Unitree R1-A7 Smart H Dual-Arm Humanoid Robot

Description

The Unitree R1-A7 Smart H is a Smart package of the R1-A7, Unitree's fixed-base dual-arm humanoid with seven-joint arms, for teams that write their own robot software. Unitree opens the R1-A7 down to the underlying system: the arms, audio, lighting and visual control all have open interfaces, the binocular module exposes RGB and depth-map streams, and the robot takes smart OTA updates.

The hardware underneath is built for precise, repeatable motion. Each arm joint has a dual encoder, the motors are low-inertia inner-rotor units designed for fast response and heat dissipation, the output bearings combine crossed rollers with deep-groove balls, and the wiring runs inside hollow joints. Two 7-DOF arms with 555 mm of forearm and upper arm, ±0.1 mm end-clamp accuracy and 2–4 kg of payload depending on posture make it a platform for imitation-learning data collection, teleoperation and two-handed manipulation research.

Smart H is one of eight R1-A7 Smart packages, A to H, built on this robot and sold as separate packages. Its end effector (two-finger gripper, three-finger or five-finger dexterous hand), any wrist camera and any high-computing module are itemised on the quotation. The R1-A5 Smart H is a different robot, the five-joint R1-A5, with its own package.

Compute is split between an 8-core CPU in the body and an 8-core CPU with 10 TOPS of AI compute in the head. The robot weighs about 13 kg on external power, measures about 835 × 357 × 190 mm and has a waist that turns ±150°.

Key Capabilities

Open down to the underlying system: The system layer, arms, audio, lighting and visual control all have open interfaces for secondary development.
Dual encoders on the arms: Each arm joint carries two encoders for precise position feedback.
Responsive joint motors: Low-inertia inner-rotor motors with crossed-roller and deep-groove ball output bearings drive every joint.
RGB and depth streams: The binocular head camera exposes both streams to your own perception code.
Seven-joint arms for data collection: Two 7-DOF arms suit teleoperation, imitation-learning data collection and two-handed manipulation research.
Smart H items itemised: The end effector and any wrist camera or high-computing module in Smart H are listed on the quotation.

Frequently Asked Questions

What is the price of Unitree R1-A7 Smart H Dual-Arm Humanoid Robot?

The Unitree R1-A7 Smart H Dual-Arm Humanoid Robot is priced at $8,590 in your market.

What can I program on the R1-A7 Smart H?

Unitree opens the underlying system and the arm, audio, lighting and visual-control interfaces for secondary development, and the binocular camera exposes RGB and depth-map streams. Unitree's secondary development manual covers the details.

Is the R1-A7 Smart H the same as the R1-A5 Smart H?

No. The R1-A7 Smart H has seven-joint arms with 555 mm of forearm and upper arm and weighs about 13 kg; the R1-A5 Smart H has five-joint arms with 420 mm and weighs about 11 kg. They are separate packages of two different robots.

Can the R1-A7 Smart H be used for teleoperation and data collection?

Its seven-joint arms are well suited to it, because a human operator's arm posture maps directly onto them. Teleoperation equipment is not part of the robot's specification; tell us your setup and it is confirmed with the quotation.

What does the Smart H package include?

The R1-A7 robot with its arms, waist, head, cameras, computers, microphones, speakers and charger, plus the Smart H items: the end effector and any wrist camera or high-computing module, each listed on the quotation.

How is the R1-A7 Smart H supplied and supported?

It is sourced new through established distribution channels, ships worldwide and carries Unitree's 12-month manufacturer warranty, with technical support coordinated through Unitree's own service network. On-site installation is not included.
