Unitree R1-A5 Dual-Arm Humanoid Robot — Unitree
Overview

What is the Unitree R1-A5 Dual-Arm Humanoid Robot?

The Unitree R1-A5 is a fixed-base dual-arm humanoid: 13 degrees of freedom (5 per arm, 1 waist, 2 head), roughly 11 kg, with a 420 mm arm reach and about 2 kg payload per arm. The R1-A5-D variant adds a wheeled chassis and a lifting column, taking it to 16 degrees of freedom.

Every R1-A5 configuration is the same torso paired with one of eight dexterous hands and one of two compute tiers.

RobotLAB supplies the full Unitree humanoid range in the United States, with 26 R1-A5 configurations currently listed, from $7,200 to $35,200. Every configuration below is quoted, supported and serviced from the US.

How it works

Unitree R1-A5 Dual-Arm Humanoid Robot in detail

Choosing a configuration

The table below is the honest version of the spec sheet: it shows only what actually differs between configurations, so you can see what the extra money buys. Shared platform specifications are listed separately — they apply to every unit in the range.

Typical buyers are manipulation research, bench automation and teleoperation work. If you are not sure which build fits your work, ask us: we configure these for US customers every week and will tell you when a cheaper configuration does the job.

See the rest of the range on our humanoid robots page, or browse everything we carry from Unitree.

Most configurations differ only by the hand fitted. If you want to compare end effectors on their own, see Unitree humanoid hands and grippers.
