At CES 2025, Unitree shows its wheeled-legged quadrupeds Go2-W and B2-W. The industrial B2-W supports 120 kg standing, drives at 15 km/h and covers up to 25 km with 40 kg.

### What changes At CES in Las Vegas in January 2025, Unitree showcased two wheeled-legged quadrupeds: the Go2-W, the wheeled version of its consumer Go2 robot dog, and the B2-W, the industrial variant of its B2. Motorized wheels at the end of the legs let them drive fast on flat ground and walk over obstacles and stairs. ### Specifications (B2-W, official spec sheet) - Weight about 85 kg including battery. - Payload: 120 kg standing, over 40 kg walking. - Top speed 15 km/h; about 25 km range with 40 kg and about 30 km unloaded; battery over 2 kWh. - Climbs and descends 40 cm steps, slopes over 45°. - IP67 protection; operates from -20 to 55 °C; Intel Core i5 compute, optional i7 or NVIDIA Orin NX. ### Why it matters Unitree popularized wheeled-legged locomotion, later taken up by the As2-W, DEEP Robotics (Lynx) and RIVR. The format meets a concrete need: covering long distances on industrial sites without losing the ability to climb stairs. ### Key takeaways Date set to January 7, 2025, the opening day of CES. The B2-W was announced alongside the B2 (late 2023): this entry marks its public CES showcase, not its first availability, whose exact date remains uncertain.
