Birkhauser Unitree B2

Unitree B2

Unitree B2 is an advanced industrial walking platform designed to operate in the most demanding conditions. The robot reaches a top speed of about 6 m/s, weighs about 60 kg (including the battery) and combines high dynamic motion with long operating time. Its payload capacity of up to 120 kg in static mode and more than 40 kg when moving makes it ideal for logistics, inspection and rescue tasks. It's a solution built for real-world industrial applications where performance, reliability and durability are key.

Impressive speed of movement

This model is among the fastest industrial four-legged robots in its class - it reaches speeds of up to 6 m/s. Such dynamics allows it to move quickly between work points, respond efficiently to changing conditions and complete tasks over vast areas in less time. At the same time, the B2's design ensures high stability even during dynamic maneuvers, which is crucial in industrial and off-road applications where safety plays a paramount role.

Performance and precision mechanics

High-performance M107 joint modules, generating torque of around 360 N-m, are responsible for smooth yet dynamic movement. This represents a clear leap in performance over earlier designs in this class. Such a large power reserve translates into better stability, more precise motion control and the ability to work with heavy loads. As a result, the robot maintains its balance even on demanding ground and effortlessly performs dynamic maneuvers in difficult operating conditions.

Effective adaptation to diverse terrain

The robot's design has been developed to operate in highly variable and demanding conditions. The device easily navigates slippery and uneven surfaces such as wet floors, stones, debris or steep slopes. It also easily copes with inclines of up to 45° and stairs with step heights of 20 to 25 cm. Such a high level of terrain adaptation allows it to operate effectively in places where classic mobile robots are no longer effective.

Overcoming obstacles and dynamic jumps

One of the key advantages of Unitree B2 is its ability to efficiently overcome obstacles as high as 40 cm. The robot moves stably over platforms, piles of wood or infrastructure elements that challenge classic mobile systems. In addition, it can make jumps of up to 1.6 meters, jump over gaps of 0.5 to 1.2 meters, and jump from heights of up to 1 meter without risk of damage. Such capabilities significantly expand its operational potential in demanding terrain and during rescue operations.

High carrying capacity and long-lasting operation

The device is distinguished by its impressive lifting capacity and high endurance during long-term operation. In static mode, it is able to safely hold a load of up to 120 kg, and when moving it can transport weights of up to 40 kg. In continuous walking with a load of 20 kg, the operating time is about 4 hours, which can cover a distance of up to 15 km. Without an additional load, the Unitree B2 can operate for up to about 5 hours, reaching a range of 20 km.

Precise orientation in space

The use of a 32-beam automotive-grade LiDAR sensor, a depth camera and a high-resolution optical camera allows for accurate recognition of the surroundings and confident navigation in complex environments. Such a sensory system supports stable navigation and ensures efficient execution of inspection tasks, space mapping and work in areas with limited visibility and complex terrain.

Stable and long-lasting power supply

A large-capacity 45 Ah (2250 Wh) 58-volt battery provides an operating time of up to about 4-6 hours, allowing the company to carry out long and demanding missions without frequent interruptions. Optional autonomous charging systems are also available to automatically renew energy and better adapt the robot to more complex operational scenarios. In addition, the plug-in design significantly speeds up battery replacement, minimizing downtime and allowing the device to be quickly ready for the next task.

Adaptable for harsh environments

The robot's design meets IP67 requirements, providing effective protection against dust and water. The device can operate in a wide temperature range (from -20°C to 55°C) - it is not intimidated by variable and adverse weather conditions. Such parameters allow reliable use both inside industrial facilities and in the open field - regardless of season or weather.

Professional field and industrial applications

The Unitree B2 robot is ideal for energy infrastructure inspections, rescue operations, field patrols and logistical tasks. The combination of high speed, high carrying capacity, advanced perception systems and long operating time makes it an indispensable support in situations where operational efficiency, reliability and operational safety are crucial.
