The Go2-W is the wheeled-legged version of Unitree's best-known small quadruped: seven-inch pneumatic tyres on the ends of the legs, 70 x 43 x 50 cm standing, about 18 kg with the battery. Sixteen aluminium-knee joint motors put out around 45 N·m, giving a payload of roughly 8 kg and up to 12 kg at maximum, with 2.5 m/s top speed, a 35-degree climb angle and obstacles under 70 cm. A 15000 mAh, 33.6 V pack runs it for one and a half to three hours and fast-charges at 9 A. Sensing is a super-wide-angle 3D lidar and an HD wide-angle camera on an eight-core processor — the same perception stack as the legged Go2, which keeps existing SDK work portable between the two.
