Short answer: ARX lists 21 published projects that were built on its hardware, including π0, π0.5, π0.7, RDT, ViA, Motus and Xiaomi-Robotics-0. Four more public projects, EgoVerse, RoboTwin 2.0, UMI and UVA, name ARX arms in their papers or code. Together they cover foundation models, world models, human-to-robot transfer, reinforcement learning and benchmarks.
How we checked each project
There are two kinds of evidence:
- Named in the project's own material. The paper, project page or code names ARX hardware. Examples: π0's training mixture lists "Bimanual ARX"; Motus ran its real-world experiments on AC-One; ViA thanks ARX for its robot hardware.
- Listed by ARX. The project appears in ARX's list of research built on its platform at arx-x.com, and the project page does not name the hardware.
The research page marks which kind applies to each entry.

What this means if you are choosing hardware
- Reproducibility. If you plan to compare against π0-style or ALOHA-style results, using arms that appear in that work removes one variable.
- Software that others have used. Stanford's arx5-sdk exists because a research lab needed it, and several of the projects above build on it.
- A benchmark path. RoboChallenge runs physical evaluations on Arx5 robots, and RoboTwin 2.0 includes ARX-X5 in simulation.
