Galaxea A1 Robotic Arm (A1)

Ask a humanoid robot to hand you a cup, and the hand gets the credit, but it is the arm that decided where the hand could go. The Galaxea A1 Robotic Arm (A1) is that part of the story, sold as a single, lightweight, force-controlled arm with six degrees of freedom and a maximum reach of 700 mm. For teams that want the reaching and handling skill of a humanoid platform without buying the whole body, it is a sensible place to begin.

The Galaxea A1 Robotic Arm (A1) is available through this page, by quotation.

Background

GALAXEA and the arm behind its humanoids

GALAXEA builds robots for manipulation work, and the A1 is one of its core building blocks. It is a lightweight, force-controlled robotic arm engineered for remarkable agility and confident payload handling. That description tells you where the design effort went: toward an arm that moves freely and stays composed while it works, rather than toward sheer size.

The A1 is not only sold on its own. The Galaxea R1 humanoid is built around two Galaxea A1 robot arms and two Galaxea G1 grippers. In other words, the arm you can request here is the same family of arm that GALAXEA relies on for its own two-armed platform. For a buyer, that lineage is a useful signal: the A1 was shaped by the needs of a robot that has to do real tasks with both hands.

The A1 also belongs to a small family. The sources name the versions A1, A1X, A1Z and A1XY. This page covers the A1 only, and every figure below belongs to the A1. If you are weighing a sibling, the Galaxea A1 XY Robotic Arm (A1 XY) has its own page.

Positioning and key technology

Two ideas define the A1: force control and high dynamics. Force control means the arm is built to manage the interaction between itself and the objects it touches, which matters whenever a task involves contact rather than free motion. High dynamics means superior agility with full-stroke motion across all six joints and a maximum reach of 700 mm.

Six degrees of freedom is the figure that lets an arm place a tool or gripper at a position and also choose its orientation. Together with a 700 mm reach, that gives the A1 a working envelope suited to tabletop and workcell tasks, the kind of space where a person would normally use one arm. It runs at a rated voltage of 48 V, a figure worth noting early when you plan the power supply for a bench or a mobile base.

Within the wider catalog, the A1 sits among our Robot Arms and is also relevant to buyers browsing cobots, since both groups look for arms that can work close to people and objects.

Technical Specifications

The manufacturer has not published the IP rating, the operating temperature, the package contents, the software and SDK support, the operating noise level or the control interface protocol; they are confirmed at quotation.

What makes the A1 different from a general-purpose arm?

Many arms are described by how much they can move. The A1 is described by how well it can move and how it can handle what it touches. Its description stresses agility and confident payload handling, and the pairing of force control with full-stroke motion in all six joints points to an arm made for dexterous work rather than for repeating one fixed path.

The second difference is its role. The A1 is the arm that GALAXEA places on its own humanoid, two to a robot. An arm designed to serve as one half of a pair has to be light enough to be carried by a mobile body and capable enough to share a task with its twin. That is a different design brief from a stand-alone arm bolted to a table, and it explains the emphasis on a lightweight build.

The third difference is what we do not claim. Some details that buyers consider essential, such as the IP rating or the control interface protocol, are listed above as unpublished. If one of them decides your purchase, raise it in your quotation request.

How does the A1 relate to the Galaxea R1 humanoid?

The Galaxea R1 features two Galaxea A1 robot arms and two Galaxea G1 grippers. This is the clearest fact connecting the arm to the larger platform, and it shapes how you might choose between them.

If your goal is a complete wheeled humanoid for manipulation research or demonstration, look at the platform pages instead: the Galaxea R1 Wheeled Humanoid Robot, the Galaxea R1 Lite Wheeled Humanoid Robot (R1 Lite) and the Galaxea R1 Pro Wheeled Humanoid Robot (R1 Pro). If your goal is the arm itself, for a bench, a workcell or your own mobile base, the A1 is the right page. We do not state which arm versions fit the R1 Lite or R1 Pro; ask us if that matters to you.

Who is the Galaxea A1 Robotic Arm (A1) for?

University and research laboratories are the first segment. A six-axis arm with force control gives students and researchers a platform for studying manipulation, contact-rich tasks and the behavior of arms working alongside other equipment. The 48 V rated voltage and the 700 mm reach make it straightforward to plan a bench setup.

Robotics developers and integrators are the second segment. If you are building a mobile manipulator or a two-armed station of your own, an arm that GALAXEA itself uses in pairs is a credible starting point. Interface details such as the control protocol are not listed above, so raise them in your request.

Training centers and technical schools are the third. An arm with six joints teaches the full range of motion that industrial work demands, in a form that is lighter than most production machines.

Buyers who want the complete humanoid should look to the R1 family linked above, and buyers who need a different arm variant should compare the A1 XY page linked earlier before deciding.

What is the Galaxea A1 Robotic Arm (A1) used for?

1. Manipulation research. Studying how an arm reaches, grasps and places objects across six degrees of freedom.
2. Contact-driven tasks. Work in which the arm touches or presses on an object and force control matters.
3. Dual-arm builds. Pairing two arms on a mobile or fixed body, the way the Galaxea R1 does.
4. Teaching and training. Showing students how six joints combine to position and orient a tool.
5. Prototyping workcells. Testing a pick, place or handling idea within a 700 mm reach before committing to a larger system.
6. Demonstrations. Showing visitors and customers what a lightweight, agile arm can do in a compact space.

Summary

The A1 is the arm behind the hand: lightweight, force-controlled, six-jointed and able to reach 700 mm on a rated 48 V supply. It is the same kind of arm that GALAXEA fits in pairs to its Galaxea R1, now available on its own for labs, developers and trainers. Some details remain unpublished, and we will not guess them for you. When you are ready to compare the A1 with your project, this page is the starting point.
