HOPEJr

Model: hopejr

HOPEJr is an open-source DIY humanoid robot project from the Hugging Face LeRobot ecosystem and The Robot Studio. The May 2025 unveiling positioned it as a roughly $3,000 full-size humanoid intended to lower the cost of robot-learning hardware, while current official materials show an active developer platform rather than a consumer-ready home assistant. The official HOPEJr repository includes full-body design and URDF assets plus an actively updated arm and dexterous-hand stack, and Hugging Face's LeRobot documentation covers arm/hand calibration, teleoperation, recording, replay, and training workflows. Treat it as experimental research hardware for builders who can assemble, calibrate, and debug an open-source robot.
