Humanoid Robot Unitree G1-D Standard D-U4 Stationary Platform for Production and Model Training

Unitree G1-D Standard D-U4 is a modern stationary dual-arm humanoid robot on a fixed base, designed for data collection, high-precision testing of manipulation algorithms, and artificial intelligence model training. This modification includes the full set of features of the G1-D Standard A version, but instead of the standard Dex1-1 grippers, it is equipped with two advanced five-finger robotic hands BrainCo Five-Finger Dexterous Hand Revo 2 Basic Edition. The platform has an overall design with 29 degrees of freedom (DoF), a high-performance computing core, an integrated vision system, built-in RGB cameras in the hands, and a reliable fixed base for stable operation in laboratory or production environments.

Key Technological Advantages of the D-U4 Modification

• Total number of degrees of freedom 29 DoF. The robot's kinematic scheme is optimized for dual-arm tasks and includes: 7 DoF for each arm (14 in total), 2 DoF for the waist, 1 DoF for the vertical column, and 6 DoF for each five-finger BrainCo hand (12 in total).
• Five-finger dexterous BrainCo hands. Instead of basic grippers, the model received Revo 2 Basic Edition robotic hands with an anthropomorphic structure. Each hand has 6 degrees of freedom and 11 joints, providing high movement accuracy and repeatability at the level of 0.1°. The height of the hand is 160 mm (from the base to the tip of the middle finger).
• Integrated RGB cameras in the hands. The five-finger dexterous hands are equipped with built-in RGB cameras, ensuring direct visual control of the work area at the finger level and expanding the possibilities for collecting multimodal data.
• Fixed base for maximum stability. The stationary base attachment eliminates body oscillations and guarantees perfect accuracy and stability during complex precision manipulations.
• Dual-arm humanoid architecture. The presence of two symmetrical arms allows modeling the synchronous work of the human upper body, implementing scenarios of dual-hand object holding and complex technological operations.
• Adjustable telescopic column. The vertical axis (1 DoF) allows flexible changes in the working height of the robot's torso, adjusting the reach zone for different stand or work surface configurations.
• Comprehensive sensory perception system. The combination of the main computer vision system (main cameras) and local RGB cameras directly in the hands creates a complete picture of interaction with the environment.
• Powerful computing for AI and robotics. The computing unit is designed for real-time processing of sensory streams, execution of control algorithms, simulation testing, and deployment of machine learning models.
• Wireless interfaces and updates. The model supports modern communication standards Wi-Fi and Bluetooth, as well as the Upgraded Intelligent OTA cloud update technology.
• Readiness for secondary development. The platform provides flexible tools for programming and integration (Secondary Development) into existing research or production ecosystems.
• Official warranty. The entire equipment complex is covered by a 12-month manufacturer warranty.

Architecture and Functionality

Unitree G1-D Standard D-U4 combines the advantages of anthropomorphic kinematics and industrial stability. The robot's foundation is a fixed base with a telescopic vertical column, on which a torso with two 7-axis manipulators is mounted. The main distinction of the model is the integration of unique five-finger hands BrainCo Revo 2 Basic Edition (6 DoF each), bringing the total number of degrees of freedom of the system to 29 DoF.

This configuration allows for precise reproduction of fine human hand motor skills. The robot can smoothly grasp, move, rotate, and position objects of complex geometry. The fixed stable platform fully compensates for dynamic loads, ensuring perfect repeatability of actions during cyclic tests.

Precision and Interaction with Objects

Thanks to the use of dexterous BrainCo Five-Finger Dexterous Hand, the D-U4 model reaches a new level of interaction with objects. The design of each hand includes 11 joints with a repeatability index of 0.1°. This allows the robot to adapt to the shape and stiffness of any parts, tools, or household objects.

The anatomical dimensions of the hand (height 160 mm from the wrist to the fingertip) and the presence of local RGB cameras allow the operator or algorithm to see the contact point with the object in detail. The model is an excellent tool for practicing skills in delicate handling of objects, collecting multimodal tabletop datasets, and implementing teleoperation technologies.

Data Processing and AI Training System

The model is oriented towards the full development cycle in the field of artificial intelligence for robotics (Embodied AI). Thanks to the combination of the main vision system and cameras on the hands, Unitree G1-D Standard D-U4 effectively collects spatial data.

The platform supports task generation, labeling, storage, verification, and export of interaction data. It is compatible with open robotic frameworks and simulation environments, allowing neural networks to be trained in a virtual environment (Sim-to-Real) with subsequent seamless deployment of algorithms on real hardware. The D-U4 modification is ideal for scientific laboratories, R&D centers, and innovative productions exploring dual-hand manipulations and fine finger motor skills.

Power System and Autonomy

Unitree G1-D Standard D-U4 is designed for stationary use in laboratories or production sites. The platform is equipped with a built-in intelligent power management system with BMS (Battery Management System) support, which monitors voltage, current, charge level (SOC), temperature, and power element status in real-time. Protective algorithms safeguard the system from current overloads and overheating.

Since the model is oriented towards continuous data collection and prolonged machine learning model training, it is recommended to connect it to a stable network power source. The exact electrical parameters, power of the included power supply, and connection configuration features should be clarified when placing an order.

Application Profile Vectors

Thanks to the unique combination of a dual-arm humanoid design, a fixed stable base, and the integration of anthropomorphic five-finger BrainCo robotic hands with built-in RGB cameras, Unitree G1-D Standard D-U4 opens up broad possibilities for complex applied and scientific tasks:

• Collection of multimodal data for Embodied AI: forming detailed datasets based on high-precision visual control and movement coordination.
• Training fine motor skills: developing algorithms for complex gripping, manipulation of small and flexible objects with anthropomorphic precision.
• Testing control algorithms for dexterous hands: debugging software for 5-finger robotic hands with 6 degrees of freedom and high movement repeatability.
• Research in the field of human-machine interaction (HRI): developing and testing scenarios for safe contact and object transfer.
• Working with leading AI models: integrating the platform with open robotic frameworks, datasets (open-source datasets), as well as PI, GROOT architectures, etc.
• Scenarios for commercial and industrial sectors: simulation and automation of tasks in Service, Life, Retail, and Industry areas (sorting, packaging, assembling electronic components).

Compatibility

The Unitree G1-D Standard D-U4 robotic platform has a high level of compatibility with modern open robotic ecosystems, including PI and GROOT frameworks. The BrainCo Five-Finger Dexterous Hand Revo 2 Basic Edition hands integrate with the control system through reliable communication interfaces and support visual data collection through their own cameras. For quick integration, remote monitoring, and data transmission, the robot is equipped with advanced wireless modules Wi-Fi and Bluetooth.

Technical Specifications

Operating Recommendations

• Session planning and power supply: during prolonged data set collection and AI calculations, ensure uninterrupted network power supply for platform stability.
• Kinematics control: before starting precision manipulations, calibrate the initial position of the robot's arms. The accuracy of task execution directly depends on the correct positioning of the end effector.
• Using the advantages of the 5-finger design: consider that BrainCo hands have high repeatability (0.1°) and 11 joints, program trajectories taking into account the anthropomorphic specificity of the fingers.
