His research interests include multi-robot collaboration, task and motion planning, and machine learning. A long-term goal of his research is to develop algorithms that enable individual robots and robot teams to accomplish complex and long-horizon tasks in dynamic and uncertain environments.
Publications
Yorai earned a B.Sc. in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology in 2021. His research interests span multi-robot task and motion planning, robotic manipulation, statistical learning, and computer vision. He works to harness insights from established planning algorithms to address messy real-world challenges in manipulation.
Publications
Rishi works with Professors Maxim Likhachev and Jiaoyang Li in the Robotics Institute at CMU and is supported by the NSF Graduate Research Fellowship. His specific research interest is in (1) designing better heuristic search algorithms, (2) multi-agent motion planning and coordination (e.g. MAPF), and (3) combining search with machine learning. Previously, he double majored in EECS and Applied Math at UC Berkeley and was very active in teaching (EE16A, CS188, CS170 x2).
Publications
Jingtian received a B.Sc. from Zhejiang University in 2020 and an M.Sc. from the Carnegie Mellon University in 2023. His research interests include multi-robot coordination, autonomous exploration, and Multi-Agent Path Finding.
Publications
Yulun received a B.Sc. and an M.Sc. in Computer Science from the University of Southern California in 2021 and 2022.
