Unitree R1 EDU Pro A Humanoid Robot (R1 EDU U3)
$18,540
Unitree R1 EDU Pro A (R1 EDU U3) adds articulated manipulation to the 100-TOPS R1 development platform. U3 combines the 26-DOF R1 body with two Dex3 three-finger hands, each with 7 actuated DOF, for 40 actuated DOF in the full configuration. The hands are dexterous but do not include tactile sensing on this U3 tier. Manufacturer model / part number: R1-EDU-U3.
With secondary-development support, binocular vision and NVIDIA Jetson Orin compute specified at 100 TOPS, U3 is designed for robotics labs, manipulation research, embodied AI and advanced education.

Dexterous R1 development robot
Unitree R1 EDU Pro A U3
Unitree R1 EDU Pro A U3 is where the R1 family moves from locomotion-and-perception development into articulated object manipulation. The base R1 body contributes 26 actuated joints, while two Unitree Dex3 three-finger hands add 7 actuated DOF per hand. The result is a 40-actuated-DOF configuration designed for grasping, coordinated arm-hand control and embodied-AI research.
U3 also uses the higher R1 EDU compute tier, specified with NVIDIA Jetson Orin at 100 TOPS, and supports secondary development. Unlike tactile variants, the U3 Dex3 configuration does not include tactile arrays, which makes it a useful choice when articulated motion is required but touch sensing is not.

Manipulation platform
Why U3 matters for humanoid manipulation research
Fixed-hand humanoids can demonstrate locomotion and interaction, but they cannot perform meaningful grasping experiments. U3 changes that equation by adding articulated hands while retaining the compact R1 chassis. Researchers can explore coordinated whole-body movement, reaching, grasp planning, tool interaction and hand-arm trajectories without moving to a much larger robot.
The Unitree R1 U3 is therefore a different purchasing decision from R1 EDU U2. Both use the 100-TOPS development tier, but U2 keeps fixed hands while U3 introduces Dex3 articulation. If tactile sensing is essential, compare R1 EDU U6 instead.
Dex3 configuration
Two three-finger Dex3 hands, 7 actuated DOF per hand, no tactile sensors on U3. This distinction should be confirmed in the written quotation because hand options materially change capability and price.
Buying decision
R1 EDU Pro A U3 price and project fit
The listing price shown above applies to the U3 configuration on AI Robot Supplier. For dexterous robots, compare the complete scope—not only the chassis price. The hand pair, compute module, protective gantry, transport case, spare batteries and development support can materially affect the delivered system cost.
100-TOPS onboard compute
The higher compute tier supports real-time perception, AI inference and manipulation-control workloads.
Compact research footprint
At roughly 1.23 m and 29 kg, R1 is physically easier to accommodate than full-size humanoids while still offering whole-body articulation.

Hand and compute comparison
R1 U3 vs U2 and U6
R1 EDU U2 gives you the same 100-TOPS compute tier with fixed hands, making it more economical for perception and locomotion work. U3 adds two 7-DOF Dex3 hands but no tactile sensing. R1 EDU U6 moves to a five-finger tactile-hand configuration for contact-rich manipulation. The U1 remains the lower-compute 40-TOPS entry EDU option.
For buyers comparing “40 DOF humanoid robot” listings, check how the total is counted. U3’s 40 figure is straightforward: 26 actuated body joints plus 14 actuated hand joints.
| Feature | U2 | U3 | U6 |
|---|---|---|---|
| R1 body DOF | 26 | 26 | 26 |
| Published total actuated DOF | 26 | 40 | 48 |
| AI compute | 100 TOPS | 100 TOPS | 100 TOPS |
| Hands | Fixed | 2 × Dex3, 7 DOF each | 2 × Revo 2 Touch, 11 DOF each |
| Tactile sensing | No | No | Yes |
| Best fit | AI/perception | Articulated grasping | Contact-aware manipulation |
Dexterous research package
What is commonly included with R1 EDU U3
A typical U3 system includes the R1 EDU U3 robot, two Unitree Dex3 three-finger hands, quick-release battery, charger, handheld controller, transport case and protective gantry. The two Dex3 hands provide 7 actuated DOF each and are non-tactile on this configuration.
Two Dex3 hands
Articulated three-finger hands add 14 actuated joints to the 26-DOF R1 body.
100-TOPS compute
Supports perception, manipulation policies and other custom development workloads.
Protective lab hardware
Transport case and protective gantry are commonly part of the research-oriented U3 package; verify final packing.
Dex3 limits
Dexterous does not mean tactile on U3
U3 provides articulated grasping but does not include tactile sensors in the Dex3 hand configuration described here. If your research depends on contact sensing, grip feedback or multimodal touch data, U6 is the more appropriate R1 variant. Manipulation performance also depends on the chosen control stack, object geometry and whole-body posture.
40-DOF architecture
How Unitree R1 EDU Pro A reaches 40 actuated DOF
Unitree R1 EDU Pro A combines the standard 26-DOF R1 body with two Unitree Dex3 three-finger hands. Each Dex3 hand contributes seven actuated joints, so the complete U3 configuration is counted as 26 body joints + 7 left-hand joints + 7 right-hand joints = 40 actuated DOF.
That simple calculation is worth stating because “40 DOF” is sometimes presented without explaining where the additional movement comes from. On Unitree R1 EDU Pro A, the extra articulation is specifically in the two dexterous hands.
Dex3 manipulation
Unitree R1 EDU Pro A Dex3 hand capability
Unitree R1 EDU Pro A uses two Dex3 hands with seven actuated DOF per hand and no tactile sensors on the U3 configuration described here. This creates a useful manipulation platform for reaching, grasp planning, coordinated hand-arm control, tool interaction and whole-body manipulation research without adding the tactile sensing complexity of U6.
Because the hand system is non-tactile, contact-aware tasks must rely on vision, joint state, control models or other instrumentation rather than fingertip tactile arrays.
Compute and development
Unitree R1 EDU Pro A 100-TOPS development platform
Unitree R1 EDU Pro A is currently documented with NVIDIA Jetson Orin at 100 TOPS, Unitree SDK2 with CycloneDDS, ROS 2 workflows including rosbag2 and MoveIt2, and NVIDIA Isaac Sim support. That combination is relevant to manipulation teams because perception, trajectory generation and dexterous control can be compute intensive.
The usual U3 research package is commonly listed with two Dex3 hands, smart battery, charger, handheld controller, transport case and protective gantry. Confirm the exact U3 model code and supplied accessories in the final quotation.
Unitree R1 EDU Pro A should be selected by exact configuration rather than by family name alone, because compute, hand hardware, development access and supplied accessories can materially change between variants.
Included-system planning
What to confirm before ordering U3
