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.

Buying through Robotix Market
