Industrial Applications

KUAVO 4.1 is a 155 cm/50 kg documented generation, distinct from the filing’s 152 cm/51 kg KUAVO 4 and 166 cm/55 kg 4Pro. Its manual has 28-body versus 30 table DOF ambiguity; no single total assigned.

This editorial assessment concerns industrial buyer readiness. It is not an independent performance test.

SDK and Integration

Exact historical controller, SDK access and maintained simulation support not verified.

API typeROS controller topics/services and Kuavo Python SDK
LanguagesC++ controller source, Python SDK
ROS supportROS1 package explicitly documented; this Python package excludes ROS2. Confirm delivered controller branch.
SimulationMuJoCo launch examples and Docker controller simulation; robot description and ROBOT_VERSION must match.
Offline operationLocal controller/simulation examples exist; optional cloud speech, VLA and model services need separate dependency review.
TeleoperationVR/remote-controller and data-collection workflows documented in ecosystem; edition/hardware compatibility must be confirmed.
Software updatesRepository/package releases; version-match controller, SDK and calibration. Firmware support period unknown.
DocumentationOpen documentation

    Official version-specific product chapter inspected, including mechanical, battery, sensor, compute, end-effector and emergency-stop tables. Upper-level prospectus and family marketing may use different counting, configuration or endurance conditions. Chapter diagrams are manufacturer illustrations.

  • Kuavo Humanoid Python SDK ↗ Leju Robotics · Accessed Nov 2, 2026

    Manufacturer-maintained package documents Python ROS1 SDK; expressly excludes ROS2 in this package. State/motion, hands, head, torso and MuJoCo examples; branches and robot version must match. This package is not the current Roban 2.2 C++ DDS SDK.

  • KUAVO ROS open-source controller repository ↗ Leju Robotics · Accessed Nov 2, 2026

    Manufacturer README inspected: hardware-specific ROBOT_VERSION, per-unit mass calibration, catkin and Docker simulation; model matching matters. MIT source repository includes external dependencies and prebuilt hardware components; no blanket hardware-source or firmware openness.
