Semi-distributed Cross-modal Air-Ground Relative Localization

IROS 2025

Efficient, accurate, and flexible relative localization is crucial in air-ground collaborative tasks. However, current approaches for robot relative localization are primarily realized in the form of distributed multi-robot SLAM systems with the same sensor configuration, which are tightly coupled w

Vision-Based Markerless Tracking for Continuum Surgical Instruments in Robot-Assisted Minimally Invasive Surgery

RA-L 2023

Robotic-assisted single-port minimally invasive surgery (MIS) can reduce trauma and shorten hospitalization. However, surgical instruments for robotic single-port surgery usually possess multiple joints without distal joint sensors. Hence, closed-loop control is not directly applied to these joints,

Inverse Kinematics and Dexterous Workspace Formulation for 2-Segment Continuum Robots With Inextensible Segments

RA-L 2022

The inverse kinematics (IK) problem of continuum robots has been investigated in depth in the past decades. Under the constant-curvature bending assumption, closed-form IK solution has been obtained for continuum robots with variable segment lengths. Attempting to close the gap towards a complete so

Closed-Loop Pose Control and Automated Suturing of Continuum Surgical Manipulators With Customized Wrist Markers Under Stereo Vision

RA-L 2021

The use of continuum manipulators in surgical applications can be beneficial because of their inherent safety from their structural compliance. However, the tip pose (position and orientation) accuracy of a continuum manipulator can be low when an external load or disturbance is applied. Closed-loop
