Arms, Waist and Head
  • 7 degrees of freedom per arm, two arms, on low-inertia inner-rotor joint motors.
  • 19 total degrees of freedom on the desk-mount R1-A7, and 22 on the R1-A7-D with its wheeled chassis.
  • Forearm plus upper arm 555 mm (21.9 in) of reach.
  • 2 to 4 kg (4.4 to 8.8 lb) per arm, and Unitree is explicit that the figure moves a long way with arm extension.

  • Waist yaw ±150° on the desk-mount, ±35° on the mobile base. Head yaw ±115°, pitch ±36°.
  • Crossed-roller and deep-groove ball bearings, hollow internal wiring, dual encoders on the arm joints, local air cooling.
Sensing, Compute and Interaction
  • Binocular head camera, RGB at 1280 x 720 at 30 Hz and depth at 544 x 448 at 10 Hz.
  • Binocular field of view 146° horizontal by 124° vertical, eye spacing 60 mm (2.4 in).
  • 8-core CPU in the body and an 8-core CPU with 10 TOPS in the head as standard.
  • Optional NVIDIA Orin module, 40 to 100 TOPS, for running your own perception and policy models on board.
  • 4-array microphone and dual 3 W speakers for voice interaction.
  • Wi-Fi 6 and Bluetooth 5.2. Optional wrist cameras. The R1-A7-D adds a chassis LiDAR.
  • Open interfaces for the underlying system, the arms, audio, lighting and vision, with full secondary development support.
Mounting, Power and Honest Limits
  • R1-A7 desk-mount measures 835 x 357 x 190 mm (32.9 x 14.1 x 7.5 in) and weighs about 13 kg (29 lb).
  • R1-A7-D on the mobile base is 683 x 520 x 440 mm (26.9 x 20.5 x 17.3 in) collapsed and rises to 1,600 mm (63 in), at about 32 kg (71 lb).
  • About 1.5 hours on battery. Both versions also run on external power, which is how most benchtop work is done.
  • Unitree publishes no IP rating and no operating temperature range for this platform. Treat it as indoor laboratory equipment and we will not tell you otherwise.
  • This is a torso, not a humanoid. It does not walk. If your work needs legs, the R1 Edu is the machine.
  • The arms are powerful and the structure is complex. Unitree asks operators to keep a real safety distance. Plan your workcell accordingly.
  • 12-month manufacturer warranty, serviced through Toborlife in Mountain View, California.

Compare the R1 Research Platforms

The A5 and the A7 are the same torso with different arms. The R1 Edu is the legged humanoid built on the same 420 mm (16.5 in) arm. Unitree does not publish a speed, an IP rating or a temperature range for any of them, so those rows say so rather than guess.

FAQs

Is the R1-A7 authorized for use in the US?

We confirm the equipment authorization for your exact configuration before we quote it. Unitree's published US grants under grantee code 2A5PE cover the quadrupeds, the G1, the R1 legged humanoid and the H2. None of the grants on file names the R1-A dual-arm platform, so we verify the authorization that applies to the unit you are buying, in writing, rather than pointing you at somebody else's FCC ID. You can check any grant yourself at apps.fcc.gov/oetcf/eas. FCC equipment authorization is a separate question from NDAA procurement eligibility, so if you are buying under a federal procurement rule, raise that with us first.

How long does it run on a charge?

About 1.5 hours on the battery. The desk-mount ships with an external power supply as standard and the battery is optional, so most benchtop programs simply leave it plugged in and never think about runtime. The mobile-base version carries a removable chassis battery and can also take external power.

How is the R1-A7 different from the R1-A5?

7 degrees of freedom per arm and 555 mm (21.9 in) of reach, against 5 degrees of freedom and 420 mm (16.5 in) on the R1-A5. The extra joints buy you redundancy, which means the arm can reach the same point from more than one elbow posture. That matters for obstacle avoidance in cluttered scenes and for demonstration data that looks humanlike. For straightforward benchtop pick-and-place it is budget you do not need to spend. The R1-A7 starts at $4,890 and the R1-A5 at $4,290.

How much can each arm carry, and what can I bolt onto it?

2 to 4 kg (4.4 to 8.8 lb) per arm, and Unitree states plainly that the number varies a great deal with how far the arm is extended. The wrist takes a two-finger gripper, a three-finger force-controlled hand or a five-finger dexterous hand, and the end interfaces are open if you are building your own. The No Hands configuration exists for exactly that.

Desk-mount or mobile base?

The desk-mount R1-A7 is a fixed workcell: it costs less and it is the right answer if your tasks stay on one bench. The R1-A7-D puts the same torso on a wheeled chassis with a powered lifting column that raises it to 1,600 mm (63 in), plus a chassis LiDAR, so it can navigate a lab and work at varying heights. Buy the mobile base for mobile manipulation research, not for the extra height alone.

Do you accept purchase orders?

Yes. We work with universities, research institutes and public agencies regularly and accept purchase orders and tax-exempt purchasing. Tell us what your procurement office needs and we will format the quote to match, including vendor registration and W-9 documentation.
