Galaxea R1 Wheeled Humanoid Robot

Galaxea R1 Wheeled Humanoid Robot (R1 Series)

Introduction / Overview

The Galaxea R1 Wheeled Humanoid Robot is a dual-arm, mobile manipulation platform designed to combine human-scale reach, bimanual manipulation, and robot navigation in a single wheeled system. The R1 is commonly described as a wheeled humanoid because it adopts an upper-body humanoid form factor—torso plus two arms—mounted on a maneuverable mobile base rather than bipedal legs. This architecture prioritizes stability, continuous operation, and practical deployment in labs and indoor environments while retaining the dexterity needed for real-world manipulation tasks.

In official product documentation, the R1 is presented as a full-size dual-arm humanoid robot with a vertical operating range up to ~2 meters and a horizontal operating radius around ~700 mm, targeting applications that require broad workspace coverage, mobile pick-and-place capability, and flexible interaction with objects at different heights—including floor-level retrieval and high-shelf access.

Design and Features

Wheeled humanoid architecture (mobile base + humanoid upper body)

Unlike traditional industrial manipulators fixed to a bench or pedestal, the R1 is designed for mobile manipulation: it can reposition itself and then execute manipulation tasks using its arms. Galaxea’s published overview describes the R1 as combining two Galaxea A1 robot arms, two G1 grippers, a 4-DoF torso, and a three-wheel steering vector chassis, enabling both reach expansion and agile indoor mobility.

This configuration reflects a growing industry trend: wheeled humanoids and mobile manipulators often achieve higher real-world task throughput than bipedal robots by avoiding balance constraints while still maintaining “human-like” manipulation posture and reach.

Dual-arm manipulation with torso articulation

The R1 concept emphasizes bimanual coordination—two arms working together—supported by a torso that adds extra degrees of freedom for workspace extension and ergonomic posture changes. In research literature referencing the platform, the R1 is described with two 6-DoF arms mounted on a 4-DoF torso, a structure well-suited to tasks like opening containers, stabilizing objects with one gripper while manipulating with the other, and executing coordinated two-hand actions.

End-effectors: grippers and dexterity options

Product materials commonly reference parallel grippers as the default end-effector configuration, optimized for reliable grasping across many object types. Some third-party listings and announcements mention optional configurations that can include more dexterous hands depending on the model variant and accessory selection.

“R1 Series” model lineup (R1 Pro, R1, R1 Lite)

Public-facing sources describe the R1 ecosystem as a series with multiple variants, typically including R1 Pro, R1, and R1 Lite, with differences in degrees of freedom, arm configuration, sensing, and compute.

Technology and Specifications

Important note on specifications:
The R1 name is used across multiple variants (Pro / standard / Lite), and published specs can differ by configuration and distributor. The figures below summarize commonly cited specifications from official documentation and widely referenced third-party spec listings.

Core workspace and kinematics

Official documentation highlights the R1’s work envelope as:

• Vertical operating range: up to ~2 m

• Horizontal operating radius: ~700 mm

This human-scale workspace is a defining feature: it allows the robot to interact with benches, carts, shelves, and floor-level objects with fewer base repositioning steps.

Arms, torso, and degrees of freedom

In the official product overview, the R1 is equipped with:

• Two Galaxea A1 robot arms (commonly described as 6-DoF each)

• A 4-DoF torso

Third-party listings for the R1 Pro commonly report a 26-DoF embodiment (overall), reflecting the sum of torso, dual arms, and other articulated joints depending on the exact build.

Mobility: vector steering / omnidirectional drive

The official overview describes a three-wheel steering vector chassis, emphasizing maneuverability in indoor operational environments.
In research describing the R1 Lite platform, the base is characterized as a vector-drive omnidirectional base, which is particularly useful for tight-space repositioning during manipulation tasks.

Sensors and perception stack

Sensor configurations vary, but commonly referenced options include:

• Head binocular RGB camera

• Multiple chassis monocular cameras

• 360° LiDAR as standard on some configurations

• Optional wrist cameras for close-range manipulation perception

This multi-camera + LiDAR approach supports navigation and obstacle awareness while also enabling vision-guided grasping and hand-eye coordination tasks.
