    Product Preview:

    DYNAMIXEL-Q and AI Sapiens K1 information is provided as an early product and platform preview. Specifications, software behavior, open-source resources, documentation, model names, and availability may change without prior notice.

    23 DOF

    Whole-body humanoid motion platform.

    35 kg

    Compact physical AI research platform.

    1366 mm

    Humanoid form factor for real-world development.

    48 V

    DYNAMIXEL-Q actuator system voltage.

    SystemTechnologyEngineering Benefit
    Architecture Quasi-Direct Drive Low-ratio, responsive actuation.
    Motor Frameless BLDC High power density in a compact joint.
    Feedback Dual Encoders Motor- and output-side joint sensing.
    Integration Hollow Shaft Cleaner cable routing and packaging.
    Control Impedance Mode Compliant, torque-aware interaction.
    QDD Smart Actuator Platform

    Built for Real Robot Dynamics

     

    DYNAMIXEL-Q combines low-ratio QDD mechanics, integrated electronics, high-resolution feedback, and torque-aware control in a compact smart actuator. The result is responsive joint motion suited to humanoid locomotion, balance, physical interaction, and whole-body control.

    DYNAMIXEL-Q Actuators Used in K1

    The Q-Series Hardware Behind the Humanoid

     

    AI Sapiens K1 uses two DYNAMIXEL-Q actuator sizes: a compact QC060 model for smaller joints and a higher-capacity QC080 model for larger load paths.

    Robot Software Stack

    From Policy Output to DYNAMIXEL-Q Motion

     

    AI Sapiens K1 connects simulation, policy training, ROS 2 control, and DYNAMIXEL-Q actuation into one development workflow. Motion policies can be trained in simulation, then deployed through the robot software stack to drive real QDD actuators.

    The platform runs on an NVIDIA® Jetson Orin™ NX 16GB module inside the ai_sapiens Docker container, using Cyclo OS, ROS 2 Jazzy, Zenoh RMW, ROS 2 control, and high-speed DYNAMIXEL communication over RS-485.

    Onboard Compute

    NVIDIA® Jetson Orin™ NX 16GB for robot-side control and deployment.

    Containerized Runtime

    ai_sapiens Docker container for repeatable software setup.

    ROS 2 Control

    ROS 2 Jazzy, Zenoh RMW, and DYNAMIXEL hardware interface.

    QDD Actuation

    RS-485 communication to DYNAMIXEL-Q actuators at 6 Mbps.

    AI Sapiens Demonstration

    DYNAMIXEL-Q in a Real Humanoid Platform

     

    AI Sapiens shows the type of motion, control, learning, and real-world robot behavior that DYNAMIXEL-Q is being developed to support.

    Coming Soon

    Get Ready for DYNAMIXEL-Q and AI Sapiens K1

    DYNAMIXEL-Q is being developed for the next generation of Physical AI robots: humanoids, legged systems, dynamic manipulators, and real-world learning platforms. AI Sapiens K1 brings that actuator platform into a complete humanoid development system.
