DYNAMIXEL-Q / AI Sapiens K1 / Physical AI
DYNAMIXEL-Q
Powers AI Sapiens K1
DYNAMIXEL-Q is ROBOTIS’ QDD actuator platform for dynamic humanoids, contact-rich motion, torque-aware control, and next-generation Physical AI.
The new AI Sapiens K1 demonstrates what DYNAMIXEL-Q is built to enable: a real 23-DOF humanoid platform for locomotion, whole-body control, reinforcement learning, imitation learning, and sim-to-real development.

QDD Smart Actuator Platform
Built for Real Robot Dynamics
Physical AI requires hardware that can move through contact, respond to disturbances, and execute learned behaviors on real machines. DYNAMIXEL-Q combines QDD actuator design, low gear reduction, integrated electronics, high-speed communication, and torque-aware control for robots that need more than simple position movement.
- Quasi-Direct Drive architecture for dynamic humanoid motion
- Low-inertia PMSM actuator design for responsive control
- Low backlash and torque-aware behavior for contact-rich robotics
- Integrated actuator platform for real-time whole-body control
- Used across AI Sapiens K1 for locomotion, posture, and upper-body motion
AI Sapiens K1
A Humanoid Platform for Physical AI
AI Sapiens K1 brings DYNAMIXEL-Q actuators, robot software, simulation assets, training workflows, and deployment guides into one humanoid platform. It is designed for researchers, educators, and developers working on locomotion, motion generation, reinforcement learning, imitation learning, and real-world deployment.
Whole-Body Motion
Arms, legs, and waist for full humanoid movement.
Real Contact
Develop against real hardware, not simulation only.
Open Stack
Hardware, software, simulation, and learning resources.
From Simulation to Real Humanoid Behavior
One Platform for Learning, Control, and Deployment
AI Sapiens K1 connects simulation, training, control, and real-world execution so users can develop policies and validate them on DYNAMIXEL-Q powered hardware.
01
Model & Simulate
Develop motion and policies in simulation using robot assets and physics-based training workflows.
02
Train Policies
Use reinforcement learning and imitation learning workflows for locomotion and repeatable robot behavior.
03
Deploy to K1
Transfer commands through ROS 2 control to DYNAMIXEL-Q actuators on the real humanoid.
04
Validate on Hardware
Test against real dynamics, contact, balance, and actuator feedback for practical Physical AI iteration.

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.
Reinforcement Learning
Train Locomotion, Then Validate on Hardware
AI Sapiens supports reinforcement learning workflows for locomotion development, helping users iterate in simulation and reduce the gap between policy training and real humanoid deployment.
Imitation Learning
From Human Demonstration to Robot Behavior
Demonstration data can be collected, structured for training, and transferred back to the robot so learned behaviors can be tested as natural, repeatable motion on DYNAMIXEL-Q powered hardware.
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.
