Three-Finger Dexterous Hand Dex3-1

Unitree G1-D Ultimate C-U8 is equipped with two force-controlled three-finger hands Dex3-1 Force-Controlled Three-Finger Dexterous Hand with tactile feedback and a built-in RGB camera. Each hand has 7 degrees of freedom (thumb 3 DoF, index 2 DoF, middle 2 DoF), 33 tactile sensors, weighing approximately 650 g, and dimensions of 175x88x77 mm. The tactile system provides precise perception of pressure, friction, and contact direction, allowing delicate operations to grasp, hold fragile items, and collect high-quality multimodal data. The built-in RGB camera in each hand provides additional visual control directly in the capture area.

The manipulation system, along with 7-DoF arms, 2-DoF waist, lifting column, 7-DoF Dex3-1 hands, and 2-DoF chassis, forms a total of 33 degrees of freedom. Each arm has a working radius of about 0.45 m and a load capacity of up to 3 kg. The waist provides a range of motion Z: ±155°, Y: -2.5° ~ +135°, and the lifting column with a stroke of 450 mm, positioning accuracy of 1 mm, and lifting speed up to 60 mm/s allows reaching a working height of approximately 2 meters.

Multisensory Perception System

Operating Recommendations

• Plan work sessions considering battery life: approximately 2 hours for the upper part and approximately 6 hours for the chassis.
• For manipulation tasks, check the arm position, as the maximum load of up to 3 kg heavily depends on the manipulator's reach and position.
• Use data from 33 tactile sensors of Dex3-1 for calibrating grip force for specific objects and materials.
• Consider the capabilities of the built-in RGB cameras in the Dex3-1 hands, providing detailed visual control directly in the capture area.
• For navigation tests, leave enough space for the base to turn on the spot at 360°.
• Before data collection, set a clear task sequence: scenario creation, assignment, collection, annotation, verification, storage, and export.
• During machine learning tasks, check model compatibility with open-source datasets and frameworks such as PI or GROOT.
• Regularly calibrate the tactile sensors of the Dex3-1 hands before long sessions of tactile data collection.
• When working with fragile or non-standard objects, start with low grip force values and gradually increase it using tactile feedback.
