Unitree B2-W Review: Specs and Uses of the Industrial Wheeled Quadruped Robot
Updated: 7 days ago
The Unitree B2-W is the wheeled version of Unitree's B2 industrial quadruped, a robot of about 85 kg that rolls and walks. Unitree does not list a price on the product page. This review covers its specifications, design and uses.
Quick Verdict
The B2-W is built for distance and load. On wheels of 225 mm it reaches 15 km/h and covers about 30 km on a charge without load, or 25 km carrying 40 kg, figures that walking robots cannot approach. It still climbs stairs with 20 to 25 cm steps and slopes of more than 45 degrees, and it is sealed to IP67 for work from -20 to 55 °C. Unitree notes that the top figures apply to special configurations and that speed is limited in practice for safety.
