A Cross-Entropy Motion Planning Framework for Hybrid Continuum Robots

RA-L 2023

The sampling-based motion planners, including the Rapidly-exploring Random Trees (RRT) algorithms, are widely utilized in continuum robots, enabling efficient search for feasible motion plans in constrained environments. In surgical robotics, complex mapping among the high-dimensional kinematics of

A Variable Length, Variable Stiffness Flexible Instrument for Transoral Robotic Surgery

RA-L 2022

Transoral robotic surgery (TORS) in upper aerodigestive tract remains challenging due to the rigidity and insufficient workspace of existing instruments, and inappropriate balance between compliance and stiffness in flexible instruments. In this letter, a flexible surgical robotic instrument, featur

Towards Safe Control of Continuum Manipulator Using Shielded Multiagent Reinforcement Learning

RA-L 2021

Continuum robotic manipulators are increasingly adopted in minimal invasive surgery. However, their nonlinear behavior is challenging to model accurately, especially when subject to external interaction, potentially leading to poor control performance. In this letter, we investigate the feasibility
