项目摘要

This project will advance the progress of science, national prosperity and welfare, by enhancing walking capabilities of robotic systems. While legged robots are becoming more mechanically sophisticated, their agility, dexterity, and dynamic stability are still far from capabilities of their biological counterparts (such as animals and humans) in real world situations. The overarching goal of this project is to create a formal foundation to enable intelligent and fast motion planning, safety, and robust control for a multitude of agile behaviors of autonomous legged machines in real-world situations. This research will have broad societal impact through seamless integration of control theory, optimization, and intelligence to enable ubiquitous use of increasingly sophisticated robots. Such robots will be able to effectively assist, or serve as remote extensions of, humans in situations of extreme danger, such as industrial accidents and natural disasters. The integrated educational plan will have broad impact by designing new courses. STEM-based outreach initiative for K-12 students, teachers, and under-represented minorities, and engagement of undergraduate students in research.The project will advance knowledge in the largely unexplored field of intelligent and robust legged locomotion through key innovations in controls and analysis. Intelligent and fast motion planning algorithms, based on hybrid systems theory, optimization, and perception, will be created for dynamical models of legged locomotion in complex environments. The project will address the synthesis of robust-optimal controllers, based on nonlinear control and matrix inequalities, for agile and dexterous locomotion. It will also create safety-critical control algorithms, based on set invariance and quadratic programming, for real-world implementation of robust controllers that guarantee obstacle avoidance in unknown environments. To bridge the gap between theory and implementation, this research will transfer the theoretical innovations into practice through experiments with two advanced quadrupedal and bipedal robots in researchers' laboratories at Virginia Tech and Caltech sites.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目将通过提高机器人系统的行走能力来推动科学进步、国家繁荣和福利。虽然腿式机器人在机械上变得越来越复杂，但它们的敏捷性、灵活性和动态稳定性仍然远远低于它们在真实的世界中的生物对应物（例如动物和人类）的能力。该项目的总体目标是创建一个正式的基础，以实现智能和快速的运动规划，安全性和鲁棒性控制，以实现现实世界中自主腿式机器的多种敏捷行为。这项研究将通过控制理论、优化和智能的无缝集成产生广泛的社会影响，使日益复杂的机器人能够无处不在。这种机器人将能够在工业事故和自然灾害等极端危险的情况下有效地协助人类，或作为人类的远程延伸。综合教育计划将通过设计新的课程产生广泛的影响。为K-12学生，教师和代表性不足的少数民族提供基于STEM的外展计划，并让本科生参与研究。该项目将通过控制和分析方面的关键创新，在智能和健壮的腿部运动这一基本上未被探索的领域推进知识。智能和快速的运动规划算法，基于混合系统理论，优化和感知，将创建在复杂环境中的腿运动的动力学模型。该项目将解决的鲁棒最优控制器的合成，基于非线性控制和矩阵不等式，敏捷和灵巧的运动。它还将创建基于集合不变性和二次规划的安全关键控制算法，用于在未知环境中保证避障的鲁棒控制器的实际实施。为了弥合理论与实践之间的差距，该研究将通过在弗吉尼亚理工大学和加州理工大学的研究人员实验室中使用两个先进的四足和双足机器人进行实验，将理论创新转化为实践。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
