- 요약This dissertation develops a unified framework for building safe, agile, and intelligent legged robotic systems, inspired by the concept of the Robot Cerebellum which is the part of the brain responsible for body coordination and motion control. The core challenge addressed is how to enable versatile and dynamic maneuvers, i.e., to develop the cerebellum, in complex and underactuated robotic systems such as legged robots by integrating model-based optimal control and model-free reinforcement learning (RL). The work begins with structured motion control, introducing model-based locomotion frameworks to achieve expressive and robust locomotion. To unlock the full potential and agility of legged robots, this dissertation then presents a novel general locomotion control framework using model-free RL on a person-sized bipedal robot in the real world. This framework demonstrates a range of novel bipedal locomotion capabilities, including walking with compliance and persistent performance over a long timespan (1.5 years), running (including a 400-meter dash), and multi-axis targeted jumping such as standing long jumps and table jumps, with significant robustness and adaptivity. Building on this foundation, the dissertation introduces HiLMa, a hierarchical framework for whole-body loco-manipulation, enabling legged robots to function beyond locomotion and perform complex object interaction tasks using their legs as arms while in locomotion. It further extends to agent interaction, exploring both centralized and decentralized coordination strategies for human-robot and multi-robot collaboration in congested environments. Finally, the dissertation addresses safety by bridging model-based motion planning with learning-based controllers. Through system identification, it unveils hidden low-dimensional linear behavior of the closed-loop systems using RL policies, which is then embedded into an model-based framework to achieve certifiably safe navigation while preserving learned agility. Together, these contributions advance the state of the art across locomotion control, planning, learning, safety, and physical interaction using legged robots in real-world settings, paving the way to extend the cerebellar core into a broader Robot Brain for future robotics across a wide range of real-world tasks and environments.
