Mid‑July 2026 saw KAIST unveil the Hound, a transformer‑based reinforcement‑learning quadruped that autonomously selects walking, running or jumping gaits to negotiate stairs, stones, gaps and forest trails at up to 22 km/h. Two weeks later Unitree Robotics introduced the Super Athlete AS2‑W, a hybrid wheel‑leg platform that combines rapid wheel‑driven bursts (30 km/h) with legged agility, handling 45° slopes, 80‑cm steps and water streams while carrying 16 kg and sustaining a 150 kg static load.

In early August, researchers at Seoul National University of Science and Technology reported lightweight, porous 3D‑printed feet that reduce quadruped battery draw by up to 6.2 %. The diamond‑shaped foot design, paired with deep‑reinforcement‑learning gait optimisation, improves energy recovery without sacrificing strength.

Unitree’s updated As2‑W model, now weighing 25 kg, retains a top speed of 22 km/h, a 16 kg payload capacity and the ability to climb stairs and steep obstacles, reinforcing its suitability for industrial inspection and civilian tasks. Together, these advances highlight a rapid Asian push toward more energy‑efficient, load‑capable and terrain‑adaptive quadruped robots for disaster response, logistics and inspection.
