Key Numbers
The most important specifications distilled into a single view.
Engineered for Intelligent Mobility
The Unitree R1 brings together advanced mechanical design, integrated AI, and open developer interfaces in a lightweight, ready-to-deploy humanoid platform.
Agile Mobility Across Complex Environments
With up to 26 degrees of freedom — including a 2-DOF waist, 2-DOF articulated head, 5-DOF arms, and 6-DOF legs per side — the Unitree R1 adapts its posture and movement to real-world terrain. The compact 1,230 mm frame and ~29 kg body weight make it one of the lightest full-featured humanoids available, while crossed roller bearings and PMSM joint motors deliver fast, precise, and thermally efficient actuation.
- 26 total degrees of freedom with waist and head articulation
- Knee range: -10° to +139° for deep squat and stair capability
- Hip Y-axis: ±157° — wide lateral leg sweep
- Low-inertia PMSM motors for rapid response and heat control
Multimodal AI — Voice, Vision, and Action
The Unitree R1 integrates a Large Multimodal Model (LMM) that processes both voice commands and visual input simultaneously. A 4-microphone array captures directional audio, while the binocular camera provides stereo depth perception. The 8-core processor and built-in speaker complete the interaction loop — enabling the robot to listen, see, interpret, and respond in real time without external compute modules.
- Large Multimodal Model for natural language and vision
- 4-mic array for directional voice capture
- Binocular camera with stereo depth perception
- 8-core processor with built-in speaker output
Open Platform for Developers and Researchers
The Unitree R1 offers fully open joint and sensor control interfaces, and supports mainstream simulation platforms — enabling algorithm development that transfers directly to the physical robot. Continuous OTA updates keep the software stack current without manual intervention. The quick-release smart battery system simplifies field operation, and the manual controller provides direct human oversight at any time.
- Open control interfaces for all joints and sensors
- Compatible with mainstream simulation environments
- Continuous OTA software upgrades included
- Quick-release smart battery with charger and controller
What Sets the R1 Apart
26-DOF Full-Body Articulation
Head, waist, arms, and legs all move independently. The 2-DOF waist and 2-DOF articulated head dramatically expand environmental perception and task reach.
Ultra-Lightweight ~29 kg
At approximately 29 kg with battery, the R1 is designed to operate safely in spaces built for humans — no reinforced floors or special infrastructure needed.
Large Multimodal Model (LMM)
Processes voice and visual input simultaneously. Natural language commands are interpreted alongside real-time binocular camera data for contextual responses.
Binocular Camera & 4-Mic Array
Stereo depth perception from dual cameras combined with a 4-microphone directional array gives the R1 rich environmental awareness from the front and above.
Continuous OTA Updates
Over-the-air software upgrades are delivered wirelessly and automatically. The R1 grows more capable over time without requiring physical service or manual patching.
Wi-Fi 6 + Bluetooth 5.2
Latest-generation wireless connectivity ensures fast, reliable communication with apps, control systems, and cloud services at home or in the field.
PMSM Joints with Precision Bearings
Low-inertia, high-speed internal rotor permanent magnet synchronous motors with crossed roller bearings deliver responsive, thermally efficient joint actuation.
Open Developer Interface
All joint and sensor interfaces are fully exposed. Compatible with leading simulation platforms, letting researchers and developers test algorithms before physical deployment.
Quick-Release Smart Battery
The smart lithium battery is hot-swappable for extended continuous operation. Each charge delivers approximately 1 hour of runtime under typical conditions.
