Notable
The S1 is an upper-body humanoid on a 3-DOF omnidirectional wheeled base (23 total DOF: two 7-DOF cable-driven arms, 4-DOF torso, 2-DOF head, 3-DOF base) — a high-speed dexterous mobile manipulator, not a bipedal walker. It went viral in April 2024 demonstrating cooking, cleaning, and calligraphy with end-effector speeds of ~10 m/s and +/-0.1 mm repeatability.
