Unitree Go2-W

What Separates Go2-W from Go2?

Go2-W is the Go2 platform carrying wheeled feet. A 70 × 43 × 50 cm body weighs about 18 kg with the battery. The payoff of the wheeled architecture again shows up in range and endurance: 1.5–3 hours of operation from a 15,000 mAh long-range battery. Speed range is 0–2.5 m/s, maximum climbing incline 35°, and maximum obstacle height 70 cm. It uses 16 aluminium knee joint motors; peak torque of the largest motor is about 45 N·m.

Payload and Its Limits

Payload is about 8 kg with a peak of ~12 kg. Against an 18 kg body weight this is a payload-to-weight ratio of roughly 0.44. In practice it is enough to carry a single sensor load — a thermal camera, gas detector or small compute module; stacking multiple pieces of equipment is not this class's job. The 45 N·m joint torque is sized to the same scale: the near eightfold gap to the B2's 360 N·m shows directly that the two robots do not do the same work.

Sensing and Connectivity

• Super-wide-angle 3D LiDAR and HD wide-angle camera.
• 8-core high-performance CPU.
• WiFi 6, 4G and Bluetooth — 4G makes remote connectivity possible on sites without wireless coverage.
• App support, handheld controller, voice commands and OTA updates.
• Charging: fast charge (33.6 V 9 A); operating voltage 33.6 V.

Engineering Assessment

Go2-W provides entry-level access to the wheeled-legged architecture: the same capability family without stepping up to the AS2-W's scale and budget. Its right job is patrol with a light sensor payload in indoor and semi-outdoor space, plus education and development. Its limits are explicit — 8 kg payload, 35° incline and a 1.5–3 hour operating window. If long-distance outdoor inspection is needed the answer is AS2-W; if heavy equipment must be carried, the B2. It ships with a 12-month warranty.
