In mid‑July 2026, researchers at South Korea’s Mid‑July 2026 saw KAIST unveiled unveil the KAIST Hound, a four‑legged robot that uses a transformer‑based reinforcement‑learning controller (APT‑RL) to select quadruped that autonomously selects walking, running or jumping gaits in real time based on terrain cues. Outdoor tests showed stable movement at up to 22 km/h and autonomous gait switching on negotiate stairs, stones, gaps and forest paths, positioning the platform for disaster response, defence and industrial inspection. trails at up to 22 km/h. Two weeks later, China’s later Unitree Robotics introduced the Super Athlete AS2‑W, a hybrid wheel‑leg robot platform that can sprint up to 30 km/h in short bursts and cruise at 3.7 m/s while carrying 16 kg. The design combines rapid wheel‑driven travel bursts (30 km/h) with legged agility, allowing the robot to traverse handling 45° slopes, 80‑cm steps and water streams. With a three‑hour endurance on streams while carrying 16 kg and sustaining a single 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 water‑resistance (IP54), Unitree markets the robot ability to climb stairs and steep obstacles, reinforcing its suitability for hard‑to‑reach industrial inspection, logistics, exploration inspection and search‑and‑rescue. civilian tasks. Together, the two releases illustrate these advances highlight a rapid progress across Asia in AI‑driven, Asian push toward more energy‑efficient, load‑capable and terrain‑adaptive quadruped robotics, with each effort emphasizing different performance traits—KAIST’s focus on versatile gait selection and Unitree’s hybrid speed robots for disaster response, logistics and endurance—broadening the potential applications of rugged mobile robots. inspection.
