Towards Dynamic Model Identification and Gravity Compensation for the dVRK-Si Patient Side Manipulator
Haoying Zhou, Hao Yang, Brendan Burkhart +5
The da Vinci Research Kit (dVRK) is widely used for research in robot-assisted surgery, but most modeling and control methods target the first-generation dVRK Classic. The recently…
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…
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…
