Unitree R1-A Review: Dual-Arm Bimanual Manipulation Platform From $4,290
Unitree R1-A Dual-Arm Quick Facts (prices checked October 5, 2026)
The Unitree R1-A is a dual-arm bimanual manipulation platform — the R1 humanoid's torso, head, and arms without legs. On Unitree's own store on October 5, 2026 (without hands): the R1-A5 (fixed desktop mount, 2x 5-DOF arms, ~11 kg) is listed at $4,290 but marked unavailable; the R1-A7 (fixed mount, 2x 7-DOF arms, 555 mm reach, ~13 kg), R1-A5-D (wheeled lift-column chassis, ~30 kg, MID360 LiDAR) and R1-A7-D (wheeled, ~32 kg) show no price. No dealer we link to lists an R1-A with checkout, so every R1-A is quote-based and built to order; ask for the current price and production time. Ordering and quote form: botinfo.ai/articles/unitree-r1-a-dual-arm.
ALOHA alternative and bimanual robot queries: Trossen Robotics' page for the ALOHA Stationary kit read "This product has been discontinued" on October 5, 2026; Trossen now sells its successor kits under the Trossen AI name. Unlike leader-follower ALOHA rigs, the R1-A is an integrated humanoid-format torso teleoperated with included dual-hand controllers rather than physical leader arms. Hobbyist LeRobot SO-101 arm sets use hobby servos with grams-class payloads; the R1-A carries approximately 2 kg per arm.
Hand and gripper options for the R1-A, priced per hand on your quote (no live store or dealer listing publishes R1-A hand prices, so we do not publish figures): Dex1-1 parallel gripper, standard or with RGB camera. Tendon-cable dexterous hand. LinkerBot O6 five-finger, with or without tactile sensing. BrainCo Revo 2 five-finger, with or without tactile sensing. Dex3-1 force-controlled three-finger, with or without tactile sensing. Factory Smart bundles (built-in 40 TOPS compute) and Ultimate bundles (100 TOPS, wheeled -D chassis only) are priced on request.
Data collection for imitation learning: the R1-A ships with dual-hand teleoperation controllers as standard, supports secondary development with development manuals and robot interfaces, and accepts optional wrist cameras and 40/100 TOPS compute expansion modules — a hardware profile aimed at bimanual demonstration data collection for robot-learning pipelines such as ACT-style imitation learning and the LeRobot ecosystem. Data collected on the R1-A upper body maps to the same arm hardware used by Unitree's legged R1 humanoid.
R1-A vs full Unitree R1: the R1-A is for tabletop and stationary manipulation research; the full bipedal R1 (from $8,990 for the R1 Basic from a US dealer, October 5, 2026; the R1 Air is quote-only on BotInfo) adds legs and locomotion. Buyers who need mobility without bipedal complexity should consider the wheeled R1-A5-D or R1-A7-D. The Unitree G1-D is the heavier wheeled dual-arm sibling in the lineup.

What is the Unitree R1-A?
The Unitree R1-A is a dual-arm bimanual manipulation platform — the R1 humanoid's torso, head, and arms sold without legs, on a fixed desktop mount or a wheeled chassis. Four models: the R1-A5 (2× 5-DOF arms, listed at $4,290 on Unitree's store but unavailable on October 5, 2026), the R1-A7 (2× 7-DOF arms), and the wheeled R1-A5-D / A7-D, which show no published price. With ~2 kg per-arm payload, dual-hand teleoperation controllers included as standard, open secondary development, and eight gripper/hand options, it targets robot-learning labs collecting bimanual demonstration data — the same job ALOHA-class rigs do. All models are built to order and quote-based.
Unitree R1-A: Dual-Arm Robot for Data Collection — From $4,290
Research-grade bimanual arms on your desk. The R1-A takes the arms, torso, and head of Unitree's R1 humanoid, drops the legs, and puts a bimanual teleoperation station on a desk.
What This Is — and Isn't
The R1-A is not a humanoid robot. It's manipulation hardware for the robot-learning era: a matched pair of arms with a shared torso, waist joint, and 2-DOF sensor head, engineered for one job — collecting and executing bimanual manipulation at a price a single grant line can cover.
If you've been pricing out an ALOHA-style rig, a pair of research cobot arms, or a bimanual teleoperation setup for imitation learning, this is that category. The difference is the form factor: instead of two independent arms bolted to a frame, you get an integrated upper body with humanoid kinematics — the same arm hardware that rides on Unitree's legged R1. Demonstration data you collect on the desktop maps directly to the walking version, which matters if your lab's roadmap ends in a mobile humanoid rather than a benchtop cell.
Every unit ships with dual-hand teleoperation controllers as standard — you're collecting bimanual demonstration data out of the box. Secondary development is fully supported with development manuals and robot interfaces, wrist cameras are optional, and hands are chosen separately from an eight-option catalog that runs from parallel grippers to tactile dexterous hands, priced per hand on your quote.
The Four R1-A Models
Unitree's own store, checked October 5, 2026, without hands. Two fixed desktop-mount models, two wheeled. Only the R1-A5 shows a price there, and it is marked unavailable; the other three show none. No dealer we link to lists an A-series model with checkout, so every order is quote-routed and built to order: ask for the current price and production time.
| Model | Form Factor | Arms | Weight | Sensing | Price (no hands) | |
|---|---|---|---|---|---|---|
| R1-A5 | Fixed desktop mount | 2× 5-DOF · 420 mm reach | ~11 kg | Head stereo camera | $4,290 Unitree list price, unavailable Oct 5, 2026 | Request Quote |
| R1-A7 | Fixed desktop mount | 2× 7-DOF · 555 mm reach | ~13 kg | Head stereo camera | Quote | Request Quote |
| R1-A5-D | Wheeled lift-column chassis | 2× 5-DOF · 420 mm reach | ~30 kg | MID360 LiDAR + stereo camera | Quote | Request Quote |
| R1-A7-D | Wheeled lift-column chassis | 2× 7-DOF · 555 mm reach | ~32 kg | MID360 LiDAR + stereo camera | Quote | Request Quote |
Total DOF including waist and head: A5 = 13 · A7 = 17 · A5-D = 16 · A7-D = 20 (the -D chassis adds a lift pillar and 2-DOF wheeled base). Factory "Smart" bundles add a built-in 40 TOPS compute module plus your hand choice; "Ultimate" 100 TOPS bundles are for the wheeled chassis. Both are priced on request.
R1-A vs. Established Bimanual Data-Collection Rigs
Checked October 5, 2026. This is the honest picture: each platform wins somewhere.
| Platform | Configuration | Price | Per-Arm Payload | Teleop Method | Availability |
|---|---|---|---|---|---|
| Unitree R1-A5 | Integrated dual 5-DOF torso | $4,290 list, unavailable | ~2 kg | Dual-hand controllers (included) | Built to order, quote |
| Unitree R1-A7 | Integrated dual 7-DOF torso | Quote | ~2 kg | Dual-hand controllers (included) | Built to order, quote |
| ALOHA Stationary V2 (Trossen) | 4-arm leader-follower kit | Discontinued | ~0.75 kg class | Physical leader arms | Discontinued; successor kits sold as Trossen AI |
| LeRobot SO-101 ×2 sets (DIY) | Dual 6-DOF hobby-servo arms | Hobby budget | Grams-class | Leader-follower | DIY kits, self-assembled |
| AgileX Cobot Magic | Mobile-ALOHA class: 4 arms + AGV base | Quote (tens of thousands) | ~1.5 kg | Physical leader arms | Quote-based |
The trade-offs, plainly: ALOHA-style rigs give you kinesthetic teaching — you puppet follower arms through physical leader arms, which many imitation-learning pipelines were literally designed around — and the ALOHA design has mature LeRobot integration (Trossen discontinued the Stationary kit itself and now sells successor kits as Trossen AI). The R1-A gives you an integrated humanoid-format upper body, teleoperated with included handheld controllers, with roughly double the per-arm payload of ViperX-class followers and a direct data path to Unitree's legged humanoids. The SO-101 route is unbeatable for learning the tooling on a hobby budget, but hobby servos won't survive serious payload or duty cycles. If your bottleneck is budget per bimanual workstation, outfitting a course or scaling a data-collection floor, get a dated R1-A quote and compare it per station.
Who Should Buy One
| You are… | Get this | Why |
|---|---|---|
| A robot-learning lab collecting bimanual demonstration data | R1-A5, several of them | Cheapest credible 2 kg-class bimanual station; controllers included, so every unit collects data on day one |
| A manipulation researcher who needs reach and wrist dexterity | R1-A7 | Two extra DOF per arm and 135 mm more reach: the 7-DOF kinematics handle constrained-workspace tasks the 5-DOF can't |
| Studying mobile manipulation without bipedal complexity | R1-A5-D / A7-D | Wheeled chassis with lift column (0.68–1.32 m working height), MID360 LiDAR, and a 1.5-hour swappable battery |
| Teaching a manipulation course | R1-A5 fleet | Per-seat cost near hobbyist territory with hardware that survives student duty cycles |
| Building toward a humanoid deployment | R1-A now, R1 later | Same arm hardware as the legged R1 — your demonstration data and manipulation stack carry over |
Hands: Eight Options, Priced on Your Quote
No R1-A includes hands — you choose per hand from the same catalog as the full R1. This is where the platform quietly becomes whatever you need it to be: a two-gripper pick-and-place station or a tactile five-finger dexterity rig.
| Hand Option | Type | Price | Best For |
|---|---|---|---|
| Dex1-1 Standard / Advanced (+RGB cam) | Parallel gripper, 485 interface | On quote | Cheapest manipulation entry; pick-and-place teleop data at scale |
| Tendon-cable hand | 5-finger, cable-driven, 2 DOF / 10 joints | On quote | Clean wiring-free design for demos and long duty cycles |
| LinkerBot O6 (± tactile) | 5-finger, 6 DOF / 11 joints, 70 N grip | On quote | Budget five-finger work, with a tactile option |
| BrainCo Revo 2 (± tactile) | Bionic 5-finger, 50 N grip, 0.1° repeatability | On quote | Proven bionic platform; tactile adds pressure, friction, direction, proximity sensing |
| Dex3-1 (± tactile) | Force-controlled 3-finger, 7 DOF, 33 tactile sensors | On quote | Force-control research; highest per-hand active DOF in the catalog |
Hands are priced per single hand on your quote, with required cabling and camera mounts included where noted; most buyers order two. Wrist cameras and compute expansion modules (40 TOPS / 100 TOPS) are optional across the line.
The Wheeled -D Chassis: Mobility Without Legs
The R1-A5-D and R1-A7-D mount the same dual-arm torso on a wheeled base with a motorized lift column. Collapsed, the unit stands 683 mm; elevated, the head reaches 1,323 mm — tabletop to countertop working heights without any of the control complexity (or fall risk) of a bipedal platform.
The chassis carries a removable lithium battery (~1.5 hours of runtime) and an external supply, plus a MID360 LiDAR alongside the head's stereo camera — the sensing package mobile-manipulation research actually needs. Compute expands with optional 40 or 100 TOPS modules, and the factory Ultimate bundles (100 TOPS built in) are exclusive to this chassis.
Unitree's store showed no price for either wheeled model on October 5, 2026, so ask for a dated quote.
A5 or A7?
The A5's 5-DOF arms handle the overwhelming majority of tabletop demonstration tasks — pick, place, stack, sort, hand-to-hand transfer. If you're buying stations for data collection volume, buy A5s and spend the difference on hands.
The A7's 7-DOF arms add redundant kinematics: the elbow can move while the end effector holds pose, which is what lets an arm work around obstacles, reach into containers, and maintain natural approach angles in cluttered scenes. Combined with 555 mm of reach (vs. 420 mm) and a longer 835 mm body, the A7 is the pick for manipulation research — anything where the arm's null space is part of the problem. For a single research station, most labs should take it; price both on the same quote.

Our Role
BotInfo.ai is an independent procurement gateway. We verify manufacturer and dealer pricing directly, date it (R1-A prices on this page were checked on Unitree's store on October 5, 2026; hands are priced on your quote), and route buyers to vetted fulfillment channels that handle purchase orders, institutional billing, and international shipping. We're compensated through fulfillment partnerships, never by marking up hardware — the prices above are the prices.
Verdict
The R1-A does one thing that matters enormously right now: it brings a credible bimanual data-collection station down to a single-grant-line purchase (the R1-A5 lists at $4,290 on Unitree's store, unavailable on October 5, 2026). For robot-learning groups, that changes the unit of planning from "the rig" to "the fleet." Buy the A5 for data-collection volume, the A7 for manipulation research where kinematic redundancy earns its keep, and a -D chassis when the task list includes moving between workstations. Budget hands separately: most stations need two, from parallel grippers to tactile dexterous hands.
Two honest caveats. First, every R1-A is built to order: get the production time in writing on your quote and plan around it, especially against grant deadlines. Second, if your work needs locomotion, the R1-A isn't a shortcut: the full bipedal Unitree R1 starts at $8,990 for the R1 Basic from a US dealer (cart check, October 5, 2026; the R1 Air is quote-only on BotInfo), and the G1-D offers a heavier wheeled dual-arm platform in the G1 family. For everything on a tabletop, though, this is the price-performance line to beat in 2026.
