The demonstration in Pittsburgh offered a stark look at the machine’s capabilities as visitors physically pushed and kicked the robot to test its recovery systems. RP1 maintained its balance using the proprietary UFO training framework, which utilizes unsupervised reinforcement learning to manage skill transitions and fall recovery without relying on rigid, pre-programmed trajectories. This system-level robustness is powered by in-house Romomo actuators, capable of delivering peak joint torque of 160 N•m.
RoboParty Debuts RP1 Humanoid to Democratize Open-Source Robotics
At IROS 2026, RoboParty showcased the RP1, a high-performance bipedal humanoid designed to dismantle the barriers of closed-system robotics. By opening its hardware designs, custom actuator modules, and the PartyOS training framework to the public, the company aims to provide researchers and embodied AI developers with a fully accessible development foundation.

RoboParty founder Yi Huang emphasized that the project seeks to shift the industry away from proprietary silos, allowing the global community to modify, train, and improve the platform collaboratively. The company plans to release its motion-control systems, SDKs, and simulation environments incrementally throughout the remainder of 2026. With a development team hailing from institutions including Stanford, Carnegie Mellon, and Tsinghua University, RoboParty is already coordinating a roadmap that includes broader software releases and a mass-production program slated for the fourth quarter.
