Unitree R1-A5 Dual-Arm Robot (Desk-Mount & Mobile Base)

OverviewThe Unitree R1-A5 is a dual-arm manipulation robot built for research, data collection, and embodied-AI development: two 5-DoF arms, a rotating waist, and a 2-DoF sensor head on a compact torso. Choose the desk-mount R1-A5 for benchtop manipulation work, or the R1-A5-D, which puts the same torso on a wheeled mobile base with a powered lifting column and MID360 LiDAR for mobile manipulation. Every configuration is open for secondary development. Manual-Verified Specifications (Unitree 2026.7 price list) Spec R1-A5 (desk-mount) R1-A5-D (mobile base) Dimensions 700 × 357 × 190 mm (head to hanging arm tip) 683 × 520 × 440 mm collapsed; 1,323 mm elevated Weight ~11 kg ~30 kg Degrees of freedom 13 (5 × 2 arms + 1 waist + 2 head) 16 (adds lifting column + 2 base) Arm payload ~2 kg per arm (varies with posture) Arm length (forearm + upper arm) 420 mm Sensing Stereo camera on head MID360 LiDAR + stereo camera Compute 8-core CPU (body) + 8-core CPU with 10 TOPS (head); Smart configs add built-in 40 TOPS Orin Nano; Ultimate configs (A5-D only) add 100 TOPS Orin NX Power External supply standard; optional upper-body battery (~1.5 h) Removable chassis battery standard (~1.5 h) + external supply Joint design Crossed-roller + double-row ball bearings, hollow internal cabling, dual + single encoders, localized air cooling Audio 4-array microphones Waist / head range Waist Y ±150°; head Y ±115°, P ±36° SDK Yes, full secondary development support Warranty 12 months, serviced via Unitree's authorized US distribution Choosing a Configuration No Hands: bring your own end effectors; ideal if you already have grippers or are developing custom hands. Smart (40 TOPS): built-in Orin Nano compute plus your choice of hands: Dex1-1 V2 grippers (A), Dex3-1 three-finger force-controlled hands (B/C), BrainCo Revo 2 bionic hands (D/E), LinkerBot O6 six-DoF hands (F/G), or tendon-driven dexterous hands (H). Tactile versions add fingertip sensing for contact-rich manipulation research. Ultimate (100 TOPS, R1-A5-D only): Orin NX compute for onboard VLA/policy inference with the same hand options. Need 7-DoF arms with longer reach? See the Unitree R1-A7. Who It's ForUniversity manipulation and embodied-AI labs, imitation-learning and teleoperation data collection, humanoid research programs that need arms-and-hands without legs, and industrial R&D teams prototyping bimanual tasks. Pairs naturally with teleoperation rigs for demonstration data. Quotes & Purchase OrdersMost R1-A5 configurations are research purchases. Request a formal quote for institutional procurement; we support university and government purchase processes. Frequently Asked QuestionsWhich hand option should I choose?Dex1-1 V2 grippers (configuration A) are the most economical for pick-and-place and imitation-learning data collection. Dex3-1 three-finger force-controlled hands (B/C) suit dexterous manipulation research, with the tactile version adding fingertip sensing for contact-rich tasks. BrainCo Revo 2 (D/E) and LinkerBot O6 (F/G) offer humanlike bionic form factors, and tendon-driven hands (H) trade ruggedness for high dexterity. Tell us your research goals and we will match the configuration. Desk-mount or mobile base: which do I need?The desk-mount R1-A5 is for fixed benchtop workcells and costs less. The R1-A5-D adds a wheeled chassis with a powered lifting column and MID360 LiDAR, so the same torso can navigate a lab or facility and work at varying heights. If your tasks stay on one bench, the desk-mount is enough. Can I program it?Yes. Every R1-A5 configuration supports secondary development with development manuals and ecosystem support, and Smart and Ultimate configurations include onboard NVIDIA compute (40 or 100 TOPS) for running your own perception and policy models. How long does delivery take?Lead times vary by configuration and factory availability. We confirm the current lead time when you order or request a quote and keep you updated through delivery. What warranty comes with it?Every unit includes a 12-month manufacturer warranty serviced through Unitree's authorized US distribution, with US-based repair. Ask about extended coverage when you request a quote. Do you accept purchase orders?Yes. We support university, government, and enterprise procurement with formal quotes, vendor registration, W-9 documentation, and purchase orders for verified institutions.
