Task and control

Form: Quadruped
Use: Companion, Education, Research
User programming: Yes
Phone app: Yes
Intended use: Air and Pro provide remote-control and demonstration functions; EDU is the maker's configuration for robotics research and secondary development.
Movement: Air 0–2.5 m/s, Pro 0–3.5 m/s and X/EDU 0–3.7 m/s, with an approximately 5 m/s maximum claim for X/EDU. Published climbing angles are 30° for Air and 40° for the other configurations; performance depends on terrain and configuration.
Autonomy: LiDAR-based detection and avoidance are listed across the range. ISS 2.0 side-following is included on Pro, X and EDU, rather than Air. Demonstrations and AI descriptions do not establish general autonomous household work.
User programming: The maker lists graphical programming across the range, so basic app programming is distinct from full secondary development. Its comparison table lists none for Air/Pro, partial access for X and full access for EDU; select the development configuration required for the task.
Remote control: App control; handheld controller optional on Air/Pro and included with X/EDU in the maker's comparison. Store bundles also offer Air/Pro with a controller.
Regional availability: The official global store accepts orders for Air, Pro and X; its selected product variants are available and its delivery note says shipment within one month. EDU requires a sales quotation. Freight, import clearance and destination rules apply; this is not a statement of immediate UK warehouse stock. Checked October 2026.
Release details: Unitree's dated press release confirms the announcement on 12 July 2023. The first retail delivery date is not established by the sources used; the store listing's creation date is not treated as first sale.

Hardware

Degrees of freedom: 12
Height: 400 mm
Width: 310 mm
Depth: 700 mm
Robot weight: 15 kg
Camera: Yes
Wi-Fi: Yes
Bluetooth: Yes
Processing: Eight-core high-performance CPU listed for Pro, X and EDU; the maker's table does not list that computing specification for Air. EDU offers additional compute modules, including Orin configurations.
Sensors: Ultra-wide-angle 4D LiDAR and HD wide-angle camera across the range; foot-end force sensors and a depth camera are listed for EDU.
Camera: Front HD wide-angle camera; real-time image transmission through the app. EDU adds a depth camera.
Audio: Voice function is listed for Pro, X and EDU; the maker marks it absent for Air.
Actuators: Twelve aluminium knee-joint motor assemblies; approximately 45 N·m maximum largest-joint torque is listed for Pro/X/EDU. This is not the torque of every joint or a combined total.
Payload: Air approximately 7 kg, maximum approximately 10 kg; Pro approximately 8 kg, maximum approximately 10 kg; X/EDU approximately 8 kg, maximum approximately 12 kg. Retain the maker's distinction between normal and maximum loads.
Connections: Dual-band Wi-Fi 6 and Bluetooth 5.2/4.2/2.1; 4G module with GPS on Pro/X/EDU rather than Air.
Size and weight: Standing length × width × height 70 × 31 × 40 cm; crouching 76 × 31 × 20 cm. Approximately 15 kg with battery; aluminium alloy and high-strength engineering plastic.
Durability: No ingress-protection rating is published on the exact Go2 specification page used.

Battery

Battery life (maker's claim): About 1–2 hours / About 2–4 hours
Battery capacity: 8,000–15,000 mAh
Battery: Standard battery 8,000 mAh on Air/Pro/X; long-endurance 15,000 mAh battery listed for EDU. Battery removable. Operating voltage 28–33.6 V.
Charging: Air/Pro/X standard 33.6 V 3.5 A charger; EDU 33.6 V 9 A fast charger.
Runtime conditions: Maker claims about 1–2 hours with the standard battery and about 2–4 hours with the long-endurance battery. The headline longer runtime is not standard across configurations; actual runtime varies by conditions.
Dock: Charging-pile compatibility is listed for X and EDU, absent for Air/Pro. Compatibility alone does not establish an autonomous return-to-dock function or an included dock.

Configurations
