Unitree G1 vs Unitree R1
Last reviewed: 22 October 2026
In short: choose Unitree G1 if you want the more mature, more sensor-equipped humanoid platform. It's taller (1320 mm) and more robust (≈ 35 kg), has a depth camera + 3D LiDAR for mapping and navigation, an 8-core high-performance CPU, a 9000 mAh smart battery (≈ 2 h battery life) and a knee with 90 N·m of torque. Choose Unitree R1 if you want a lighter, more agile humanoid. It's shorter (1230 mm) and lighter (≈ 29 kg), has more joints (26 motors, with 2 waist and 2 head degrees of freedom), an ultra-wide-angle binocular camera, an on-board GPU compute module and a detachable battery for hot-swapping. In short: G1 is the stable, LiDAR-equipped platform for research and navigation, while R1 is the lightweight humanoid with more joint mobility and an on-board GPU.

Both are bipedal Unitree humanoid platforms, with 6-DoF legs, 5-DoF arms and a similar arm payload (≈ 2 kg). The main difference is that G1 is taller, heavier and has 3D LiDAR, while R1 is lighter, has more joints (26), binocular vision + GPU and a detachable battery. Both G1 and R1 also have EDU versions (secondary development / SDK).
Frequently asked questions
What's the main difference between Unitree G1 and R1?
G1 is taller (1320 mm) and heavier (≈ 35 kg), with a depth camera + 3D LiDAR and a 9000 mAh smart battery (≈ 2 h). R1 is lighter (≈ 29 kg) and shorter (1230 mm), with more joints (26 motors), binocular vision, an on-board GPU compute module and a detachable battery.
Which robot has better perception and navigation?
For LiDAR-based mapping and navigation, choose G1: it has a depth camera + 3D LiDAR. R1 uses an ultra-wide-angle binocular camera and a GPU compute module, focused on visual perception.
Which robot has more degrees of freedom?
R1, with 26 joint motors (including 2 waist and 2 head degrees of freedom), versus 23 on the standard G1. Both have 6 degrees of freedom per leg and 5 per arm.
Do they also have EDU versions?
Yes. Both G1 and R1 have EDU variants with secondary development (SDK) and extra options. See also our Unitree G1 vs G1 EDU comparison for the differences between the standard and research versions.
Do they have a public price?
No, both are quote-based. IRIS Robotics sells Unitree robots in Romania and provides pricing, configuration, integration, training and technical support.
Is there also a Unitree G1+?
Yes. Unitree G1+ keeps the compact format of G1 and adds a mobile neck (2 degrees of freedom), binocular vision and tactile sensors on the head, with 25 degrees of freedom in total. Details and differences are on the Unitree G1+ page.
