Unitree B2 Review: Specs and Uses of the 60 kg Industrial Quadruped Robot
Updated: 7 days ago
The Unitree B2 is an industrial quadruped robot that weighs about 60 kg, carries more than 40 kg while walking and is protected to IP67. The manufacturer does not publish a firm price. This review covers its specifications, design, computing and uses.
Quick Verdict
The B2 is Unitree's working dog, four times the weight of the Go2 and built for outdoor industrial use. It carries a continuous walking load above 40 kg, runs for 4 to 6 hours on a 2250 Wh battery, climbs stairs with 20 to 25 cm steps and works from -20 °C to 55 °C with IP67 sealing. Joints of about 360 N·m give it large reserves, and the maker quotes a top speed above 6 m/s in special configurations. It is intended for inspection, emergency response and carrying equipment. Price is given on request.

Design and Build Quality
The B2 is built for conditions that would stop a lighter robot. IP67 sealing protects it against dust and immersion, and the temperature range covers most outdoor sites. The large battery can be swapped quickly, and an automatic charging station is available for unattended operation. Payload interfaces are generous: Ethernet, USB and several supply voltages are provided for cameras, gas sensors or manipulators. The maker notes that a speed limit applies in practice for safety.
Software and Development
Computing
The robot carries separate computers for its own functions and for user development, with up to three units possible.
Sensors
The sensor set depends on the configuration ordered.
Unitree B2 Uses
The B2 is aimed at inspection, emergency response and transport on difficult ground.
Industrial and Power Inspection
