Advancements in Bipedal Systems and Humanoid Robotics

The field of bipedal systems and humanoid robotics is moving towards a more integrated approach, combining control policies and physical morphology to achieve stable and efficient locomotion. Researchers are exploring the use of feedforward stabilization and co-design principles to reduce control effort and energy expenditure, and to enhance the robustness of bipedal systems. Notably, the development of scalable frameworks for fall recovery and whole-body reactions in contact-rich environments is gaining traction. These advancements have the potential to significantly improve the autonomy and versatility of humanoid robots. Noteworthy papers include: Estimation of Minimum Stride Frequency for the Frontal Plane Stability of Bipedal Systems, which proposes a method to predict the minimum stride frequency required for stable oscillations. Toward Humanoid Brain-Body Co-design: Joint Optimization of Control and Morphology for Fall Recovery, which presents a co-design framework for fall recovery that achieves an average performance gain of 44.55% on seven public humanoid robots. Embodied Intelligence for Advanced Bioinspired Microrobotics: Examples and Insights, which discusses the use of embodied intelligence as a design principle for advanced microrobotics. Thor: Towards Human-Level Whole-Body Reactions for Intense Contact-Rich Environments, which introduces a humanoid framework for human-level whole-body reactions in contact-rich environments, achieving substantial improvements in force-interaction tasks.
