Overview

South Korea's open-source answer to the Unitree G1. ROBOTIS — 25-year actuator veteran behind the DYNAMIXEL line — built the AI Sapiens K1 as a physical-AI research platform: 136 cm, 35 kg, 23 DOF on in-house DYNAMIXEL-Q quasi-direct-drive actuators, NVIDIA Jetson Orin NX and ROS 2. The differentiator is radical openness: hardware BoM, CAD/STEP files, source code, simulation assets and training workflows are all published, with imitation-learning leader-follower data collection built in. Target price ~$7,000-8,000 undercuts most research humanoids.
