RoboParty Roboto Origin

Overview

Fully open-source, build-it-yourself bipedal humanoid from Shanghai RoboParty: 1.25 m tall, 34 kg, 23 degrees of freedom (6 per leg, 5 per arm, 1 waist), CNC-machined structure with parallel ankles and human-like offset joints, 48 V / 15 Ah battery, about 3 m/s top speed and more than 2 h of runtime. Runs ROS 2 with an RDK X5 main controller, Wi-Fi 6 and Bluetooth 5.2; Intel RealSense D435i and a 3D LiDAR are optional. Mechanical, electronic, control and simulation files are published openly (core software GPL v3, hardware descriptions under CERN-OHL-W 2.0 and CC-BY-SA 4.0).

Key facts

• Official spec page (roboparty.com/products/RPO, Chinese, fetched 2026-10-17): height 1.25 m, weight 34 kg, thigh 250 mm, shank 300 mm, arm 440 mm; 23 DoF (arm 5: shoulder 3, elbow 1, wrist 1; leg 6: hip 3, knee 1, ankle 2; waist 1); speed 3 m/s; arm joint peak torque 27 N.m, leg joint peak torque 120 N.m; battery 48 V, 15 Ah; runtime 'over 2 hours' (varies with load); Intel D435i and 3D LiDAR optional; ROS 2, Wi-Fi 6, Bluetooth 5.2, OTA upgrade, low-level control SDK and manual control; CNC machining, parallel ankle, human-like offset joints.
• battery_wh 720 is derived from 48 V x 15 Ah, not a published Wh figure; battery_hours 2 is the lower bound of the official 'over 2 h'. max_speed_kmh 10.8 is converted from 3 m/s.
• Sources per field: official RoboParty page/docs: compute RDK X5 (D-Robotics, named in the flashing docs), dimensions, DoF, speed, torque, battery, ROS 2, Wi-Fi 6. humanoid.guide (third party, fetched 2026-10-17): 10 TOPS, DAMIAO motors, Ubuntu 22.04. GitHub README badges and repos (roboparty/roboto_origin): Isaac Lab / rsl_rl, Python 3.10, C++17, Ubuntu-based Linux. IMU listed in the dealer kit contents. humanoid.guide also lists 5 kg 'strength', which is unlabelled, so payload_kg is null.
• Open source: the official GitHub roboto_origin README states GPL v3 for the core code; rpo_description is CERN-OHL-W-2.0 and rpo_hardware SPDX CC-BY-SA-4.0 (fetched 2026-10-17). The README says the robot can be assembled from Taobao-sourced parts and prototyping services, and that RoboParty was founded 2025-02-21 with the prototype finished within four months.
• Sold as a DIY kit (the dealer lists a V2 kit, currently backordered); the official site offers no assembled units and no price. humanoid.guide lists availability as prototype. Catalog status is 'limited' because the only purchase route found is a backordered dealer kit. The kit excludes the battery: battery_wh / battery_hours describe the official 48 V / 15 Ah pack; the official page's 34 kg weight carries no stated battery basis.
• Distinct from RoboParty's other products ROBOTO 01 (RP1) and RP Hand shown in the site navigation; those are not catalogued here.
• Image: official RoboParty render from the roboto_origin GitHub repository (assets/1280X1280.PNG, 1280 x 1280 source, fetched 2026-10-17), dark studio background, cropped and padded to 800 x 534; the 'ROBO PARTY' wordmark that sat beside the robot in the original was retouched out with a background gradient fill. Only the small mark on the robot's chest remains.
• year_announced is null: no source states an announcement date (RoboParty was founded 2025-02-21 per its GitHub README).
