Unitree R1-A7-D
The Unitree R1-A7-D is the wheeled configuration of Unitree's R1-A7 dual-arm humanoid, mounting two 7 degree of freedom arms on a LiDAR equipped mobile base with a self raising column that extends from 683 to 1,600 millimeters, combining ±0.1 millimeter end precision and quick-change dexterous hands with indoor navigation at roughly 32 kilograms.
Unitree R1-A7-D
Every workshop that ever bolted a robot to one bench eventually asked the same question: why can't it just roll to the next one? The Unitree R1-A7-D is Unitree's answer at a price the question never expected, the wheeled configuration of the R1-A7 dual-arm humanoid, mounting its two 7 degree of freedom arms, head and torso on a LiDAR equipped mobile base whose self raising column telescopes the machine from a compact 683 millimeters to a standing 1,600, a manipulator that shrinks to bench height for one task, rises to shelf height for the next and navigates itself between them.
The R1-A7-D completes the logic of the R1-D family, Unitree's 2026 pivot of the R1 platform from legged performer to armed worker: the fixed R1-A5 and R1-A7 hold stations, and the D variants free them, adding indoor mobility without surrendering the family's working credentials, ±0.1 millimeter end clamp accuracy, 2 to 4 kilogram arm loads and quick change tooling spanning two finger grippers and three and five finger dexterous hands across five actuator types. At approximately 32 kilograms, it is mobile manipulation at a fraction of the mass, and cost, of the category's full scale machines.
Within Unitree's range, the R1-A7-D is the accessible tier of mobile manipulation, the compact relative of the industrial H2-D and the working branch of the wheeled humanoid category. The Unitree R1-A7-D for sale, with full specifications, can be explored through this page.
Background
From R1 to R1-D: the platform grows hands, then wheels
The original R1's 2025 launch democratized bipedal humanoids and exposed their entry level limit, no useful hands, while the embodied AI economy's real demand concentrated in dual arm manipulation for stations, classrooms and data pipelines. The R1-D family answered in stages within one release: arms first, the A5 and A7 replacing legs with fixed mounts and genuine manipulation hardware, then mobility, the D variants restoring movement not as legs but as the pragmatic indoor answer, wheels, a column and LiDAR, the same conclusion the industry's warehouse humanoid deployments keep reaching at every scale.
Why the column matters
The self raising mechanism is the D variant's quiet masterstroke: manipulation workspaces live at every height, floor bins, bench tops, machine feeds, shelving, and a fixed torso must choose one. The R1-A7-D's 683 to 1,600 millimeter range lets one machine serve them all, compacting for transport and storage, working low for seated height tasks and rising to adult standing reach, vertical flexibility that full size platforms buy with mass and cost the R1-D family avoids.

How does the R1-A7-D differ from the fixed R1-A7?
Territory. The fixed R1-A7 owns one station at minimum mass and cost, the choice when the work comes to the robot. The R1-A7-D owns the room: LiDAR navigation carries the same 7 degree of freedom arms between stations, the column adapts working height task by task, and the 22 total degrees of freedom, arms plus base and lift articulation, turn multi station workflows, fetch and place errands and roaming demonstrations into one machine's job. Against its own sibling, the R1-A5-D, the A7-D's two extra joints per arm buy the reach around dexterity and human natural teleoperation mapping that harder manipulation and data collection work demands.
Technology
Navigation on the family's terms
The D base carries LiDAR for indoor mapping and autonomous movement, sized and priced for the environments the family serves, labs, classrooms, light production floors and service interiors, mobility as a working utility rather than a research problem, with the platform's conservative indoor behavior suiting spaces shared with people.
Manipulation credentials intact
Nothing working was traded for wheels: the ±0.1 millimeter end clamp accuracy, 2 to 4 kilogram arm loads and quick change tooling from grippers to five finger dexterous hands, drawn from the ecosystem behind the wider robot hands field, carry over whole, meeting the binocular RGB and depth module's workspace perception wherever the base parks.
Taught by hand, opened by SDK
The family's accessibility ladder spans the D variants: drag and drop teaching lets operators guide the arms through tasks physically, open interfaces across the underlying system, arms, audio, lighting and visual control support full process secondary development, and the optional NVIDIA Jetson Orin adds onboard AI headroom, from technician's demonstration to custom autonomy on one platform, backed by Unitree support and accessories.
Voice at every station
The four microphone array and dual speakers travel with the machine, voice collaboration wherever it works, the roaming manipulator that takes instructions, answers questions and narrates demonstrations, the interaction inheritance of its R1 ancestry.
What is the Unitree R1-A7-D used for?
- Multi station production and tending: one machine serving several benches, feeds and fixtures across industrial, factory and light warehouse floors, the roaming station worker at entry cost.
- Mobile data collection: teleoperated demonstration capture across varied real workspaces, the research data pipelines of the embodied AI era fed from a base that repositions itself.
- Laboratory and campus service: fetch, carry and place errands through educational and research facilities, manipulation that comes when called.
- Mobile manipulation research: navigation plus dual 7 DOF arms as an affordable whole, the study platform for the coordination problems full scale machines like the H2-D deploy industrially.
- Roaming demonstrations and engagement: the voice collaborating manipulator working exhibition floors and commercial spaces, arriving, rising, working and explaining.

Summary
The Unitree R1-A7-D answers the workshop's oldest wish: the skilled pair of hands that comes when called, at whatever height the job sits. LiDAR carries it between stations, the column swings it from bench crouch to standing reach, the 7 degree of freedom arms work to a tenth of a millimeter with whichever hands the task demands, and the whole machine weighs less than the toolbox it replaces trips to, taught by a guiding hand or programmed to its depths, talking as it works. As the accessible arrival of true mobile manipulation, the Unitree R1-A7-D stands as the definitive reference point in its class.
