Each hand offers 7 degrees of freedom and utilizes 7 miniature brushless joints with force control. Hybrid force and position control allows for precise movement control, and the positioning repeatability of the fingertip is ±2 mm. Communication at a frequency of 1,000 Hz, a USB 2.0 interface, and a wide range of feedback data enable complex manipulations and precise control of the mechanism’s operation.\u003c\/p\u003e\n\u003cp\u003e\n\u003cimg alt=\"A silver-and-black Unitree robot with a blue light on its head sits at a table holding a plastic bottle and a glass\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/24824\/32600\/1-e52c73fc-7729-4718-8c4f-dbfe68ad9000.jpg\"\u003e\n\u003c\/p\u003e\u003ch3\u003e7 degrees of freedom for precise movement\u003c\/h3\u003e\n\u003cp\u003eEach Dex3-1 hand has three movable fingers—the thumb has 3 degrees of freedom, the index finger has 2, and the middle finger has another 2. The range of motion of each joint allows for complex grip configurations—for the thumb, it ranges from -60° to 60°, from -35° to 60°, and from 0° to 100°, while the joints of the index and middle fingers operate within ranges of 0° to 90° and 0° to 100°, respectively. This design allows the fingers to be repositioned in multiple planes and their arrangement to be adjusted to the task at hand. The positioning repeatability of the fingertip at ±2 mm further supports tasks requiring consistent movement reproduction.\u003c\/p\u003e\n\u003cp\u003e\n\u003cimg alt=\"A silver-and-black Unitree robot with a blue light on its head places objects into a blue container on the table\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/24824\/32600\/3-b668a387-7368-45ef-be33-cc640f12d37a.jpg\"\u003e\n\u003c\/p\u003e\u003ch3\u003eHybrid Force Control and Advanced Joints\u003c\/h3\u003e\n\u003cp\u003eThe UNITREE Dex3-1 utilizes hybrid force and position control, meaning control is not limited solely to setting a specific finger position. The design of each hand includes 6 miniature, directly driven brushless force-control joints and 1 joint using a geared drive. The F-1515-108 and F-1515-214 models are used, and the system allows for the control of parameters such as torque, angle, angular velocity, stiffness, and damping. For the F-1515-108, the ideal maximum torque is 0.76 Nm, while the actual torque reaches 0.49 Nm in the direction of rotation and 1.37 Nm in the opposite direction. For the F-1515-214, these values are 1.498 Nm for ideal torque and 0.86 Nm and 3.1 Nm for actual torque, respectively.\u003c\/p\u003e\n\u003cp\u003e\n\u003cimg alt=\"A silver-and-black Unitree robot with a blue light on its head is building a tower of colorful blocks on a white table\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/24824\/32600\/2-f859ca4a-3060-4f95-bbfc-6bd837e1122c.jpg\"\u003e\n\u003c\/p\u003e\u003ch3\u003eComprehensive Operational Feedback Data\u003c\/h3\u003e\n\u003cp\u003eThe system provides a wide range of information regarding the current state of the mechanism. Sensing data includes the joint’s mode, position, velocity, torque, and temperature, as well as voltage, current, and IMU data.

A full data packet is 1,234 bytes on the transmit side and 1,270 bytes on the receive side. The joint control frequency is also 1,000 Hz, and High Speed Unibus is used for joint communication. These parameters provide access to a large amount of information about the hand’s status and enable frequent updates to control parameters during the execution of complex motion sequences.\u003c\/p\u003e\n\u003cp\u003e\n\u003cimg alt=\"A black robotic gripper next to the transparent outline of a human hand against a dark background\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/24824\/32600\/5-2327c227-3b59-445c-88fc-5d5cee305913.jpg\"\u003e\n\u003c\/p\u003e\u003ch3\u003eDesign tailored to the UNITREE G1 robot\u003c\/h3\u003e\n\u003cp\u003eA single hand weighs 710 g, and its dimensions when extended are 175 × 88 × 77 mm.
