Unitree R1-D
The Unitree R1-D is a dual-arm humanoid robot platform launched by Unitree Robotics in April 2026. Starting at $4,290, the R1-D is configurable with 5-DOF (R1-A5) or 7-DOF (R1-A7) robotic arms and offers 15-31 total degrees of freedom. Weighing approximately 11-13 kg (fixed base) or 30-32 kg (mobile wheeled base), the platform is certified for industrial precision assembly tasks with ±0.1mm end-effector accuracy. It features an 8-core high-performance CPU in the body and an 8-core CPU + 10 TOPS AI processor in the head module. Optional NVIDIA Jetson Orin module provides up to 40-100 TOPS AI performance. Environmental perception and voice interaction via RGBD binocular camera (544x448@10Hz), 4-array microphone and dual speakers. A powerful manipulation platform for research labs, industrial automation and educational institutions with fixed base (R1-A5/A7) or mobile wheeled base (R1-A5-D/R1-A7-D) options.

Unitree R1-D — Dual-Arm Manipulation Platform Technical Analysis
Mechanical Design and Kinematic Structure
- R1-D is a dual-arm humanoid robot platform offered in 5-DOF (R1-A5) or 7-DOF (R1-A7) configurations. Each arm has the same DoF value and provides a symmetric working envelope.
- The waist joint provides Yaw ±115° and Pitch ±36° movement range for a wide working volume. The neck joint has the same range and optimizes head module environmental perception orientation.
- Hollow + internal wiring design prevents cable entanglement and ensures a safe, clean working environment.
- Crossed roller bearings and deep groove ball bearings achieve high precision and load capacity.
Computing and AI Infrastructure
- 8-core high-performance CPU in the body, 8-core CPU + 10 TOPS AI processing unit in the head module.
- AI processing power can be upgraded to 40-100 TOPS with optional NVIDIA Jetson Orin module, enabling local execution of complex computer vision and deep learning models.
- RGB and depth map interfaces (Horizontal 146°, Vertical 124°) provide real-time 3D perception via the binocular module.
- WiFi 6 and Bluetooth 5.2 support low-latency communication and peripheral sensor integration.
Software and Secondary Development
- Fully open program interfaces for underlying system, robotic arm, audio, lighting and visual control.
- Drag-and-drop teaching support enables intuitive programming of complex tasks.
- OTA (Over-The-Air) update support enables remote software and firmware updates.
- End-effectors can be changed in seconds via quick-change mechanism; options include 2-finger gripper, 3-finger dexterous hand or 5-finger dexterous hand.
