RoboParty RP1 open-source humanoid robot offers up to 30 DoF, RK3588 and Jetson Orin NX

RoboParty's RP1 (ROBOTO 01) targets robotics researchers and embodied AI developers with a full-stack open hardware platform. The standard model provides 24 active DoF while the Pro variant adds arm and head articulation for 30 DoF, plus an Allwinner A733 co-processor and Jetson Orin NX module. The design emphasizes modularity through interchangeable heads, optional dexterous hands with CAN-FD communication, and hot-swappable dual batteries.

RP1 hardware architecture and compute layout

• Main compute: Rockchip RK3588 (6 TOPS NPU, 8GB LPDDR4x, 32GB eMMC) handles AI inference, vision, speech, and interaction
• Pro add-on: Allwinner A733 plus NVIDIA Jetson Orin NX (16GB) development module for additional AI workloads
• Real-time control: Separate 480MHz MCU manages motion scheduling, power sequencing, and three-channel emergency-stop functions
• Joint actuators: In-house ROMOMO modules with two-stage planetary gear reductions; 100mm-diameter variant delivers 160 N·m peak torque
• Per-joint intelligence: Each ROMOMO module runs local current, velocity, and position control loops via built-in driver
• Power architecture: 48V main lithium battery plus 30V auxiliary battery enables hot-swapping without shutdown; 10Ah total capacity, ~3 hours runtime, 140W USB-C fast charging
• RP Hand: 6 actively controlled axes, 11 mechanical DoF total (5 passive/coupled), worm-gear transmission, CAN-FD bus, ~379g weight, optional tactile sensing

Why it matters

The RP1 enters a growing field of open humanoid platforms aimed at lowering barriers for embodied AI research, with its full-stack openness and modular head/hand options allowing researchers to swap perception and manipulation capabilities without changing the base platform.
