45 kilogram robot demonstrated its abilities by moving from a fixed position at a speed of 3 meters per second. HOUND’s mechanical design played a critical role in their success, using advanced reinforcement learning techniques for optimal intelligent behavior.

HUND abilities

HOUND is able to navigate a variety of surfaces, including grass and steep slopes of 22 degrees, thanks to the optimized mechanical design, especially the configuration of the motor controller and gearbox.

Working in parallel, the hip and knee drive modules use a hollow shaft to transmit power, while the belt and pulley system for the knee joint provides a wide range of motion.

Engineers also used a planetary gearbox, which transfers power effectively and therefore increases the overall efficiency of the robot.

The developer of the robot, Yeon-Ha Shin, emphasized that complex movements are performed with assistance. single motor controllerIn order to improve the performance of the actuator, he was trained in a simulation that takes into account the characteristics of the engine to create an environment close to real conditions.

Although HOUND’s success is remarkable, it is worth noting that it falls short of breaking the speed record set by DARPA’s Cheetah in 2012, reaching 45.5 km/h from a distance of 20 meters.
