Le Xu, Ruoyu Ren, Xiaojie Wei, Hao Lee, Hank Zhang, Kaicheng Yu +4

IROS 2025

This paper presents a deformable spherical robot with a six-strut topological structure capable of achieving multimodal locomotion in complex amphibious environments. The robot realizes isotropic rolling and asymmetric jumping through its innovative geometric-based configuration while integrating an

Lower Limb Exoskeleton - Energy Optimization of Bipedal Walking With Energy Recycling - Modeling and Simulation

Hao Lee, Jacob Rosen

RA-L 2023

Humans tend to use more energy to walk compared to other limb-based locomotion animals. This higher energy usage is due to “heel strikes” and “negative work” during human gait. Passive walkers elevate this phenomenon by utilizing elastic joints that absorb/reuse some of the negative work. The object
