The Unitree Dex3-1 is a three-finger, force-controlled robot hand used with the Unitree G1 humanoid. It carries 7 degrees of freedom: 3 joints in the thumb and 2 each in the index and middle fingers; its 6 direct-drive and 1 geared micro brushless joints run with hybrid force and position control. It weighs 710 g, has ±2 mm fingertip repeatability and a 500 g load.
The optional tactile array carries 33 sensors per hand. The Dex3-1 is the hand with the widest support in Unitree's software repositories: a unitree_sdk2 example, xr_teleoperate teleoperation, Isaac Lab tasks, a LeRobot configuration and a URDF model are published. As the official distributor of Unitree Robotics in Turkey, Robotlar.org handles Dex3-1 supply, with a G1 or on its own, through a corporate quotation.

Values from Unitree's Dex3-1 and G1 pages, 13 November 2026. The tactile array appears as an option on the G1 page and as a separate choice on the G1-D page. Left or right hand is set in the quotation.
The Dex3-1 carries 7 degrees of freedom: 3 in the thumb and 2 each in the index and middle fingers.
The hand has 6 direct-drive and 1 geared micro brushless joint, all force-controlled.
The manufacturer publishes two micro joint motors: the F-1515-108 (0.76 N·m ideal, 23 rad/s, 45 g) and the F-1515-214 (1.498 N·m ideal, 11 rad/s).
The G1 page states that a tactile sensor array can optionally be installed on the Dex3-1.
The Dex3-1 is the hand module with the widest support in Unitree's software repositories.
Unitree states that the Dex3-1 can be used with the G1 and publishes an official removal and installation guide for the G1 Flagship A and B versions.
Thumb 3, index 2, middle finger 2 joints.
Hybrid control; force in contact, position in free motion.
6 direct-drive and 1 geared micro brushless joint.
33 sensors in 9 arrays; 10 g to 2,500 g.
The Unitree Dex3-1 is a candidate for all of these jobs; in each scenario our catalogue also holds other bodies that can do the same work. The right robot follows from the job itself and the delivery timeline.
The lab runs XR teleoperation on the G1 with the Dex3-1, records demonstration data with the unitree_lerobot configuration and trains the policy with Isaac Lab tasks. Because this path is ready in Unitree's repositories, setup time shortens.
On the tactile version the 33 sensors in the palm, pads and fingertips measure contact pressure, and the team sets the force limit on fragile objects with this data. Hybrid force and position control helps keep contact soft.
The three-finger layout and 7 joints let students work on force control and grasp planning with a small joint count. SDK examples and the URDF model connect the simulation and real-robot parts of the course.

The most common questions about the Unitree Dex3-1.
The Unitree Dex3-1 is a force-controlled robot hand with 7 degrees of freedom across three fingers: thumb 3, index 2, middle finger 2 joints. It runs hybrid force and position control with 6 direct-drive and 1 geared micro brushless joints.
Unitree states that the Dex3-1 can be used with the G1, and there is an official removal and installation guide for the G1 Flagship A and B. The G1-D page lists the 3-finger hand with no-tactile and tactile options; the H2 and R1 pages also list a 3-finger hand option.
Optionally, yes. The tactile array carries 33 sensors in total in 9 arrays per hand (palm, pads and fingertips); the range is 10 g to 2,500 g. The G1 page describes the array as optional.
It weighs 710 g (0.71 kg) and measures 175 x 88 x 77 mm in the flat position. The load is 500 g (palm down and up); peak power is 400 W for 3 seconds.
USB 2.0 with 1000 Hz communication. Supply is 12 to 58 V; at 58 V the static current is 0.2 A, and the maximum current is 10 A.
Yes. Unitree's xr_teleoperate tool supports the Dex3-1 with the --ee dex3 option; unitree_sdk2 has a G1 Dex3 example, unitree_sim_isaaclab has Dex3 tasks, unitree_lerobot has a Dex3 configuration and unitree_ros has the URDF model.
The Dex3-1 has three fingers, 7 DoF and weighs 710 g; the software path for the G1 is ready. The Dex5-1 has five fingers, 20 DoF (16 active) and weighs 1,100 g; its fingertip force is 10 N and its load reaches 4.5 kg. If the full range of human objects has to be grasped with five fingers, the Dex5-1 stands out; if a quick start on the G1 is needed, the Dex3-1 does.
Robotlar.org is the official distributor of Unitree Robotics in Turkey. List prices are not published for Unitree products; the price is set in a corporate quotation by left or right hand, the tactile array, quantity and whether it is bought together with a G1.
