About

Sina Nia Kosari is a leading researcher in surgical robotics, with key contributions in open-platform robot design, cable-driven mechanism control, and autonomous tissue interaction. Her most impactful work is the Raven-II, an open platform for collaborative surgical robotics research that has garnered 374 citations and is used by seven universities worldwide. This system features two 3-DOF spherical positioning mechanisms with interchangeable instruments, enabling advances in robot-assisted surgery. Kosari also pioneered methods for estimating and compensating cable tension in cable-driven mechanisms, addressing a critical challenge in haptic devices and surgical robots. Her work on forbidden region virtual fixtures from streaming point clouds (22 citations) introduced real-time haptic protection using RGB-D cameras, enhancing teleoperation safety. Additionally, she applied the Unscented Kalman Filter to improve state-space control in cable-driven surgical robots (17 citations) and investigated automated soft tissue compression for robot-assisted surgery (5 citations), tackling fundamental tasks in tissue interaction. Kosari’s research bridges hardware platforms, control theory, and autonomous surgical tasks, making her a pivotal figure in advancing surgical robotics for both research and clinical applications.
