HOIST: Humanoid Optimization with Imitation and Sample-efficient Tuning for Manipulating Suspended Loads
Songyang Liu, Shunyu Yao, Dingyuan Huang +1
Manipulating suspended payloads with humanoid robots is challenging because the robot can only influence an underactuated, oscillatory load through whole-body motion and intermitte…
Learning Spatial Awareness for Laparoscopic Surgery with AI Assisted Visual Feedback
Songyang Liu, Yunpeng Tan, Shuai Li
Laparoscopic surgery constrains surgeons spatial awareness because procedures are performed through a monocular, two-dimensional (2D) endoscopic view. Conventional training methods…
Large-Scale Mixed-Traffic and Intersection Control using Multi-agent Reinforcement Learning
Songyang Liu, Muyang Fan, Weizi Li +2
Traffic congestion remains a significant challenge in modern urban networks. Autonomous driving technologies have emerged as a potential solution. Among traffic control methods, re…
Heterogeneous Mixed Traffic Control and Coordination
Iftekharul Islam, Weizi Li, Xuan Wang +2
Urban intersections with diverse vehicle types, from small cars to large semi-trailers, pose significant challenges for traffic control. This study explores how robot vehicles (RVs…
