A Kinematic Modeling and Control Scheme for Different Robotic Endoscopes: A Rudimentary Research Prototype

RA-L 2022

In image-guided robotic surgery, there exist different endoscopes coupled either with specialized surgical robots (SSRs) or general industrial robots (GIRs). In general, SSRs mechanically respect the remote-center-of-motion (RCM) constraints with directly and explicitly controllable degrees-of-freed

FlexiVision: Teleporting the Surgeon’s Eyes via Robotic Flexible Endoscope and Head-Mounted Display

IROS 2020poster

A flexible endoscope introduces more dexterity to the image capturing in endoscopic surgery. However, manual control or automatic control based on instrument tracking does not handle the misorientation between the endoscopic video and the surgeon. We propose an automatic flexible endoscope control m…

Visual Servo of a 6-DOF Robotic Stereo Flexible Endoscope Based on da Vincix Research Kit (dVRK) System

RA-L 2020

Endoscopes play an important role in minimally invasive surgery (MIS). Due to the advantages of less occupied motion space and enhanced safety, flexible endoscopes are drawing more and more attention. However, the structure of the flexible section makes it difficult for surgeons to manually rotate a

Autonomous Flexible Endoscope for Minimally Invasive Surgery With Enhanced Safety

RA-L 2019

Automation in robotic surgery has become an increasingly attractive topic. Although full automation remains fictional, task autonomy and conditional autonomy are highly achievable. Apart from the performance of task fulfillment, one major concern in robotic surgery is safety. In this paper, we prese
