"RoboParty RP1 Open-Source Humanoid Debuts"

"RoboParty showed its RP1 biped at IROS 2026 and says it will open more software and hardware later this year."

The RoboParty RP1 open-source humanoid, also called ROBOTO 01, made its public debut at IROS 2026 in Pittsburgh on September 28. The company says the biped follows its ROBOTO ORIGIN project and plans more RP1 hardware and software releases later this year.[1]

2026-01: RoboParty launched the ROBOTO ORIGIN open-source project, according to its October announcement.[1]
2026-09-28: RP1 made its public debut at IROS 2026.[1]
2026-Q4: RoboParty says broader RP1 releases and a mass-production program will follow. It has disclosed no details.[1]

What did RoboParty show at IROS?

At IROS, visitors pushed and kicked RP1 while it recovered its posture, according to RoboParty. This public demo is not a third-party benchmark or safety validation result.[1]

RoboParty founder Yi Huang said the company wants developers to be able to access, modify, train, and improve RP1.[1]

The company says RP1 uses its Romomo actuator modules and a real-time motion-control system, with peak joint torque up to 160 N m. It calls PartyOS the software foundation behind the machine. Those are vendor claims. RoboParty has not provided a data sheet covering mass, payload, battery life, speed, ingress protection, or price.[1]

What does open source mean for RP1?

RoboParty says it plans to release motion-control software, simulation environments, SDKs, training tools, and PartyOS in stages. The key word is "plans." The October announcement does not say which RP1 components are public today or under which licenses.[1]

Its earlier ROBOTO ORIGIN repository offers a reference point. The public project gathers separate hardware, firmware, training, model-description, navigation, and teleoperation repositories. Its README directs contributors to module-level repositories instead of the aggregate project.[2]

The separate deployment repository describes a ROS 2 framework for RPO and Roboto robots, including drivers, inference, controller tools, and deployment scripts. RoboParty licenses its own material under GPL-3.0-only, while submodules and other third-party material keep their own terms.[3]

What remains unverified?

RP1 is a fresh debut, so the current evidence comes from RoboParty's announcement and its existing code repositories. That is enough to report the launch and the company's stated roadmap. It is not enough to judge reliability, safety, production readiness, or real-world task performance. Those need third-party testing or customer deployment evidence.
