Unitree R1-A5-D
The Unitree R1-A5-D is the wheeled entry model of Unitree's R1-D dual-arm humanoid family, pairing two 5 degree of freedom arms with a LiDAR equipped mobile base and self raising column spanning 683 to 1,600 millimeters, delivering ±0.1 millimeter end precision and quick-change hands at roughly 30 kilograms, the most affordable configuration of true mobile manipulation.
Unitree R1-A5-D
Mobile manipulation has always been robotics' most wanted and worst priced capability: an arm that comes to the work instead of waiting for it, historically costing so much that facilities bought one and scheduled around it. The Unitree R1-A5-D attacks the price, not the promise: the wheeled entry model of Unitree's R1-D dual arm family, two 5 degree of freedom arms on a LiDAR navigating base with a self raising column running 683 to 1,600 millimeters, at roughly 30 kilograms and the lowest cost of any true mobile manipulator in its class, the configuration that turns "the roaming robot" from a facility's single prized asset into something a program can fleet.
The A5-D's formula is deliberate subtraction: it takes the family's value arm set, the five joint arms of the benchtop R1-A5, and adds only what mobility genuinely requires, wheels, LiDAR and the telescoping column, while holding every working credential constant: ±0.1 millimeter end clamp accuracy, 2 to 4 kilogram arm loads, quick change tooling from two finger grippers to five finger dexterous hands, drag and drop teaching and full secondary development. Programs that need more articulation step to the R1-A7-D's seven joint arms on the identical base; programs that need more machines buy more A5-Ds, and that is precisely the point.
Within Unitree's range, the A5-D is the accessible floor of the wheeled humanoid working category, far beneath the industrial H2-D it conceptually miniaturizes. The Unitree R1-A5-D for sale, with full specifications, can be explored through this page.
Background
The family's mobility question, answered twice
When Unitree's 2026 R1-D family converted the R1 platform from legged performer to armed worker, it split each arm architecture into fixed and wheeled lives: the A5 and A7 clamp to stations, the A5-D and A7-D roam between them on a shared base design, wheels for indoor floors, LiDAR for autonomous navigation, and a self raising column that solves the height problem legs never efficiently did, compacting to 683 millimeters for storage and low work, extending to 1,600 for standing height reach. The A5-D is the split's value answer: mobility at the entry arm set, the most capability subtracted price the mobile manipulation category has seen.
Fleet mathematics
The A5-D's strategic role is multiplication. The embodied AI economy's demonstration pipelines, campus service experiments and multi station operations all scale by robot count, not robot ceiling, and a mobile manipulator light enough to ship by parcel courier and priced at the family's entry tier changes the arithmetic: three A5-Ds covering a floor where one traditional platform stood, a teaching lab running a machine per bench group, a data operation adding capture stations by the order form.

How does the R1-A5-D differ from its siblings?
Against the fixed R1-A5, the purchase is territory: the same five joint arms, freed by LiDAR navigation and the height adaptive column to serve every station on a floor rather than one, at roughly triple the mass and the mobility premium. Against the R1-A7-D, the trade is articulation for economics: the A7-D's seven joint arms and 22 total degrees of freedom serve harder manipulation and teleoperation research, while the A5-D's 18 cover the defined task repertoire, pick, place, sort, tend, carry, deliver, that most mobile deployments actually consist of, at the family's lowest wheeled price, the difference between buying reach and buying reach times three.
Technology
Navigation as a working utility
The base's LiDAR delivers indoor mapping and autonomous movement scaled to the family's habitats, laboratories, classrooms, light production floors, campuses, mobility engineered as a dependable utility for shared human spaces rather than an outdoor research frontier, with conservative behavior suiting corridors full of students and technicians.
Height as a degree of freedom
The self raising column is the base's second gift: 683 to 1,600 millimeters of working height on demand, floor bins and bench tops and shelf faces served by one machine, the vertical adaptability that fixed torsos forfeit and legged platforms buy with cost and complexity, folded here into the entry price.
The full working stack, unsubtracted
Everything that makes the family credible survives the value positioning: tenth millimeter end precision, 2 to 4 kilogram loads, five quick change actuator types into the wider robot hands ecosystem, binocular RGB and depth workspace perception, voice collaboration through the microphone array and dual speakers, drag and drop teaching for the first program, open interfaces and full secondary development for the hundredth and the optional NVIDIA Jetson Orin for onboard AI ambitions, within Unitree's support and accessories surround.
What is the Unitree R1-A5-D used for?
- Multi station coverage: one machine serving several benches, feeds and drop points across industrial, factory and light warehouse floors, the roaming worker at fleet friendly cost.
- Fetch, carry and deliver: campus and facility errands across educational and research estates, the manipulation courier that loads and unloads itself.
- Fleet scale data collection: multiplying demonstration capture stations for imitation learning pipelines, the entry price that turns capture farms into ordinary procurement.
- Mobile manipulation education: the affordable whole problem, navigate, position, raise, grasp, place, for coursework and clubs, the teaching miniature of platforms like the H2-D.
- Roaming demonstrations and service: the voice collaborating machine working exhibition floors and commercial spaces, arriving where the audience is.

Frequently Asked Questions
What is the Unitree R1-A5-D?
The R1-A5-D is the wheeled entry model of Unitree's R1-D dual arm humanoid family: two 5 degree of freedom arms, head and torso on a LiDAR equipped, self raising mobile base spanning 683 to 1,600 millimeters, totaling 18 degrees of freedom with grippers at roughly 30 kilograms, with ±0.1 millimeter end precision and 2 to 4 kilogram arm loads.
How does the Unitree R1-A5-D work?
The R1-A5-D navigates indoors by LiDAR, adapts its working height through the telescoping column, perceives through a binocular RGB and depth module, manipulates through quick change grippers or three and five finger dexterous hands, learns by drag and drop teaching or full secondary development and collaborates by voice through its microphone array and speakers, with optional Jetson Orin compute onboard.
Why is the Unitree R1-A5-D important?
It resets mobile manipulation's economics: the capability facilities historically bought once and rationed, an arm that travels, becomes fleetable, three machines where one stood, capture stations by the order form, a mobile manipulator per classroom, the multiplication that entry pricing exists to unlock.
What are the benefits of the Unitree R1-A5-D?
Key benefits include the lowest cost of true mobile manipulation in its class, LiDAR autonomy with a 683 to 1,600 millimeter height range, undiminished precision and tooling options, drag and drop teaching beside full development openness, parcel light logistics at 30 kilograms and fleet mathematics no traditional platform approaches.
What is the difference between the R1-A5-D and the R1-A7-D?
Arms and arithmetic: the A7-D carries 7 degree of freedom arms at 22 total DOF for harder manipulation and teleoperation research, while the A5-D's 5 degree of freedom arms at 18 total cover the standard mobile task repertoire at the family's lowest wheeled price, on the identical navigating, self raising base.
What is the difference between the R1-A5-D and the fixed R1-A5?
Territory: the fixed R1-A5 holds one bench at about 11 kilograms and minimum cost, while the A5-D's wheeled base and column free the same arms to serve a whole floor's stations, errands and demonstrations at roughly 30 kilograms, mobility as the entire difference.
Where can I buy the Unitree R1-A5-D and what does it cost?
The R1-A5-D is for sale through Robots International, serving markets worldwide with delivery, customs clearance and support. Because cost varies by hands and compute configuration, buyers should request a tailored quotation. Full purchasing details are available on this page.
Summary
The Unitree R1-A5-D takes robotics' most rationed capability and prices it for multiplication: a manipulator that navigates itself between jobs, rises from bench crouch to shelf reach, works to a tenth of a millimeter with swappable hands, learns from a guiding grip and speaks as it serves, at a cost and a 30 kilogram mass that make the second and third units the natural next line of the order. The value wheels of the R1-D family, beneath the A7-D's research reach and beside the benchtop A5, it closes the set that turned the R1 from performer to workforce. As the affordable arrival of the arm that comes to the work, the Unitree R1-A5-D stands as the definitive entry to mobile manipulation.
