Design and Motion Control of Master–Slave Control Endotracheal Intubation Robot

Abstract

Background: Master–slave remote control technology allows patients to be treated promptly during transport and also reduces the risk of contagious infections. Endotracheal intubation, guided by endoscopy and a master–slave system, enables doctors to perform the procedure efficiently and accurately. Methods: In this paper, we present the development of a master–slave controlled endotracheal intubation robot (EIR). It is based on operation incremental mapping, a weighted recursive average filtering method to reduce vibration, and a virtual fixture designed to reduce mishandling in minimally invasive surgery. Results: Simulation analysis of the master–slave control demonstrates that the weighted recursive average filtering method effectively reduces vibration, while the virtual fixture assists in confining the operator's movement within a delimited area. Experimental validation confirms the validity of the robot's structural design and control method. Conclusions: The developed robot successfully achieves the necessary motion for endotracheal intubation surgery through master–slave control.
