Learning-based controllers have recently garnered significant attention for their impressive performance on legged robots. This control methodology, initially met with skepticism by the majority of the legged robotics community, now stands at the forefront of advancements in the field. Nonetheless, these controllers still exhibit a tendency toward short-sightedness, struggling to tackle dynamically complex, long-horizon challenges. Furthermore, many of them lack the capacity to integrate established vision and planning algorithms that have proven effective over several decades. During this presentation, I will outline our endeavors in formulating a comprehensive control solution tailored for legged robots. At Railab, KAIST, we have been dedicated to the development of a complete legged robotics system, encompassing hardware design, dynamic modeling, physics simulation, state estimation, control algorithms, and planning methodologies. This holistic approach equips us with the expertise needed to devise robust and pragmatic controllers capable of navigating demanding real-world terrains.
