Unitree Go2-W

A wheeled-leg version of Unitree's Go2, with a driven wheel mounted at the end of each leg.

Go2-W is a wheeled-leg robot Unitree Robotics built on the Go2 platform: each leg ends in a 7-inch pneumatic wheel with a hub motor, so it rolls on its wheels on flat ground and lifts its legs to climb steps or slopes. Published specs: about 70 × 43 × 50 cm, about 18 kg including the battery, a normal payload of about 8 kg (up to about 12 kg at the limit), a speed of 0–2.5 m/s, a maximum climbing grade of 35°, roughly 1.5–3 hours of runtime, and an onboard 3D lidar and HD camera. Wheeled legs balance speed, energy use, and the ability to cross obstacles, but coordinating the wheels and legs is harder, and this is usually trained with reinforcement learning in simulation. It belongs to the same wheeled-leg product family as the larger B2-W.
