RoboParty announces RP1 open-source humanoid, with no price or sale date

RoboParty publicly unveiled its RP1 humanoid at IROS on 28 September 2026. The company plans broader hardware and software releases, followed by a mass-production programme later in the fourth quarter of 2026. RP1 is not currently listed for sale. The announcement gives no price or delivery date.

What changed for buyers

RoboParty’s announcement, published on 3 October 2026, introduced RP1 as a bipedal research and development platform. The intended users include researchers, educators, robotics developers and embodied AI teams.

The announcement says a mass-production programme will follow later in the fourth quarter of 2026. It does not say when buyers will be able to place an order or receive a robot. It also does not identify markets, production volumes or sales channels.

Electronics For You reported on 6 October 2026 that RoboParty plans to publish more details about the RP1 open-source roadmap during October 2026. Additional hardware and software releases are planned after that.

The open-source material will be released progressively. Humanoid.guide reported on 6 October 2026 that the announcement does not establish that RP1’s complete hardware and software stack is already available.

What the maker says

RoboParty’s 3 October 2026 announcement gives RP1 a maker-stated peak joint torque of up to 160 N·m. The robot uses the company’s Romomo actuator modules and a real-time motion-control system.

At IROS 2026, RoboParty ran a “Kick Me” demonstration. Visitors pushed and kicked RP1, after which the robot adjusted its posture and recovered its balance. Humanoid.guide said on 6 October 2026 that the available coverage provides no quantified recovery benchmark or independent performance assessment.

RoboParty says PartyOS supports the robot’s control and training systems. PartyOS incorporates UFO, an unsupervised reinforcement-learning framework intended to develop motion policies for skill transitions, disturbance recovery and fall recovery without predefined trajectories. These are maker descriptions of the framework. Published evaluation results are not provided.

The company plans to open more than mechanical design files. Its stated roadmap covers motion-control systems, simulation environments, software development kits, training tools and the PartyOS platform.

The platform behind RP1

Open Source For You reported on 6 October 2026 that RP1 builds on RoboParty’s earlier RPO, or ROBOTO ORIGIN, platform. RPO repositories include hardware files, ROS 2 deployment software, reinforcement-learning workflows, robot models, firmware, navigation tools and XR teleoperation modules.

The same report says the main RPO repository generally uses the GPLv3 licence. Individual modules and third-party components retain their own applicable licences. Licensing terms for the complete RP1 stack have not been published.

Still unconfirmed

• Price and preorder date.
• First delivery date and available markets.
• RP1 height, weight, payload, runtime and walking speed.
• Production volume for the planned fourth-quarter programme.
• The release date and licences for the complete RP1 hardware and software stack.
• Independent measurements of joint torque, balance recovery or other performance.
