A Pittsburgh-based company has unveiled its powerful open-source humanoid robot. The robot, called RP1 (ROBOTO 01), was publicly unveiled at IROS 2026, marking its global debut.
The company positions RP1 as the world’s first high-performance, full-stack, open source bipedal humanoid robot. RP1 is aimed at researchers, educators, robotics developers and embodied AI teams with the goal of providing a humanoid robotics system that can be used, modified, trained and continuously expanded in real-world development workflows.
Visitors could apply external perturbations directly to the robot
“Humanoid robots should not be closed systems that only a small number of teams can build while everyone else can do little more than watch,” said Yi Huang, founder of RoboParty.
“We want RP1 to become an open foundation that developers can access, modify, train and continually improve. Full-stack open source has been our technical direction since the RPO project.”
Visitors could apply external perturbations directly to the robot
At RoboParty’s IROS booth, the “Kick Me” interactive demonstration was one of the most direct ways for visitors to experience RP1’s capabilities. During the demonstration, visitors were able to apply external perturbations directly to the robot. When RP1 was pushed or kicked, it quickly adjusted its posture and regained its balance. Unlike demonstrations that were based only on predefined movements, this open interaction allowed visitors to observe the robot’s dynamic stability and control performance under external disturbances, according to a press release.
The repeated high-intensity interactions also enabled a direct system-level test of the robot’s body performance and robustness.
RP1’s dynamic motion and jamming capabilities at IROS were supported by PartyOS, RoboParty’s open research and development base for humanoid robotics that integrates the UFO framework.
The robot is intended to provide a powerful humanoid platform for dynamic movements
The company also highlighted that the RP1 is designed to provide a powerful humanoid platform for dynamic movement, embodied AI model training, validation and deployment, data collection and continuous development.
RoboParty also revealed that the RP1 delivers a maximum joint torque of up to 160Nm. From the self-developed Romomo actuator modules and mechanical structure to the real-time motion control system, RP1 is designed to meet the needs of dynamic motion, troubleshooting and long-term development experiments.
The company also highlighted that during the “Kick Me” interaction, visitors directly applied external interference while RP1 adjusted his posture and regained his balance. The robot also demonstrated continuous motion, disruption recovery, and fall recovery. These behaviors reflected not only the algorithmic performance but also the coordination of the robot body, actuator modules, and motion control system.
The company announced that RP1 builds on RoboParty’s broader full-stack open source roadmap. RoboParty started with RPO, its fully open source bipedal humanoid robotics project. Through the development and acceptance of RPO in the community, RoboParty expanded its technical capabilities to include core actuators, robotic bodies, motion control, dexterous manipulation, and robotics software systems.
