RoMeLa (Robotics & Mechanisms Laboratory), UCLA · research humanoid
ARTEMIS
A full-size research biped from Dennis Hong's RoMeLa lab at UCLA, built for fast, robust walking and running on rough ground and in soccer. Its custom electric actuators are springy and force-controlled like muscles, so it stays upright when shoved; the lab later open-sourced its design, model and baseline controllers.

Why it matters
UCLA billed it as the fastest-walking humanoid at 2.1 m/s in lab tests, and two ARTEMIS robots won every match of the RoboCup 2024 adult-size soccer tournament, scoring 45 goals.
Real-world use
Played RoboCup 2023 in Bordeaux and won the RoboCup 2024 adult-size humanoid soccer title in Eindhoven (July 2024).

Side by side with its peers
Picked by the same rules for every humanoid: another maker’s robot that moves the same way, is at the same stage and does at least one of the same main jobs, first shown within two years. Closer size and price rank higher. Few robots match closely, so these are the nearest matches. How we choose
