- Form
- Quadruped
- Use
- Education, Research, Inspection
- User programming
- No / Yes
- Phone app
- Yes
- Intended use
- Education, research and inspection applications; select the X/EDU variants for the maker's supported secondary-development interfaces. Air/Pro are not equivalent open development platforms.
- Movement
- Air 0–3.0 m/s; Pro/X/EDU 0–3.7 m/s, with approximately 5 m/s maximum claimed for X/EDU. Published slope capability is about 30° for Air or 40° for the others; stair heights 20 cm for Air or 25 cm for the others. These are maker laboratory figures, not independent terrain tests.
- Autonomy
- ISS 3.0 side-following is listed for Pro/X/EDU, absent for Air. The maker warns that some shown examples are still under development/testing. General application descriptions do not prove unattended inspection or autonomous household work as delivered.
- User programming
- Secondary development is explicitly unsupported on Air and Pro, supported on X and EDU. UniStore platform support is listed across configurations; access to motion routines differs from developer joint/sensor interfaces.
- Remote control
- Controller optional on Air and included with Pro/X/EDU. Maker As2 app available.
- Regional availability
- The official global store accepts orders for As2 Air and Pro; EDU is a contact-sales option. X appears in the maker's specification table but is not a selectable public-store configuration in the inventory checked. Local delivery/import conditions require confirmation; current range presence does not guarantee immediate UK stock. Checked October 2026.
- Release details
- Unitree's own introduction video is dated 24 February 2026. The first retail delivery date is not established; the April 2026 store listing timestamp is not treated as first sale.

- Processing
- Eight-core high-performance CPU across configurations. EDU can add optional high-computing-power modules, including Orin NX configurations.
- Sensors
- Air uses Unitree L2 ultra-wide-angle LiDAR; Pro/X/EDU use industrial-grade 64–128-line LiDAR. HD camera and dual joint encoders across the range.
- Camera
- HD camera listed for all configurations; no exact image-resolution figure is published in the table used.
- Audio
- Microphone and speaker across configurations.
- Actuators
- Twelve joint motors, industrial crossed-roller bearings and local air cooling. Maximum largest-joint torque about 65 N·m for Air, 75 N·m for Pro or 95 N·m for X/EDU; the overview's 95 N·m does not apply to the whole range.
- Payload
- Continuous-walking load approximately 10 kg Air, 13 kg Pro or 15 kg X/EDU. Maximum standing load approximately 45/55/65/65 kg respectively. A stationary load is not a walking payload.
- Connections
- Wi-Fi 6, Bluetooth 5.2, gigabit Ethernet, SBUS and battery-power output. Pro/X/EDU also list GPS and 4G, disabled by default and enabled with user authorisation; Air does not. Regional functionality restrictions may apply.
- Size and weight
- Standing length × width × height 720 × 378 × 457 mm; prone 776 × 378 × 233 mm. Approximately 20 kg with battery. Aluminium alloy and high-strength engineering plastic.
- Durability
- IP54 is published for Pro/X/EDU, not Air. Operating temperature −20 to 50°C for Air/Pro or −20 to 55°C for X/EDU. IP54 is not an immersion rating.
Battery
- Battery life (maker's claim)
- About 2 hours of unloaded continuous walking / About 4 hours of unloaded continuous walking
- Battery capacity
- 8,000–15,000 mAh
- Battery
- Air supplied with standard 8,000 mAh battery; Pro/X/EDU with long-range 15,000 mAh battery. The overview gives 648 Wh for the larger pack. Supply voltage 36–50.4 V.
- Charging
- Air standard 50.4 V 4 A charger; Pro/X/EDU 50.4 V 7.4 A fast charger. No exact full-charge duration is published in the comparison table used.
- Runtime conditions
- Air about 2 hours/10 km unloaded, or more than 1.5 hours/about 7 km carrying 10 kg. Pro about 4 hours/20 km unloaded, or more than 2.5 hours/about 13 km carrying 13 kg. X/EDU about 4 hours/20 km unloaded, or more than 2.5 hours/about 13 km carrying 15 kg. Maker laboratory claims; the overview's longest figures are not standard Air performance.
- Dock
- Charging dock listed for EDU, absent for Air/Pro/X. Dock presence is not proof of autonomous return-to-charge behaviour.
