The Unitree B2 is an industrial-grade quadruped robot measuring approximately 1,098 by 450 by 645 mm standing and weighing approximately 60 kg with battery. It reaches over 6 m/s top speed with 360 N·m maximum joint torque (a 170 percent increase over previous generation), jumping over 1.6 m. Standing load exceeds 120 kg with continuous walking load over 40 kg. It climbs over 40 cm obstacles and over 45-degree slopes, with 20 to 25 cm continuous stair climbing and 0.5 to 1.2 m ditch jumping. A 45 Ah (2,250 Wh) 58 V battery provides 4 to 6 hours runtime, with over 5 hours unloaded walking exceeding 20 km and over 4 hours with 20 kg load exceeding 15 km. Rated IP67 with -20 to 55 degrees C operating range. An innovative structural design enables switching between legged and wheeled forms (optional). The plug-in battery supports quick change and autonomous charging (optional). Standard Intel Core i5/i7 processors with optional Orin NX (up to 3 devices). Sensors include 3D LiDAR, 2 depth cameras, and 2 optical cameras. External interfaces include 4 Gigabit Ethernet, 4 USB 3.0, and multiple power outputs. Targets industrial inspection, emergency rescue, and power inspection.
