Unitree G1-D Standard A U1 Fixed Base Dual-Arm Wheeled Humanoid Robot (Coming Soon)

Unitree G1-D Standard A U1 Fixed Base Dual-Arm Wheeled Humanoid Robot (Coming Soon)

The G1-D Standard A U1 is configured with two Dex1-1 force-controlled two-finger grippers as its standard end-effectors — making it the entry-level manipulation configuration in the G1-D Standard lineup, optimized for general pick-and-place, object transport, and straightforward grasping tasks that do not require three-finger or five-finger dexterity.  Key confirmed specifications include: 17 total degrees of freedom (excluding end effectors: 7 DOF × 2 arms + 2 DOF waist + 1 DOF column = 17), height adjustable from 1,260 to 1,680 mm with a 500 mm vertical lifting stroke at 1 mm precision, 3 kg maximum single-arm payload, 450 mm arm reach (excluding end effector), NVIDIA Jetson Orin 16GB (100 TOPS) AI compute, 1920×1080 wrist cameras (FOV 130°×60°×160°), a 3840×1200 stereo vision head camera (FOV 115°×80°×125°), WiFi 6, Bluetooth 5.2, a 4-microphone array, 5W speaker, OTA update support, and a 9,000 mAh smart battery providing approximately 2 hours of runtime with a quick-release mechanism and direct power connection option. Total weight with battery is approximately 50 kilograms. The package includes a handheld controller, visualization computer, and full secondary development support with a 12-month warranty.

The G1-D family divides into two principal mobility tiers: the Standard (fixed base) and the Flagship (mobile wheeled base). The Standard tier is further divided into multiple sub-configurations (Standard A through Standard E and beyond on RobotShop) that differ primarily in their end-effector type:

• Standard A (U1): Two Dex1-1 two-finger grippers — baseline general manipulation
• Standard B: Dex3-1 three-finger hands without tactile
• Standard C: Dex3-1 three-finger hands with tactile sensors
• Standard D: BrainCo Revo 2 Basic five-finger hands
• Standard E: BrainCo Revo 2 Touch five-finger hands with multi-modal tactile

All Standard configurations share the same fixed-base body platform — the 17-DOF body with height-adjustable column, dual 7-DOF arms, 2-DOF waist, identical sensor system, and Jetson Orin compute. The Standard A U1's Dex1-1 grippers represent the entry-level manipulation configuration that prioritizes cost-effectiveness, simplicity, and reliability for pick-and-place tasks over the dexterity of three-finger or five-finger alternatives.

The fixed-base design was a deliberate engineering choice for the Standard tier. RobotShop's description explains the design rationale: "Mounted securely on a baseplate, it eliminates the challenges of balance and locomotion, allowing users to focus on manipulation, AI training, or interface development in a controlled setup." For laboratory research, fixed workstation data collection, and fixed industrial applications, the stability of a fixed base eliminates the complexity and cost of mobile navigation while providing the full upper-body arm articulation needed for meaningful manipulation research.

Design and Physical Features

Fixed-Base Architecture

The G1-D Standard A's defining physical characteristic is its fixed baseplate mounting — the robot does not move across a floor, but instead provides a stable, high-mass anchoring for arm operations that might otherwise disturb the robot's position during high-force or fast manipulation tasks. The fixed design contrasts with the Flagship's 80-kg mobile base (which includes the wheeled drive system, LiDAR, and depth cameras) and enables deployment at a laboratory bench, workstation, or production fixture without requiring floor space for navigation.

At approximately 50 kilograms total weight with battery, the G1-D Standard A is substantially lighter than the Flagship configuration — reflecting the absence of the mobile base hardware — while remaining heavy enough to provide stable anchor for the dual arm operations.

Height-Adjustable Column: 1260 to 1680 mm with 500 mm Stroke

The 500 mm vertical lifting stroke of the height-adjustable column is one of the most operationally significant features of the G1-D Standard A. With 1 mm precision in height adjustment, the robot can be precisely positioned to match the exact height of a workstation, conveyor, shelf, or fixture — enabling accurate and repeatable arm approach trajectories to work surfaces at any height within the 1,260 to 1,680 mm range.

This height adaptability enables a single G1-D Standard A installation to serve multiple different workstation heights by adjusting the column elevation before each task configuration — providing versatility within a fixed-base form factor that would otherwise require hardware repositioning to reach differently sized work surfaces.

Dual 7-DOF Arms: 3 kg Payload, 450 mm Reach

Each arm of the G1-D Standard A provides 7 degrees of freedom covering the full shoulder-to-wrist workspace with wrist articulation in both pitch and yaw. The 450 mm arm reach (excluding the end effector) combined with the height-adjustable column means the robot's effective working volume covers the height range from 1,260 mm to approximately 1,680 mm + reach at full arm extension.

The 3 kg maximum single-arm payload is consistent with the G1-D family's specification across all configurations, covering the weight range of standard industrial and logistics components, laboratory equipment, and service objects within the arm's rated capability.

Dex1-1 Two-Finger Grippers: Standard A's End-Effectors

The Dex1-1 is Unitree's force-controlled two-finger gripper — a parallel-jaw gripper design with force control enabling it to grip objects at a regulated grip force rather than simply closing to a fixed position. The Dex1-1 is the simplest end-effector option in the G1-D family, covering the pick-and-place tasks that represent the majority of robotic manipulation use cases: cylindrical objects, boxes, bags, packaged goods, and components within the jaw's opening range.

Importantly, the G1-D Standard lineup is designed for end-effector upgrades: the same mounting interface supports Dex1-1, Dex3-1 three-finger hands (with or without tactile), and five-finger dexterous hands. Buyers who start with the Standard A U1 can upgrade end-effectors for different task configurations by contacting Unitree's sales team, per the RobotShop documentation.

Binocular Head Camera and Dual Wrist Cameras

The G1-D Standard A's camera system is comprehensively documented in Robots International's specification:

Stereo Head Camera: 3840×1200 resolution, FOV 115°×80°×125° — a high-resolution stereo vision system providing workspace overview and egocentric depth perception for autonomous task planning and teleoperation monitoring.

Wrist Cameras (bilateral): 1920×1080 resolution per camera, FOV 130°×60°×160° — the hand-level visual data capture most critical for manipulation AI training. The 130-degree horizontal FOV at the wrist ensures the camera captures the complete contact zone between the hand and the manipulated object from the approaching direction.

Technology and Specifications

Full G1-D Standard A (U1) Specifications

NVIDIA Jetson Orin 16GB (100 TOPS) and Dual-Compute Architecture

The Jetson Orin 16GB provides 100 TOPS of GPU-accelerated inference for the manipulation AI policies, visual grasping models, and UnifoLM multimodal interaction that the G1-D Standard A's research and deployment use cases require. Top3DShop confirms the architecture: "An 8-core ARM CPU for motion control and an NVIDIA Jetson Orin NX delivering 100 TOPS AI performance via 1024 CUDA and 32 Tensor cores." The 16GB memory configuration supports the large visual grasping models that modern manipulation policy research deploys.

For data collection applications, the Jetson Orin processes the simultaneous video streams from the stereo head camera and dual wrist cameras — managing data recording, annotation assistance, and the synchronization of multi-modal sensor streams that manipulation training data requires.

Direct Power Connection for Unlimited Runtime

The G1-D Standard A's direct power connection option is an important operational feature for fixed-base deployment contexts. Unlike the battery-limited 2-hour runtime, direct power connection enables unlimited operational duration — a critical advantage for data collection sessions, extended demonstration deployments, and research experiments that need to run continuously beyond battery capacity. Fixed-base robots, unlike mobile platforms, naturally lend themselves to corded power delivery since they don't need to travel across a floor.

End-Effector Upgrade Path

The G1-D Standard A's end-effector interface is shared across all Standard configurations. RobotShop's comparative table confirms: "Standard: Optional 2-Finger Gripper / 3-Finger Dexterous Hand (No Tactile) / 3-Finger Dexterous Hand (With Tactile) / 5-Finger Dexterous Hand." This means the Standard A U1's Dex1-1 grippers can be replaced with more capable end-effectors for different research tasks — contacting the sales team for end-effector selection as noted in the product documentation.

Applications and Use Cases

Fixed Workstation Data Collection for Manipulation AI

The G1-D Standard A's most directly targeted application is manipulation training data collection at fixed workstation setups. The combined stereo head camera and dual wrist cameras capture the visual observations from both the egocentric perspective and the hand-object contact perspective simultaneously — the two most important viewpoints for training visuo-motor manipulation policies. The height-adjustable column enables the workstation to be configured for any task height within 500 mm of range, and the direct power connection enables extended data collection sessions without battery management overhead.

Laboratory Research: Fixed-Base Manipulation Studies

For university robotics laboratories studying manipulation, grasping, and arm control where the researcher can control the object placement and task configuration (as opposed to mobile deployment where the robot must navigate to the task location), the G1-D Standard A provides a stable, mechanically simple research platform. The absence of locomotion complexity reduces confounding variables in manipulation studies and simplifies the experimental setup compared to working with a full mobile humanoid system.

Industrial Workstation Automation Piloting

For manufacturing facilities evaluating automation of fixed workstation tasks — assembly inspection, component sorting, packaging, and quality control — the G1-D Standard A's fixed-base architecture matches the mechanical configuration of existing fixed industrial robots (SCARA, delta, 6-axis arm) while providing the dual-arm humanoid capability for tasks requiring two hands. The 3 kg payload and 450 mm reach cover standard light industrial component weights, and the height-adjustable column enables setup for different workstation heights without reinstalling the robot.

Bench-Mounted Research and Education

The G1-D Standard A's 50 kg fixed weight and flat baseplate enable secure bench mounting — a research and education context where the robot is fixed to a laboratory bench or table at standard working height. This configuration is appropriate for hands-on robotics education, manipulation algorithm demonstration, and robot programming courses where students interact with the robot at a stationary workstation.

Service and Reception Demonstrations

For exhibition, hotel lobby, or corporate reception deployments where a humanoid robot provides a stationary interactive presence — answering voice queries with UnifoLM, gesturing with its 7-DOF arms, and demonstrating manipulation capabilities — the G1-D Standard A's stability, visual expressiveness, and WiFi 6 connectivity provide a reliable fixed-base demonstration platform without the navigation complexity of mobile alternatives.
