Chao CaoI am a third-year Ph.D. student at The Robotics Institute, Carnegie Mellon University advised by Ji Zhang and Howie Choset. I serve as the planning team lead of Team Explorer competing in the DARPA Subterranean Challenge. For a teaser, check out this cool video from Microsoft and the compilation of our Urban Circuit performance ! I have an MS in Robotics from CMU RI, where I was advised by Matt Travers and Howie Choset. I obtained my BS in Computer Science from The Univeristy of Hong Kong, where I worked with Jia Pan and Wenping Wang. I'm interested in robot navigation and motion planning. My recent work has been on exploration and sensor coverage planning. Home / Robots / Google Scholar / CV |

TARE: A Hierarchical Framework for Efficiently ExploringComplex 3D EnvironmentsChao Cao, Hongbiao Zhu, Howie Choset, Ji Zhang Robotics: Science and Systems(RSS), 2021 Best Paper Award and Best Systems Paper Award website / video / A hierarchical framework for autonomous exploration in large-scale environments. This work won the Best Paper Award and Best Systems Paper Award of RSS 2021, which is the first time that one paper won both awards in the history of RSS. |
Hierarchical Coverage Path Planning in Complex 3D EnvironmentsChao Cao, Ji Zhang, Matt Travers and Howie Choset IEEE International Conference on Robotics and Automation (ICRA), 2020 video / A multi-resolution hierarchical framework for sensor coverage planning. It solves a high-level Traveling Salesman Problem (TSP) for a global tour, which is then used for assembling low-level trajectories obtained by solving local Orienteering Problems. The hierarchical scheme produces much higher efficiency than the state-of-the-art. |
Dynamic Channel: A Planning Framework for Crowd NavigationChao Cao, Peter Trautman and Soshi Iba IEEE International Conference on Robotics and Automation (ICRA), 2019 arxiv / website / video / A hierarchical planning framework for crowd navigation. It incorporates a global planner to find feasible paths in the topological space efficiently, and a local planner to follow the path with optimized trajectories. |
