Design of a trajectory contour controller for a dual‐axis precision motion stage based on improved iterative learning

IET Control Theory &Applications, Volume 17, Issue 17, Page 2280-2291, November 2023., 2023
Here, the Contour Error(CE) in the precision motion control of a dual‐axis planar mechanism is addressed. The Precompensation Cross‐Coupling Iterative Learning Control with Variable Forgetting Factor (pre‐CCILC+VFF‐VGILC) control strategy significantly improve the “single‐axis Tracking Error (TE) and dual‐axis CE” under repeated trajectories.

Review on human‐like robot manipulation using dexterous hands

Cognitive Computation and Systems, Volume 5, Issue 1, Page 14-29, March 2023., 2023
Abstract In recent years, human hand‐based robotic hands or dexterous hands have gained attention due to their enormous capabilities of handling soft materials compared to traditional grippers. Back in the earlier days, the development of a hand model close to that of a human was an impossible task but with the advancements made in technology ...

HeterBot: A heterogeneous mobile manipulation robot for versatile operation

IET Cyber-Systems and Robotics, Volume 5, Issue 1, March 2023., 2023
Abstract This study presents the overall architecture of HeterBot, a heterogeneous mobile manipulation robot developed in our lab, which is designed for versatile operation in hazardous environments. The most significant feature of HeterBot is the heterogeneous design created by adopting the idea of ‘big arm + small arm’ and ‘big car + mini car’.

Magnetically Guided Laser Surgery for the Treatment of Twin‐to‐Twin Transfusion Syndrome

Advanced Intelligent Systems, Volume 4, Issue 11, November 2022., 2022
Twin‐to‐twin transfusion syndrome (TTTS) is a severe disorder that often leads to the death of monochorionic twin fetuses, if left untreated. Herein, a robotic platform to perform TTTS surgery using remote magnetic navigation is presented. In contrast to rigid tools, the custom magnetic fetoscope is highly flexible, dexterous, and has considerable ...
