Dynamic Model Identification and Gravity Compensation for the dVRK-Si Patient Side Manipulator
Haoying Zhou, Hao Yang, Brendan Burkhart +6
The da Vinci Research Kit (dVRK) has been widely used for research in robot-assisted surgery over the past decade, and its latest generation, the dVRK-Si was made publicly availabl…
Sensorless Remote Center of Motion Misalignment Estimation
Hao Yang, Lidia Al-Zogbi, Ahmet Yildiz +2
Laparoscopic surgery constrains instrument motion around a fixed pivot point at the incision into a patient to minimize tissue trauma. Surgical robots achieve this through either h…
Gravity Compensation of the dVRK-Si Patient Side Manipulator based on Dynamic Model Identification
Haoying Zhou, Hao Yang, Anton Deguet +3
The da Vinci Research Kit (dVRK, also known as dVRK Classic) is an open-source teleoperated surgical robotic system whose hardware is obtained from the first generation da Vinci Su…
A Hybrid Model and Learning-Based Force Estimation Framework for Surgical Robots
Hao Yang, Haoying Zhou, Gregory S. Fischer +1
Haptic feedback to the surgeon during robotic surgery would enable safer and more immersive surgeries but estimating tissue interaction forces at the tips of robotically controlled…
An Effectiveness Study Across Baseline and Learning-based Force Estimation Methods on the da Vinci Research Kit Si System
Hao Yang, Ayberk Acar, Keshuai Xu +3
Robot-assisted minimally invasive surgery, such as through the da Vinci systems, improves precision and patient outcomes. However, da Vinci systems prior to da Vinci 5, lacked dire…
