battery configuration and real-world performance should be confirmed for the selected product configuration.
What are the wheel-system specifications?
Each wheel has a diameter of 225 mm. The listed maximum wheel speed is 50 rad/s, and the listed maximum wheel torque is 40 N·m.
Can the Unitree B2-W climb stairs and slopes?
The B2-W is specified for continuous stair climbing on 20–25 cm steps. It can climb up and down 40 cm steps in the forward direction, and its listed climbing angle is greater than 45°.
What operating conditions is the Unitree B2-W rated for?
The listed operating temperature range is −20°C to 55°C, and the ingress protection rating is IP67. Suitability for a specific environment should be evaluated against the actual configuration and operating procedure.
Which computing configurations are available?
The standard control and perception configuration lists Intel Core i5 for platform functions and Intel Core i7 for user development. The optional configuration lists Intel Core i7 and Jetson Orin NX, with up to 3 devices.
Does every B2-W function work out of the box?
Some functions require manual operation or secondary development and may vary between configurations. Parameters may also differ across application scenarios, so the final specification should be confirmed against the actual product configuration.
The B2-W is a civilian robot. Users should not make dangerous modifications or operate the robot in a hazardous manner.
