Powerful Quadruped with advanced sensors
The B2 is the fastest industrial‑grade quadruped robot, reaching speeds over 6 m/s, with high‑torque joints and exceptional load capacity—continuously carrying more than 40 kg for over four hours and exceeding five hours of endurance unloaded. Its robust design handles slippery surfaces, stairs, 40 cm obstacles and slopes steeper than 45°, while its modular wheel‑leg configuration and quick‑swappable battery (with optional autonomous charging) make it versatile for demanding industrial environments.

Unitree B2 variations
Unitree B2 is a heavy‑duty industrial robot built for extreme environments. It blends high‑speed mobility with rugged terrain capability, providing stability on stairs, slopes and uneven ground. High‑torque joints and superior obstacle‑crossing broaden its uses, while wheeled‑leg options and plug‑in batteries support extended missions. B2 is suited to inspection, power maintenance, rescue and other demanding applications.
B2
This flagship configuration is the fastest industrial‑grade quadruped on the market, running at more than 6 m/s unitree.com unitree.com . Its high‑torque joints deliver around 360 N·m unitree.com , enabling it to carry over 40 kg continuously for more than four hours (covering roughly 15 km) or walk for over five hours without a load unitree.com unitree.com . B2 can cross obstacles up to 40 cm high and tackle slopes steeper than 45° unitree.com unitree.com while maintaining up to 120 kg static load capacity unitree.com . Choose this model when dynamic speed, robust climbing and long endurance are critical in confined or uneven terrains.
B2-W
Designed for extended range and mixed‑terrain efficiency, the B2‑W replaces the standard feet with wheel modules, allowing on‑the‑fly conversion between driving and walking. It travels up to 15 km/h and can cover approximately 25 km while carrying a 40 kg payload, or about 30 km when unloaded unitree.com unitree.com . The robot weighs around 85 kg with battery and houses a battery pack exceeding 2 kWh for long‑duration missions unitree.com . Each wheel provides 40 N·m of torque and spins up to 50 rad/s unitree.com unitree.com , enabling smooth travel on roads and hard surfaces. B2‑W maintains the same 120 kg static load rating and can walk on steps up to 20–25 cm, climb 40 cm obstacles and handle slopes greater than 45° unitree.com . It also operates in temperatures from −20 °C to 55 °C and is rated IP67 for dust and water resistance.
Solutions
With the Nortemsy Robotics Platform these quadruped robots move beyond being demonstrations or experimental devices: our system connects to the units in real time, automates supervisory tasks and allows the Go2, A2 or B2 to patrol, carry loads or inspect equipment autonomously.
Through cloud‑based fleet management, integrated sensors and advanced mission planning, the robots become reliable “team members” who can support human staff around the clock in a wide range of environments and roles. Below we present the most common use cases where quadruped robots have proven to work efficiently with Nortemsy solutions.
